Answer:
B) In anabolism, larger molecules are made from smaller molecules.
Explanation:
Anabolism is a metabolic process that uses up energy that is produced to build up complex and larger molecules from smaller ones. It is part of the chemical process that takes place in a cell.
For example, photosynthesis is an anabolic process, in which the cell forms larger molecules such as glucose from smaller molecules like water and carbon dioxide, with the use of solar energy.
Option B is true regarding anabolism.
Female honey bees are diploid and male honey bees are haploid. The haploid males produce sperm and can successfully mate with diploid females. Fertilized eggs develop into females and unfertilized eggs develop into males. How does the process of sperm production in male honey bees differ from sperm production in other animals?
a. Male honey bees use meiosis I only, whereas other animals use both phases of meiosis.
b. Male honey bees use meiosis, whereas other animals use mitosis.
c. Male honey bees use mitosis, whereas other animals use meiosis.
d. Male honey bees can use mitosis or meiosis, whereas other animals can only use meiosis.
Answer:
The correct answer is option C.
Explanation:
In most of the male animals the production of sperms takes place through the process of meiosis. Meiosis occurs only in 2n or diploid cells. Thus the most of the animals produce sperm due to their diploid nature.
In male bees the sperm production is different than other animals as it is haploid cell and haploid cells produce sperms through mitosis. In haploid cells mitosis helps in produce more sperms.
Thus, the correct answer is option C.
Choose the true statement. Receptor tyrosine kinases undergo autophosphorylation. G proteins phosphorylate receptor tyrosine kinases. Receptor tyrosine kinases include seven transmembrane segments. Active receptor tyrosine kinases are monomeric proteins.
Answer:
Receptor tyrosine kinases undergo autophosphorylation.
Explanation:
The receptor tyrosine kinases (RTKs) are proteins that undergo dimerization and autophosphorylation after binding with their corresponding ligands, thereby triggering downstream molecular signaling cascades. The RTKs bind with high specificity to ligands including growth factors, hormones and cytokines. In human cells, there are 58 types of RTKs proteins that function to regulate developmental pathways, and their dysfunctions have been associated with cancer progression.

The instructions for making proteins are coded in the (cytoplasm / DNA / endoplasmic reticulum / nucleus) of a cell. In a eukaryotic cell, these instructions are located in the (cytoplasm / DNA / endoplasmic reticulum / nucleus).
Answer:
The instructions for making proteins are coded in the (cytoplasm / DNA / endoplasmic reticulum / nucleus) of a cell. In a eukaryotic cell, these instructions are located in the (cytoplasm / DNA / endoplasmic reticulum / nucleus).
Explanation:
The genetic code is contained in DNA, or deoxyribonucleic acid. This is usually the same among most organisms, save some RNA viruses. But in eukaryotes, the DNA is in the nucleus, whereas in prokaryotes the DNA is in the "nucleoid region", or a twisted up section near the middle of the cell.
The instructions for making proteins are coded in the DNA of a cell. In a eukaryotic cell, these instructions are located in the nucleus.
What is DNA?Deoxyribonucleic acid is a polymer made up of two polynucleotide chains that coil around each other to form a double helix that contains genetic instructions for the development, functioning, growth.
it is also involved in reproduction of all known organisms and viruses. Nucleic acids include DNA and ribonucleic acid.
The information molecule is DNA. It stores instructions for the production of larger molecules known as proteins.
These instructions are stored in the nucleus of each of your cells and are distributed across 46 long structures known as chromosomes.
These chromosomes are composed of thousands of shorter DNA segments known as genes.
DNA is a linear molecule made up of four different types of smaller chemical molecules known as nitrogenous bases.
Thus, DNA is involved in coding protein and is usually located in nucleus.

A cell has two pairs of submetacentric chromosomes, which we will call chromosomes IA, IB, IIA, and IIB (chromosomes IA and I B are homologs, and chromosomes IIA and IIB are homologs). Allele M is located on the long arm of chromosome IA and allele m is located at the same position on chromosome IB. Allele P is located on the short arm of chromosome IA, and allele p is located at the same position on chromosome IB. Allele R is located on chromosome IIA and allele r is located at the same position on chromosome IIB.
A. Draw these chromosomes, identifying alleles M, m, P, p, R, and r as they would appear in metaphase I of meiosis. Assume there is no crossing over.
B. Taking into consideration the random separation of chromosomes in anaphase I, draw the possible types of gametes that might result from this cell’s undergoing meiosis. Assume that there is no crossing over.

Answer:
Hybrid incompatibility has a genetic basis both in plants and animals
Explanation:
In plants, hybrid incompatibility may be associated with different factors including, for example, mismatch recognition in chromosomal pairing, changes in the ploidy level, homozygous lethal alleles, epigenetic-associated factors, postzygotic hybrid incompatibility, etc.
Hybrid incompatibility is recognized to promote reproductive isolating barriers between species, thereby understanding into the genetic basis of this phenomenon may result useful to understand the evolutionary forces that are associated with speciation.
You can reverse the hybrid incompatibility by changing the ploidy level, since it ensures a correct chromosome pairing during the cell division. You can use colchicine, it is an antimitotic agent that is widely used to duplicate the ploidy level.

HOPE IT HELPS :)
PLEASE MARK IT TH BRAINLIEST!
Cancer is a disease in which some cells lose their ability to control rate of division. The correct option is C.
What is cancer?Cancer is the body's unchecked proliferation of aberrant cells. When the body's natural control system malfunctions, cancer might emerge.
Instead of dying, old cells proliferate uncontrollably to produce new, aberrant cells. These excess cells could aggregate into a tissue mass known as a tumour.
Genes, the fundamental building blocks of inheritance, can change in ways that result in cancer.
Chromosomes are long, tightly packed DNA strands where genes are organised. Since genes that determine how our cells behave, particularly how they grow and divide, are altered, cancer is a genetic disease.
Thus, the correct option is C.

The graph below compares the rates of reaction of a burning candle and an exploding firework.
Comparing Chemical Reactions
A graph has time on the horizontal axis and concentration of reactants on the vertical axis. For an exploding firework, the concentration starts high, increases slightly and then decreases rapidly. For a burning candle the concentration starts high, increases more than the firework, and then decreases rapidly. The concentration for the burning candle is higher than the firework at all timepoints.
What can you conclude from the graph?
The reaction that causes a firework to explode requires less energy to start, and occurs more rapidly than the reaction that causes a candle to burn.
The reaction that causes a firework to explode requires less energy to start, and occurs less rapidly than the reaction that causes a candle to burn.
The reaction that causes a firework to explode requires more energy to start, and occurs less rapidly than the reaction that causes a candle to burn.
The reaction that causes a firework to explode requires more energy to start, and occurs more rapidly than the reaction that causes a candle to burn.
Answer:
The reaction that causes a firework to explode requires less energy to start, and occurs more rapidly than the reaction that causes a candle to burn.
Explanation:
The speed of a chemical reaction and the amount of energy required for this reaction is directly linked to the concentration of reagents present in the system. With that, we can say that the higher the concentration of reagents, the faster the chemical reaction will be due to the greater probability of collision between its molecules.
Although the reaction that causes a candle to burn has more reactants than the reaction that causes the fireworks to explode, the latter requires less energy to start. This makes the molecules of the reagents stir faster and collide more efficiently, making the reaction happen much faster.
In summary, the reaction that causes a firework to explode requires less energy to start and occurs more quickly than the reaction that causes a candle to burn.
The reaction that causes a firework to explode requires more energy to start, and occurs more rapidly than the reaction that causes a candle to burn.
The rate of reaction refers to the ease with which reactants are converted to products. The higher the rate of reaction, the faster reactants are converted into products.
The activation energy is the energy required for reactants to be converted into products. It is an energy barrier that separates reactants and products.
From the description of the graphs, we are told that the reaction that causes the explosion of firework starts at high concentration, initially increases slightly then decreases rapidly. The fact that it initially increased slightly before decreasing rapidly implies that the high energy required for the reaction to start is high.
On the other hand, the reaction for the candle to burn starts at high concentration, increases more than the firework, and then decreases rapidly because the reaction requires a lesser energy to commence than the reaction for the burning of candle.
