In plants, __________ are the cell junctions that allow the free exchange of small molecules that assist in communication. In animal cells, similar cell junctions are known as __________.
Answer:
1. Plasmodesmata
2. Gap junctions
Explanation:
In a multicellular organism, the cell communicates to another cell in via direct cell to cell contact between them which allows the cells to perform intercellular communication which differs in the plant, animal and fungal cell.
In-plant cell, the intercellular communication takes place through the plasmodesmata connections which are formed between two adjacent plant cell walls. The plasmodesmata connection allows the exchange of cytoplasmic material between the cells.
In animal cells, the cells communicate to another cell through Gap junctions which are formed by the connexon pores which allows the exchange of material between animal cells.
Thus, Plasmodesmata and Gap junctions are correct.
Final answer:
In plants, plasmodesmata are the cell junctions that allow the free exchange of small molecules that assist in communication. In animal cells, similar cell junctions are known as gap junctions.
Explanation:
In plants, plasmodesmata are the cell junctions that allow the free exchange of small molecules that assist in communication. In animal cells, similar cell junctions are known as gap junctions. Plasmodesmata are specialized openings in cell walls through which the cytoplasm of adjacent cells can connect, facilitating the transport of various substances such as ions and nutrients. Gap junctions in animal cells serve a similar function; they are channels that permit the transfer of molecules and ions between neighboring cells, enabling intercellular communication. Although functionally similar, plasmodesmata and gap junctions differ structurally. These intercellular junctions are crucial for maintaining the physiological processes that keep tissues and organs functioning properly.

Explanation:
Discuss how the endocrine system and nervous systems become involved when a student feels stress--such as that associated with an upcoming exam. Be detailed and cite sources in this weeks posting.
Explanation:
Stress response by the body is regulated by the nervous system. As the day of the exam draws by, the cerebral cortex of the student activates the hypothalamus that triggers hormones to be released that activates the systemic branch of the autonomic nervous and endocrine system (Larissa, 2018). The autonomic nervous system controls involuntary bodily responses such as breathing, heartbeat, and digestion. The endocrine system contains glands that secrete hormones into the bloodstream that regulate the functions of body organs. The student's pituitary gland in response to the activated hypothalamus, which would secrete a hormone which in turn triggers the release of stress hormones from the adrenal glands and it would help the student manage stress by making nutrients available to meet the demand for energy. These hormones activate the sympathetic division of the autonomic system, causing increased heart rate, breathing, and blood pressure and the suppression of digestion (America psychological association, 2019). After the exam, the student is restored to a less tressful state. The parasympathetic branch of the autonomic system would slow the student's heartbeat and breathing and digestive processes would no longer be suppressed and the student gains appetite for food (BcCampus, 2019).
Final answer:
When a student feels stressed, the nervous and endocrine systems collaborate to initiate the body's stress response, releasing hormones like cortisol and epinephrine. This results in physiological changes such as increased heart rate and alertness. Chronic stress can impact health by affecting hormone levels and weakening the immune system.
Explanation:
When a student feels stress, such as that associated with an upcoming exam, both the endocrine system and nervous system become actively involved in generating a response to manage this stress. The nervous system, through the hypothalamus, activates the adrenal glands, signaling them to release cortisol and epinephrine (adrenaline), hormones that play key roles in the body's stress response. This intricate interplay leads to physiological changes such as increased heart rate, heightened alertness, and energy mobilization - all part of the body's 'fight or flight' response.
The endocrine system directly impacts emotional and physical health by regulating hormones related to stress. For instance, cortisol helps mobilize glucose to give the body a quick energy boost, while adrenaline increases heart rate and blood pressure. Over time, chronic stress can lead to sustained high levels of these hormones, potentially weakening the immune system and contributing to a range of health issues.
Understanding the connection between stress, the nervous system, and the endocrine system highlights the importance of stress management techniques to maintain both physical and psychological well-being. Engaging in activities like exercise, meditation, or deep-breathing exercises can help mitigate the impact of stress on the body by regulating hormone levels and supporting immune system function.
Referring to a plant's sexual life cycle, which of the following terms describes the process that leads directly to the formation of gametes?
a. sporophyte meiosis
b. gametophyte mitosis
c. gametophyte meiosis
d. sporophyte mitosis
e. alternation of generations
Answer:
b. gametophyte mitosis
Explanation:
Plants have diploid sporophyte generation. The diploid spore mother cells of the sporophyte generation undergo meiosis to produce haploid spores. These spores divide by mitosis to produce haploid gametophyte. Therefore, plants have haploid gametophytes. These haploid gametophytes form gametes by mitosis. So, gametophyte mitosis gives rise to gametes in plants.
For example, the haploid microspores are produced in anthers of flowering plants by meiosis in the microspore mother cells. These haploid microspores give rise to haploid gametophytes which in turn divide mitotically to produce haploid male gametes.
The formation of gametes in a plant's sexual life cycle is due to gametophyte mitosis. The sporophyte, after meiosis, produces spores, which develop into gametophytes. The gametophytes then undergo mitosis to create the male and female gametes.
Explanation:The process that leads directly to the formation of gametes in a plant's sexual life cycle is b. gametophyte mitosis.
In the plant's life cycle, the sporophyte undergoes meiosis to produce spores, which develop into gametophytes. The gametophytes then undergo mitosis to form the male and female gametes.
After these gametes meet in the process called fertilization, they form a zygote, leading to the sporophyte again. This is known as the alternation of generations, but it is the gametophyte's mitotic division that specifically leads to gametes.

After morning class, with your stomach growling, you stagger to the cafeteria and devour a large pasta entree for lunch. Following this meal, your blood sugar rises and the pancreas releases ____________ in an attempt to shuttle blood sugar into your cells.
Answer:
Insulin
Explanation:
The main function of the pancreas is to maintain the bodies blood sugar by either releasing insulin or glucagon.
Glucagon are released by Alpha cells in the pancreas when the blood sugar levels are low that leads to the release of glucose into the blood.
Insulin is the hormone released by the Beta cells in the pancreas when the blood sugar rises. It regulates blood sugars by allowing the body cells to absorb and use the glucose in turn reducing the sugar levels.
Following this meal, your blood sugar rises and the pancreas releases insulin in an attempt to shuttle blood sugar into your cells.
After consuming a large pasta entree for lunch, the surge in blood sugar triggers the pancreas to release insulin. Insulin is a hormone crucial for regulating glucose levels in the bloodstream. Its primary role is to facilitate the uptake of glucose by cells, particularly muscle and adipose (fat) cells, for energy production and storage. In response to elevated blood sugar levels after a meal, insulin signals cells to increase their uptake of glucose, allowing them to use it for energy or store it for later use.
This process helps maintain blood sugar within a narrow and optimal range, preventing hyperglycemia. The pancreas acts as a key player in glucose homeostasis, releasing insulin when blood sugar levels rise and glucagon when they fall, ensuring a balanced and controlled metabolic environment. The intricate interplay between insulin, glucose, and cellular uptake is essential for energy regulation in the body and underscores the significance of hormonal mechanisms in maintaining physiological balance.

Answer:
A molecule made primarily of amino acids with carbohydrate side chains would be described as a glycoprotein.
Endocytosis is the process of bringing substances into a cell
The structural framework of a cell is the cytoskeleton.
Small structures in the nucleus of cells responsible for producing ribosomal subunits are called nucleolus
The sequence on tRNA that is opposite to the codon on mRNA is the anticodon
The process during which a cell eats itself is referred to as autophagy
Explanation:
A glycoprotein is a protein that also contains carbohydrate side chains (i.e. it is not made up solely of amino acid chain). Glyco=sugar, so this is an easy way to remember what glycoproteins are. The carbohydrate side chains are covalently attached to the protein after the polypeptide has been synthesised and the protein has formed its structure. Glycoproteins are often important components of the cell membrane.
Endocytosis (endo means within, and cytosis means relating to the cell) refers to processes in which cells bring substances inside the cell. The substance is internalised by the movement of the cell membrane, which eventually envelopes the substance entirely and forms a vesicle. There are three different types, phagocytosis (cell eating), pinocytosis (cell drinking) and receptor-mediated endocytosis, which involves cell signalling through membrane receptors).
The cytoskeleton is an important structure, helping the cell maintain its shape, structure and internal organization. It also helps with cell movement and cell division. The cytoplasm is made up of different types of proteins that form microtubules and filaments, that work in a variety of ways to help the cell move, divide, form a stable structure and organise the organelles and other components.
The nucleolus is a sub-compartment of the eukaryotic nucleus that is principally known for its role in the transcription of ribosomal RNAs and ribosomal subunits, and is therefore crucial in ribosome biogenesis The nucleolus is not membrane bound, but it is a dense structure that is easy to identify in the mammalian nucleus.
tRNAs (or transfer RNAs) are important the translation of an mRNA sequence into a polypeptide sequence. The mRNA sequence can be divided into codons, each specifiying a particualr amino acid. The codons are translated into an amino acid sequence by tRNAs, which carry an anticodon sequence. tRNAs each possess an amino acid, and can recognise the mRNA codon through their anticodon, thereby assembling the correct sequence of amino acids in a synthesising protein.
Autophagy is an important process in the body, whereby unhealthy or damaged cells are targeted for destruction. This allows for the regeneration of new cells. This process involves a tightly regulated system, where cells are broken down and their components are recycled. This is an important anti-cancer mechanism.
A glycoprotein is a molecule made primarily of amino acids with carbohydrate side chains. Endocytosis is the process of bringing substances into a cell. The structural framework of a cell is the cytoskeleton.
Explanation:Molecule made primarily of amino acids with carbohydrate side chains:A molecule made primarily of amino acids with carbohydrate side chains is a glycoprotein. Glycoproteins are proteins that have carbohydrate groups attached to them. These carbohydrate side chains can have various functions, such as cell-cell recognition and cell signaling.
Process of bringing substances into a cell:The process of bringing substances into a cell is called endocytosis. Endocytosis is a cellular process in which the cell membrane invaginates, forming a vesicle that brings in extracellular molecules or particles into the cell.
Structural framework of a cell:The cytoskeleton is the structural framework of a cell. It is a network of protein filaments that provides structural support, maintains cell shape, and facilitates cell movement.
Small structures in the nucleus responsible for producing ribosomal subunits:The small structures in the nucleus responsible for producing ribosomal subunits are nucleoli. Nucleoli are dense regions within the nucleus where ribosomal RNA (rRNA) is synthesized and ribosomal subunits are assembled.
Sequence on tRNA opposite to the codon on mRNA:The sequence on tRNA that is opposite to the codon on mRNA is the anticodon. The anticodon is a three-nucleotide sequence on tRNA that is complementary to a specific codon on mRNA. It ensures the correct pairing between codons and amino acids during protein synthesis.
Process during which a cell eats itself:The process during which a cell eats itself is referred to as autophagy. Autophagy is a cellular process in which damaged organelles or proteins are wrapped in a membrane and digested by lysosomes.

Paul Baltes believes that natural selection has not weeded out many harmful conditions and nonadaptive characteristics that appear among older adults because those conditions are not tied to ______.
Answer:
Reproductive fitness.
Explanation:
The natural selection may be defined as one of the most important factors that plays the main role in evolution. Darwin explains the theory of the natural selection.
The organisms must adapt to their environment and reproduce in the large numbers. The reproductive fitness helps the individual to effectively transfer their genes to the next generation. The successfully adapted and evolved population must show high reproductive fitness. The natural selection increase the chance of individual to survive in harmful environmental conditions and do not remove the conditions.
Thus, the answer is reproductive fitness.
Final answer:
Natural selection has not eliminated many conditions in older adults as they do not affect reproductive success, highlighting a potential adjustment needed in the orthodox Darwinian view.
Explanation:
Paul Baltes suggested that natural selection has not eliminated many harmful conditions and nonadaptive characteristics appearing in older adults because those conditions are not tied to reproductive success. Essentially, if a deleterious trait or condition does not affect an individual's ability to reproduce and successfully rear offspring to reproductive age, such traits will continue to be passed on generationally. This is because natural selection can only act on characteristics that influence an organism's ability to produce and support viable offspring.
For example, a genetic predisposition to a condition such as Parkinson's disease, which typically manifests well after reproductive age, would not be weeded out by natural selection. This suggests an incomplete definition of natural selection, as it fails to account for such post-reproductive lifespan characteristics, leading to the consideration that adjustments or exceptions to the orthodox Darwinian view may be necessary.
What is the term for the procedure in which a woman’s ova are removed from her ovaries and a man’s sperm are used to fertilize the ova in a laboratory?
Answer:
In vitro fertilization (IVF)
Explanation:
In vitro fertilization is conducted when infertility is perceived in sexual partners trying to have a baby. It is the process whereby matured ova/eggs are removed from the female's reproductive system and is fertilized externally in a laboratory (usually in a glassware) using a male's sperm cell. It can be thought of as a procedure where the normal fertilization process that occurs in a female's reproductive tract (fallopian tube) is carried out outside the body, specifically in a laboratory.
In order for this procedure to be employed, the male and female must be able to produce their respective gametes. The female's ovary is usually stimulated by fertility drugs in order to yield numerous eggs, which are then extracted from her ovary and fertilized by a sperm externally (in a laboratory). The resulting fertilized egg called embryo is placed back into the female's womb to carry it as a normal pregnancy.
In 1859, a small colony of 24 rabbits was brought to Australia. By 1928 it was estimated that there were 500 million rabbits in a 1-million square mile section of Australia. Which statement describes a condition that probably contributed to the increase in the rabbit population?(1) The rabbits were affected by many limiting factors.(2) The rabbits reproduced by asexual reproduction.(3) The rabbits were unable to adapt to the environment.(4) The rabbits had no natural predators in Australia.
The rabbits had no natural predators in Australia.
Explanation:
'The rabbits were affected by many limiting factors.' This could not be a possibility because the limiting factors have a negative impact on growth rate of population. The limiting factors hinder the growth of population so if there were too many limiting factors affecting the rabbit, then the growth in population was not possible.The rabbits reproduced by asexual reproduction. Rabbits are mammals and it is a known fact that they reproduce sexually. Thus this option is not possible.The rabbits were unable to adapt to the environment If the rabbits were not adapted to the environment then they must not have survived efficiently in Australia. Hence, this is not a possibility.Thus, the only possibility that remains is that , The rabbits had no natural predators in Australia' Otherwise, the predators would have preyed upon the Rabbits and there population must not have increased in this rate.The wall of the left ventricle is thicker than that of the right and the left ventricle pumps more blood than the right. Are these two statements true or false?
The wall of the left ventricle is thicker than that of the right - True
The left ventricle pumps more blood than the right - False
Explanation:
Heart has 4 number of chambers. One among these chambers is the left ventricle. Among the four cambers of the heart, the thick one is the left ventricle. It appears below the left atrium. The left ventricle is present in the bottom left part of the heart. When the contraction of heart occurs the blood from the valve called mitral enters the left atrium from the left atrium.
The left ventricle transports the oxygenated blood to the human body. The left ventricle needs along these things for pumping the blood. The right ventricle can function by itself and is more powerful than left ventricle. The right ventricle is responsible in pumping blood to the lungs on its own.
