Type of cell division that is occurring in the cell in the diagram
Answer:
There is no diagram but the cell division happens in stages. PMAT is a way to remember them. prophase, metaphase, anaphase, and telophase. This all takes place in Mitosis. Mitosis is the division of cells to make more *identical* cells, (skin cells, stomach cells). But Miosis is the making and division of sperm cells *not Identical* (sperm, and egg cells) are made in this phase.
1. Suppose you want to design and build a house. How would you communicate your design plans with the construction crew that would work on the house?
2. Cells build large, complicated molecules, such as proteins. What do you think cells use as their "design plans" for proteins?
Answer:
The correct answer is -
1. blueprints.
2. cells use DNA as their design plans
Explanation:
Blueprint is a representative drawing of an engineering plan that helps in understanding how and where the desired to construct on the house. It helps in communicating what work should be done in the house. It helps in visualizing how the end product should be.
In cells, the design plan is DNA that encodes all the information in a specific nitrogenous base sequence in order to produce specific functions and produce all the proteins

What is extinction ?
Answer:
The term extinction's dictionary meaning, is the process of when a species, plant, or any other term for animal family, goes extinct. In more, basic terms, it means when a certain species of animal dies out completely.
This can happen due to several reasons, some being massive natural disasters. Others die out due to an unknown predator entering an ecosystem in which it doesn't belong, therefore disbalancing it.
Examples of extinct animals are Dinosaurs, but their exact reason for going extinct is unkown, there are only theories.
There are also many animals in danger of going extinct, for example Bees.

name a disorder that is a result of shortage of proteins in children
Answer:
A disorder that is a result of shortage of proteins in children is Kwashiorkor
Explanation:
Kwashiorkor is a severe form of malnutrition. It's most common in some developing regions where babies and children do not get enough protein or other essential nutrients in their diet. The main sign of kwashiorkor is too much fluid in the body's tissues, which causes swelling under the skin (oedema). (Source: Kwashiorkor - NHS)
Hopefully this helps.
Kwashiorkor is a serious condition that can happen when a person does not consume enough protein. Severe protein deficiency can lead to fluid retention, which can make the stomach look bloated.
Kwashiorkor is most common in children, especially if they do not have access to adequate nutrition soon after they stop breastfeeding. If a child experiences kwashiorkor, they need immediate medical attention.
Other terms for kwashiorkor include:
protein malnutrition
malignant malnutrition
protein-calorie malnutrition

Answer:
In the human adult, the bone marrow produces all of the red blood cells, 60–70 percent of the white cells (i.e., the granulocytes), and all of the platelets. The lymphatic tissues, particularly the thymus, the spleen, and the lymph nodes, produce the lymphocytes (comprising 20–30 percent of the white cells).
Answer:
E
Explanation:
Red blood cells, most white blood cells, and platelets are produced in the bone marrow, the soft fatty tissue inside bone cavities. Two types of white blood cells, T and B cells (lymphocytes), are also produced in the lymph nodes and spleen, and T cells are produced and mature in the thymus gland.

Answer:
Metallic structure with black colour body.
Explanation:
The substance has metallic structure and black colour body will have greatest temperature among other substances because metallic structure and black colour of body heat up very quickly. Metals have free electrons which make it the best conductor of electricity and heat while on the other hand, black colour is a good absorbent which absorb heat very quickly so that's why we can say that metallic solids are the substance that have the greatest temperature.

which water pollutants can lead to excessive growth of water weeds
Answer: Water pollution also affects the ecosystem – it can cause a phenomenon called eutrophication. This can cause fish and other aquatic organisms to die. Toxic elements dissolved in water can make their way to humans through fish or other aquatic organisms.
https://byjus.com/biology/effects-of-water-pollution/
Explanation:
Answer:
Excessive nutrients (nitrates) from fertilisers are flushed from the land into rivers by rainwater. Oxygen levels reach such a low point that fish and other organisms suffocate. These nutrients cause increased aquatic plant growth of algae and other plants.

Given the following cross TtYyRr x TtyyRr (T = tall; t = short Y = yellow; y = green R = round; r = wrinkled), what proportion of offspring would be expected to be short plants with round, green seeds. Write your answer as a reduced fraction - e.g. 1/2 proportion is
Answer:
3/32 ttyyR-
Explanation:
Cross: Tall, Yellow, Rounded individuals with a tall, green, rounded individual
Parentals) TtYyRr x TtyyRr
Gametes) TYR, TyR, TYr, Tyr, tYR, tyR, tYr, tyr (Parent one)
TyR, TyR, Tyr, Tyr, tyR, tyR, tyr, tyr (Parent two)
We need to know what proportion of offspring is expected to be short plants with round, green seeds. So we need to identify the gametes for these traits. The genotypes are:
Shot → ttRound → RR or RrGreen → yy⇒ Parent one can provide gametes tyR and tyr
⇒ Parent two can provide gametes tyR and tyr
(1/8 tyR x 2/8 tyR) + (1/8 tyR x 2/8 tyr) + (1/8 tyr x 2/8 tyR) =
2/64 ttyyRR + 2/64 ttyyRr + 2/64 ttyyRr =
1/32 ttyyRR + 2/32 ttyyRr =
3/32 ttyyR-
The branch of science which deals with the gene and inheritance is called biology.
The correct answer is 3/32.

Describe the metabolic pathways in the monarch butterfly that take advantage of milkweed nectar to convert it into an energy currency.
Answer:
Metabolic pathways in monarch butterflies are as follows:
GlycolysisKreb's cycleOxidative phosphorylationExplanation:
They convert sugar which they obtain from nectar into fats that they store as source of energy. Monarch have a little layer of fatty tissues which aid in conversion of Sugar in to fat.
They consume the stored fat during reproduction. A lot of fat is eventually converted to eggs and some of it is used to provide energy just to sustain the reproductive butterflies.
During winter season, when their metabolic is low they consume energy by converting stored fat into sugar called Trehalose. The conversion of fat also releases little water which help them to survive during winter.
1) Glycolysis:
Glucose is phosphorylated by hexokinase enzyme to give glucose-6phosphate. This glucose-6-phosphate enters into glycolysis and is broken down into two molecules of pyruvate in a series of ten reactions. During glycolysis net two molecules of ATP are synthesised per glucose molecule. Moreover, two molecules of NADH+H+ are also synthesised. In aerobic organisms like monarch butterfly the pyruvate is again oxidised to give acetyl-CoA in the mitochondria. The enzyme responsible for this oxidation is Pyruvate Dehydrogenase Complex. This reaction occurs in the mitochondrial matrix. Here one CO2 molecule is removed from the pyruvate and one NADH is produced.
2. Kreb's Cycle:
The acetyl-CoA formed enters into the Kreb's cycle by condensing with oxaloacetate. In Kreb's cycle acetyl-CoA is completely oxidised to give carbon dioxide in eight enzymatic reactions. During Kreb's cycle NADH, FADH2 and one molecule of GTP is produced and oxaloacetate is regenerated to continue the cycle.
3. Oxidative Phosphorylation:
The NADH produced in the glycolysis and Krebs cycle and FADH2 produced during Krebs cycle are now oxidised to generate proton gradient across the inner mitochondrial membrane. This gradient is generated when the electrons from the reduced NADH and FADH2 are transported in the electron transport chain(ETC), and are finally accepted by the oxygen.
When the electrons are picked up by the complexes of the ETC they pick protons from the matrix. When the electrons are transferred to next complex the protons are transferred to the inter-membrane space. In this way a proton gradient is generated across the innner membrane of the mitochondria.
This proton gradient is used by the complex V of the ETC. This complex is the enzyme ATP Synthase. This enzyme complex is located in the inner mitochondrial membrane. When the protons flow back from the inter-membrane space into the matrix along the concentration gradient , they move through the channel in the ATP Synthase Complex. When these protons flow through this complex it catalyzes the phosphorylation of ADP to give ATP, the energy currency.
The fructose component of the sucrose is first converted into glycogen and then broken down to give glucose-1-phosphate, which enters into glycolysis.
Sucrose cannot enter the pathway of glycolysis as such. It is first hydrolysed to glucose and fructose as described above along with the path way.

The enzyme choline acetyltransferase catalyzes the reaction between acetyl-CoA and choline resulting in the formation of the neurotransmitter acetylcholine. This enzyme is produced within the cell body of neurons, but the synthesis of acetylcholine occurs within the axon terminals. What best describes the axonal transport mechanism associated with this process?
Answer: Anterograde direction.
Explanation:
Choline acetyltransferase is an enzyme made in the body of a neuron and that needs to be transferred to the axon terminal to perform its function. Its function is to bind acetyl-CoA to choline to form the neurotransmitter acetylcholine.
The movement toward the cell body is called retrograde transport and the movement toward the synapse is called anterograde transport. So, since it is produced in the body of the cell and it has to go to the axon terminals, the choline acetyltransferase is transported in the anterograde direction.
This type of transport is responsible for the movement of organelles such as mitochondria, lipids, synaptic vesicles, proteins from a neuron cell body through the cytoplasm of its axon called the axoplasm. Because axons can sometimes be meters long, neurons cannot rely on diffusion to carry products to the end of their axons. Dynein is a motor protein involved in this retrograde axonal transport. Its light chains bind cargo, and its globular head regions bind the microtubule, "moving forward" along it.
