Ecological succession is a biological process where one group of species is gradually replaced with another over time. It's a key mechanism of the diversity in ecosystems. For example, after a wildfire, grasses may first colonize the land then be replaced by shrubs and eventually trees.
Explanation:The process where one group of species is replaced with others over time is called ecological succession. This biological phenomenon happens when an ecological community undergoes a series of changes which leads to the replacement of one group of species by another group. For instance, after a wildfire, the land may initially be colonized by grasses, then shrubs and eventually trees. In each stage of the process, the existing community modifies the environment in ways that make it suitable for the next stage. This constant process is what shapes the diverse ecosystems.

Answer: Option D) there are no holes for blood to enter or leave the system
The human cardiovascular system is considered closed because there are no holes for blood to enter or leave the system
Explanation:
The closed circulatory system are made up of blood vessels called arteries from the heart that branch into small units called capillaries but eventually join up with other blood vessels called veins that are connected to the heart. So, blood is always confined to circulate within the blood vessels and the heart as there are no holes for blood to enter or leave the system
Thus, the human cardiovascular system is considered closed

Scientists who wished to study the metabolic function of cells with balanced translocations while preventing cell replication would be best served by arresting the cells during which phase of the cell cycle?A. AnaphaseB. Metaphase
C. Interphase
D. Prophase
Answer:
C
Explanation:
This phase occurs before mitosis, it is here that the cell's DNA is copied in preparation for mitosis. This phase is also known as the metabolic phase (previously called the 'resting phase'), because it is during this phase that the cell gets it nutrients, breaks them down, and grows. It is therefore best to arrest the cell in this phase before any modifications happen to the cell during mitosis, and it is during this phase that the cell's metabolism is at its high functionality.
Which of the following statements about deuterostomes is false? Which of the following statements about deuterostomes is false? All deuterostomes are triploblastic and have three tissue layers. All deuterostomes exhibit radial symmetry in their bodies. All deuterostomes have a coelom. All deuterostomes have a similar pattern of early embryonic development.
Answer:
All deuterostomes exhibit radial symmetry in their bodies.Explanation:
deuterostomes : All deuterostomes are triploblastic and have 3 layers:
i) endoderm, ii) mesoderm and iii) Ectoderm
In deuterostomes , a mouth that develops separately from the blastopore.
Taxonomically, the deuterostomes defines as any member of the phyla (Chordata, Hemichordata, Echinodermata, etc) in which the anus appears first, and it develops at or near the blastopore.
All deuterostomes have a coelom.
All deuterostomes have a similar pattern of early embryonic development.
The false statement about deuterostomes is that they all exhibit radial symmetry, whereas they actually show bilateral symmetry. Deuterostomes are indeed triploblastic and have a coelom, sharing similar early embryonic development patterns.
Explanation:The correct statement that is false about deuterostomes is: All deuterostomes exhibit radial symmetry in their bodies. Deuterostomes, including humans, exhibit bilaterally symmetrical body plans rather than radial symmetry. While it is true that deuterostomes are triploblastic, meaning they develop three germ layers (the ectoderm, mesoderm, and endoderm), and possess a true coelom, they are characterized by their bilaterally symmetrical structure. Additionally, deuterostomes do follow a similar pattern of early embryonic development, specifically radial and indeterminate cleavage, which is different from the cleavage patterns seen in protostomes. However, the adult form of deuterostomes shows bilateral symmetry, making the statement about radial symmetry incorrect.
Scientists commonly choose white blood cells that are going through mitosis to prepare karyotypes. Why?
Answer:
This is because during the phase of mitosis, chromosomes of the white blood cells condense.
Explanation:
A karotype tells us about the appearance of a chromosome which involves the number of the chromosomes as well as the structure of the chromosomes.
Karotype can be used to detect any defect or abnormalities that can lead to sicknesses or health disorders in a person.
In order to prepare a karotype, white blood cells going through mitosis is used because during mitosis the chromosomes of the white blood cells condense thereby making movement easier for the cells.
Answer:
This is because during mitosis, chromosomes are more condensed than during interphase.
Explanation:
During interphase, the cell grows and the nuclear DNA is duplicated. Interphase is followed by the mitotic phase, individual chromosomes are not visible, and the chromatin appears diffuse and unorganized
During the mitotic phase, the duplicated chromosomes are segregated and distributed into daughter nuclei. The cytoplasm is usually divided as well, resulting in two daughter cells.

Other biologists of Darwin's time had proposed that living things had changed over time. Which feature distinguished Darwin's theory of evolution from the proposals of the other biologists?
Final answer:
Darwin's theory of evolution was distinguished from others by the concept of natural selection, where advantageous traits are passed on and lead to species evolution, a concept supported by his observations and later by genetics.
Explanation:
The feature that distinguished Charles Darwin's theory of evolution from the proposals of other biologists of his time was the concept of natural selection. While other scientists, such as Jean-Baptiste Lamarck, had suggested that species change over time, Darwin proposed that this change was due to the differential survival and reproduction of organisms with beneficial traits, which he termed natural selection. It was through natural selection that advantageous characteristics were passed down through generations, leading to the evolution of species.
Darwin's ideas were supported by his observations during the voyage of the HMS Beagle, particularly in the Galápagos Islands, where he saw unique species adaptations. His comprehensive explanation for the mechanism behind evolution was unprecedented and became a cornerstone of biology. Darwin's understanding of evolution by natural selection was further solidified with the understanding of genetics and the role of genes in heredity.

The endoplasmic reticulum is a membranous network distributed within the cell and is responsible for the transport of the proteins synthesized by the ribosomes.
The Golgi apparatus transport synthesized products to be secrete at the cell membranes. Glycoproteins are also manufactured at in the Golgi apparatus.
The vesicles act as storages in which these products are kept and it open up at the cell membrane to release them to the surroundings.
Answer:
D) ribosome, ER, Golgi apparatus, vesicle, cell membrane
Explanation:
This is the sequence of the pathways for the process of gene expression for protein synthesis.
It begins in the Ribosomes with the process of translation of the transcribed mRNA, to synthesise a polypeptide chain of Amino acids. These are passed into the rough- ER lumen or membrane.where they are modified; checked if the protein is well folded, and sugar molecules are also added . They are later packed in small coated vesicles en route the Golgi complex.
They are moved by cisternae migration by this vessicle, which are micro-tubules which makes use of cell cytoskeleton to navigate and move through the cytoplasm to trans-golgi ,,where they are sorted out .Some sugar molecules are removed while new are added. They are later transported to the trans-golgi network/ apparatus; for packaging to secretory vesicles and transport vesicles. The latter fused with the plasma membrane , and secreted to the outside by Exocytosis as uncoated protein.

Answer:
The entire process is called gene expression. In translation, messenger RNA (mRNA) is decoded in the ribosome decoding center to produce a specific amino acid chain, or polypeptide.
Explanation:
The process of decoding messenger RNA (mRNA) to make proteins is known as translation. This process, along with transcription, is part of gene expression which is central to protein synthesis and overall cellular function.
Explanation:The process of decoding messenger RNA (mRNA) to make proteins is called translation. During this process, the mRNA provides the information for the ribosome to catalyze protein synthesis. This process of translating a sequence of mRNA nucleotides into a sequence of amino acids is complex but systematic; for example, nucleotides 1 to 3 correspond to amino acid 1, nucleotides 4 to 6 correspond to amino acid 2, and so on. This biological mechanism is a part of what's known as the central dogma of molecular biology, which describes the flow of genetic information from DNA to RNA to protein. The entire process of gene expression, from transcription (DNA to RNA) to translation (RNA to protein), is essential for protein synthesis and cellular function.

In Mendel’s crosses, the trait is visible in the F2 generation, but not the F1 generation.
Answer:
In Mendel’s crosses, the recessive trait is visible in the F2 generation, but not the F1 generation.
After crossing a tall pea plant with a short pea plant, all of Mendel’s pea plants were tall because it is the Dominant trait.
For seed color, the F2 generation produced both yellow and green seeds because there are two different alleles for each gene.
If you'd like to know more, read on:
Alleles are variants of genes that control traits. There are two alleles called the dominant and recessive allele.
A dominant allele is a trait that is physically expressed even when coupled with a recessive allele. A recessive allele on the other hand is the trait that is masked by the dominant allele.
This is what happened in Mendel's crosses. He crossed a true-breeding tall plant with a true breeding short plant.
P generation
TT - Tall plant
tt - Short plant
The result in the F1 generation that consisted only of Tt plants, where the dominant allele was expressed.
T T
t Tt Tt
t Tt Tt
Then he crossed the F1 generation to produce the F2 generation.
Tt x Tt
The results:
T t
T TT Tt
t Tt tt
As you can see the resulting offsprings shows that the recessive trait occurring, tt. This means that there was a 25% chance that the off springs produced would short plants and 75% that the offsprings produced is tall. This applies also to the color of the seeds if we cross the pea plants based on the color of seeds.
Explanation:
In Mendel's cross, the recessive trait appears in the [tex]F_2[/tex] generation, but not in the [tex]F_1[/tex] generation.
What is Mendel's cross?After crossing a tall pea plant with a short pea plant, all of Mendel's pea plants were tall because of the dominant trait. For seed color, the [tex]F_2[/tex] generation produced both yellow and green seeds because there are two different alleles for each gene.
There are two alleles called as the dominant and recessive allele. A dominant allele is defined as a trait that is physically expressed even when combined with a recessive allele, while a recessive allele is defined as a trait that masked by the dominant allele.
The resulting progeny in the [tex]F_2[/tex] generation showed that the recessive trait was produced, tt meaning that there was a 25% chance that the offsprings produced would be short plants and 75% that the progeny produced would be tall. This also applies to seed color if we cross pea plants on the basis of seed color.
Thus, in Mendel's cross, the recessive trait appears in the [tex]F_2[/tex] generation, but not in the [tex]F_1[/tex] generation.

Temperature-sensitive mutations are useful in understanding essential life processes. A temperature-sensitive mutant will be normal at a lower (non-restrictive) temperature; when shifted to a higher (restrictive) temperature, the mutant will reveal its mutant (and potentially deleterious) phenotype. You isolate a plant with a temperature-sensitive mutation in the water-splitting complex. You grow the plant at a non-restrictive temperature, then shift it to its restrictive temperature. The outcome you would most expect to see upon shifting temperature would be
decreased NADPH production.
increased NADPH production.
no change in NADPH production.
decreased sugar production.
no change in sugar production.
increased oxygen production.
Answer:
decreased NADPH production.
decreased sugar production.
Explanation:
The water-splitting complex is associated with PSII and serves as a donor of electrons to the reaction center of PSII. PSII loses its electrons upon trapping of sunlight. These electrons are passed finally to NADP reductase via electron transport chain and PSI. NADP reductase reduces NADP into NADPH. The NADPH formed during the light-dependent phase serves as reducing power in reactions of the Calvin cycle.
A mutation in the water-splitting complex would result in no electron supply to PSII and thereby, reduced production of NADPH. The reduced NADPH production would limit the supply of reducing power for the Calvin cycle and the sugar production would be decreased.
The outcome should be decreased NADPH production and decreased sugar production.
NADPH and sugar:The electrons should be transferred to NADP reductase by electron transport chain and PSI. Due to this, it gets reduced. The reduced NADPH production would limit the supply of reducing power with respect to the Calvin cycle and the sugar production would be decreased.

The greater the mass of tissue in an organ, the greater its need for an adequate blood supply. Which chamber of the heart has the highest probability of being the site of a myocardial infarction?
Left ventricle.
Explanation:
Left ventricle is the chamber of the heart that has to work against the highest resistance. Because it has to pump blood into the systemic circulation. moreover it has a greater muscle mass and is more thicker than the right chambers of the heart.
Thus, the oxygen demand of left ventricle is much more than that of the other three chambers. If by any means the blood supply to the heart is not sufficient to fulfill the oxygen demand of the left ventricular cells then it would result in myocardial infarction commonly termed as heart attack
