Viruses use the cell receptors to enter the cell.
Option D.
Explanation:
Viruses are the small intracellular pathogens which cannot reproduce on their own. A viral particle can make other virus particles only when it is inside the host. To gain entry inside the host, viral particles interact with the cell receptors of the host through which they are either endocytosed or inject their genetic material inside the host cell.
Once the viral genetic material RNA or DNA is inside the host it takes over the host replication machinery to replicate viral genome and to transcribe the viral proteins to produce more viral particles which rupture the cell and released to invade other cells.

Which statement about the immune system is false?
A. Lymphocytes reduce inflammation,
B. B cells remember specific pathogens.
C. Most white blood cells kill bacteria
D. White blood cells are made in lymph nodes.
Final answer:
The false statement about the immune system is that white blood cells are made in lymph nodes; they are actually produced in the bone marrow. Lymphocytes, such as B cells, are involved in adaptive immune responses, with B cells producing antibodies and memory B cells retaining pathogen information.
Explanation:
The statement about the immune system that is false is:
D. White blood cells are made in lymph nodes.
This statement is incorrect because while lymph nodes are a site where white blood cells can mature and interact with antigens, they are not the primary site of white blood cell production. White blood cells are primarily made in the bone marrow. Lymphocytes, which include B cells and T cells, are the subset of white blood cells that are involved in adaptive immune responses. Plasma B cells produce antibodies to fight against pathogens, and memory B cells retain the information about specific pathogens, enabling a faster and more robust response upon subsequent exposures. Meanwhile, certain white blood cells, such as macrophages, are known for their ability to phagocytize pathogens and produce inflammation-promoting chemicals.

1.) Compare the roles of oxygen and carbon dioxide in autotrophs and heterotrophs. Which organism is an oxygen consumer and carbon dioxide producer? Which organism is an oxygen producer and a carbon dioxide consumer?
Oxygen is used by both autotrophs and heterotrophs to release energy from glucose (as we know, the bonds between organic compounds can be used to release energy) in a process known as cellular respiration. Carbon dioxide, however, is predominantly used in autotrophs to perform photosynthesis because they cannot get their food any other way. The type of organism that is both an oxygen producer and carbon dioxide consumer is an autotroph. This is because they release oxygen during photosynthesis and require carbon dioxide to perform photosynthesis.

1. Two animals are mated. One is homozygous dominant for one character and homozygous
recessive for another. The other animal is heterozygous for both characters. How many
phenotypes are expected in the offspring of this cross?
From a cross of homozygous dominant and homozygous recessive parent lines with heterozygous parents, a 1:1 phenotypic ratio is seen. Two types of phenotypes will form.
What is a dihybrid cross?A dihybrid cross involves two traits. Example: an animal with both genes for height and body coloration is taken . The height is represented as T. T is for tall characters, and t is for short characters. A homozygous dominant character is represented as TT. Homozygous recessiveness is expressed by tt.
Another gene such as body coloration is taken. Black (B) is dominant over white (b). An animal with homozygous dominant is BB. An animal having homozygous recessive is bb.
A parent with homozygous dominant for tall character and homozygous recessive for body colour is represented by TTbb. An animal that is heterozygous for height and body coloration is taken as TtBb.
From the crossing, two phenotypes are derived, such as tall black and tall white. Out of all eight individuals, four are tall black and four are tall white. The phenotypic ratio is 1:1. The cross is explained below.

Answer:
1. bulbs - Onions and garlic reproduce using these
2. corms = Gladiolus and freesia plants have these special stems...
3. Rhizomes - Banana trees and bamboo have these horizontal...
4. Stolons - strawberry plants and Bermuda grass...
5. Tubers - Fleshy, enlarged stems like the potato
Explanation:
Bulbs are made up of layers and layers of modified leaves called scales. These scales provide the nutrition for the growing plant. They have roots at the bottom that anchor the plant.
Corms are similar to the bulb but they are more solid and do not have scales. They are kind of round but with a flat top. As the leaves of the plant grow, the corm shrinks until it is gone. New corm grow from the buds that grow out of the original corm.
Rhizomes are underground stems. They are fleshy and they grow horizontally. Eyes or buds grow around the rhizomes sometimes on the side or on top. Other examples would be irises and ginger.
Stolons are also known as runners. They creep or grow horizontally. They usually grow on the surface, but can also grow underground, just below the surface. These roots grow nodes where each node grows roots which become new plants.
Tubers are fat and round and do not grow horizontally. Instead, they stem out of the eyes and each shoot can become a new plant. You can cut them into pieces to propogate them, as long as there is at least one eye on the replanted piece.
Bulbs, corms, rhizomes, stolons, and tubers are all specialized stems that plants use for asexual propagation, allowing them to produce new individuals without seed formation.
Bulbs: Onions and garlic are examples of plants that reproduce using these. They are underground stems with fleshy scales, where each bud can form new offsets or individual plants.Corms: Corms are used by plants like gladiolus and garlic; they are solid tissue and used for asexual reproduction.Rhizomes: Ginger and iris are examples of plants that produce masses of stems known as rhizomes. These horizontal stems can give rise to multiple plants.Stolons: Also known as runners, strawberry plants produce these stems at the soil surface or below ground, which can give rise to new plants.Tubers: Potatoes are an example of a plant that forms fleshy stem tubers. Each eye in a stem tuber can sprout and grow into a new plant.Color blindness is a recessive trait. The gene for color blindness is on the X-

Where do homologous chromosomes exchange genetic material through crossing over?
A. Chlorophyll B. Centrosomes C. Centromeres D. Chiasma
Answer:
D. Chiasma
Explanation:
In Prophase I of Meiosis, a process called synapsis occurs. Synapsis is the process where homologous chromosomes pair up. Within this process, sister chromatids cross-over at certain points, and these points are called chiasmata. Chiasmata is just the plural of chiasma. In these points, the chromatids intertwine and exchange genetic material through a process called, cross-over.
Some jellyfish have skeletons that are formed by fluid-filled compartments. This fluid resists compression and thus supports the body structure from deforming. Which term describes these skeletons? A. Fluid skeletons B. Hydrostatic skeletons C. Exoskeleton D. Endoskeleton
Answer:
B. Hydrostatic skeletons
Explanation:
Answer:
B. Hydrostatic skeletons
Explanation:
A hydrostatic skeleton is a fluid-filled skeleton that is present in many invertebrates that have soft bodies. Some of the jelly fishes are among them. The hydrostatic skeleton of jelly fishes can be compressed as it is filled with fluid.
However, it can regain the original shape once the pressure is removed. The ability of hydrostatic skeleton to be compressed and to regain the original shape help these jellyfishes to resist deformation of the body.

Answer:
A
Explanation:
Answer:
The correct answer option is A. Force = mass × acceleration
Explanation:
According to the second law of Newton, when an external force is applied on an object, acceleration is produced in the same direction as the external net force.
In other words, we can say that force that is acting on an object is equal to the mass of the object and the acceleration produced by it.
This is represented by the formula:
Force = mass × acceleration

OB. commensalism
parasitism
OD. mutualism
Reset
Next
Answer:
b. commensalism I believe
Answer:
Predation
Explanation:
It is a clear case of predation. Predation is a type of relationship between two organisms in which one organism feeds upon another one causing its the death. The one which feeds upon another one is a predator while other one which is killed is a prey. That means in predation one organism is benefited while another one is harmed. Parasitism and predation are somehow related but the difference between both of them is that in predation, one organism is killed by another one but in parasitism the organism which gets benefited does not kill the host because by doing this it can get benefits from the host for a longer time period.
Other options are wrong. Commensalism is a type of relationship in which one organism is benefited while another one is not affected means derives neither benefit nor harm. So, option B is wrong.
Parasitism is a type of association between two organisms in which one is benefited but another one is harmed without being killed. So option C is incorrect.
Mutualism is a type of association between two organisms in which both of them get benefited out of each other. So option D is also incorrect.
how is the carbon cycle related to global warming ?
Answer:
The carbon cycle controls the amount of carbon dioxide going into the atmosphere by controlling the earth’s temperature and climate. However, the carbon cycle can only regulate the climate and temperature of the earth so much, and since so much CO2 is being produced, the carbon cycle will eventually reach its limit.
The initial greenhouse heating required to maintain water vapor concentrations is provided by carbon dioxide molecules.
What is global warming?Global warming is commonly used to describe human-caused warming of the Earth system, whereas climate change can refer to either natural or anthropogenic change.
The carbon released during a carbon cycle is a greenhouse gas that can lead to global warming if present in excess.

Directions: compare and contrast mitosis and meiosis by answering the questions below.
Mitosis is defined as the phase of the cell cycle where the nucleus of a cell is divided into two nuclei with an equal amount of genetic material in both the daughter nuclei.
What is meiosis?Meiosis is the process in which a single cell divides twice to form four haploid daughter cells.
1. At the beginning of the cell cycle mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis have 1N at the first stage.
2. Mitosis: At the end mitosis only produces 2N diploid cells.
Meiosis : Meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.
3. Mitosis: Daughter cells are diploid.
Meiosis: Haploid (n).
4. Mitosis: yes daughter cells are identical to parent.
Meiosis: there may be little variation in daughter cells. Homologous chromosomes exchange bits of DNA to create genetically unique, hybrid chromosomes destined for each daughter cell.
5. Mitosis: Daughter cells are identical to each other.
Meiosis: there may be little variation in daughter cells.
6. Mitosis: Human somatic cells have 46 chromosomes consisting of two sets of 22 homologous chromosomes.
Meiosis: A pair of nonhomologous seˣ chromosomes. This is the 2n, or diploid state.
7. Mitosis: Once mitosis is complete, the cell has two groups of 46 chromosomes.
Meiosis: chromosome no reduced to half (1N).

Animals have a variety of adaptations, including trachea and gills, which allow this key process to occur. Which provides the molecules necessary for cellular respiration and efficient ATP synthesis?
A. Waste elimination
B. Gas exchange
C. Digestion
D. Nutrient absorption
Answer:
B
Explanation:
Gas exchange provides oxygen that is required for aerobic cellular respiration. Aerobic respiration produces more ATP molecules than anaerobic respiration. This is because oxygen acts as the ultimate proton acceptor (in the Krebs/Citric cycle) in the matrix of the mitochondria to form water as the waste product. This allows a proton motive force to be created in the mitochondria that is harnessed by ATP synthase to produce ATP molecules.
Gas exchange provides the molecules necessary for cellular respiration and efficient ATP synthesis.The correct option is B.
Cellular respiration is the process by which biological fuels are oxidised in the presence of an inorganic electron acceptor, such as oxygen, to drive the bulk production of adenosine triphosphate (ATP), which contains energy. Cellular respiration may be described as a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from nutrients into ATP, and then release waste products.
The reactions involved in respiration are catabolic reactions, which break large molecules into smaller ones, producing large amounts of energy (ATP). Respiration is one of the key ways a cell releases chemical energy to fuel cellular activity.During cellular respiration, there is exchange of gases which takes place.
Thus, option B is correct.

Convert 0.14 kilograms to grams.
grams
Answer:
140 grams
Explanation:
Converting kilograms to grams is very easy, you just need to remember that 1 kilogram has 1000 grams. In this box to do the conversion you only need to multiply the value in kilograms that you have by 1000, as shown below:
0.14 kilograms * 1000 grams = 140 grams.
The conversion of 0.14 kilograms to grams can be written as 140 grams.
We use the conversion factor that 1 kilogram is equivalent to 1000 grammes to convert weights in kilogram to weights in gram.
By multiplying 0.14 by 1000, we can convert 0.14 kilogram to gram:
0.14 kilograms * 1000 grams/kilogram = 140 grams
Gram are frequently used to express lesser amounts of mass because they are a smaller unit of measurement than kilogram.
Thus, 140 grams are therefore equal to 0.14 kilograms. Since there are 1000 grams in a kilograms, the value in kilograms is multiplied by 1000 in order to convert it.
