What is parturtion and lactation???
Answer:
It is the process of production of milk by the mammary glands at the end of pregnancy. The milk produced initially by the glands is called colostrum. This milk is crucial for the baby as it provides the child with the initial immunity. This was a brief explanation of pregnancy, parturition, and lactation.

In people-eaters, purple is dominant to white. A true-breeding white mutant is mated with a different true-breeding white mutant. All of the F1 are purple. When the purple F1 offspring mate with each other, their offspring occur in the ratio of 9 purple : 7 white. Which phenomenon explains the purple F1 offspring
Answer:
The correct answer is - Complementation.
Explanation:
In this pattern of inheritance, there are two same type mutants that are crossed that are true-breeding white with another true-breeding white mutant. Let these mutants are CCpp and the other be ccPP.
All the f1 offspring produced are found to be purple in color as offspring will be CcPp. The products of both gene C and P required for the purple pigment to be expressed these genes complement each other and the absence of any of gene results in lack of the dominant phenotype.
Very rapid (i.e. in 1-2 seconds) responses to maintain normal blood pressure during a sudden decrease in blood volume by hemorrhage can be initiated by Group of answer choices secretion of ADH from the posterior pituitary. vasoconstriction of capillaries. baroreceptors in the aortic arch. vasodilation of precapillary sphincters. Two of the answers are correct.
Answer:
vasoconstriction of capillaries.
baroreceptors in the aortic arch.
Explanation:
Vasoconstriction of capillaries and baroreceptors in the aortic arch are the two quick responses of body to maintain normal blood pressure during hemorrhage. Vasoconstriction is very necessary for lowering acute blood loss during hemorrhage means escape of blood from a ruptured blood vessel as well as maintain body heat and arterial pressure. The function of baroreceptors is to respond to the change in the tension of the arterial wall when blood pressure changes.
g Classify the statements as describing deoxyribonucleic acid (DNA) or ribonucleic acid (RNA). DNA RNA is a single molecule that can be over 10,000,000 nucleotides long is usually double stranded includes the base thymine can be translated into a protein is the genome for prokaryotic organisms is usually single stranded includes ribose sugar is a single molecule that can form a complex secondary structure
Answer:
DNA:
- is a single molecule that can be over 10,000,000 nucleotides long
- is usually double stranded
- includes the base thymine
- is the genome for prokaryotic organisms
RNA:
- can be translated into a protein
- is usually single stranded
- includes ribose sugar
- is a single molecule that can form a complex secondary structure
Explanation:
Deoxyribonucleic acid (DNA) is the hereditary genetic material of both prokaryotic and eukaryotic organisms, while RNA is the genetic material of many viruses. DNA is a double helix molecule composed of four types of nucleotides: a nitrogenous base (Adenine, Thymine, Cytosine and Guanine), a five-carbon sugar (i.e., deoxyribose), and a phosphate group. On the other hand, RNA is usually a single-stranded molecule whose nucleotides contain ribose sugars and Uracil bases replace Thymine bases. During translation, a type of RNA molecule referred to as messenger RNA (mRNA) is used as template to direct the synthesis of a polypeptide chain (protein). This RNA molecule can fold to form stable double-stranded RNA hairpins (i.e., secondary structures).

You have isolated a bacterium from a contaminated river but you are unable to culture it in the laboratory. Which method could you use to identify the organism
Answer:
DNA sequencing
Explanation:
DNA sequencing is the method which can be used in order to identify the bacterium that was isolated from the contaminated river. DNA sequencing is the process in which the sequence of nucleotides is determined that is present within a DNA molecule. For identifying the bacterium, the sample of bacteria is collected. After sample collection is completed, genomic DNA is extracted from the bacteria and DNA sequencing will be done of that bacteria.

3. How do nutrients and other materials move in fungi?
Answer:
Nutrients and other materials from the environment are absorbed through mycelia. The branching mycelia have a high surface-area-to-volume ratio which allows the absorption of nutrients to be more efficient. Fungi may even digest nutrients by releasing enzymes into the environment.
Explanation:
I have a strange feeling that this isn't the answer you were looking for.
Yeah Why is global warming a
significant environmental
stressor
Answer:
it can destroy animal habitat like the penguin of polar bear. plus it causes droughts and severe storms to happen. also I've heard that in the warmest places you can catch diseases more easily.

The stage of mitosis where the chromosomes line up
Answer:
Metaphase
Explanation:
Chromosomes line up at the metaphase plate, under strain from the mitotic shaft. The two sister chromatids of every chromosome are caught by microtubules from inverse shaft posts. In metaphase, the shaft has caught every one of the chromosomes and arranged them at the center of the cell, prepared to separate.
Answer:
It is metaphase.
Explanation:
In metaphase (a), the microtubules of the spindle (white) have attached and the chromosomes have lined up on the metaphase plate. During anaphase (b), the sister chromatids are pulled apart and move toward opposite poles of the cell.

How does halving the hawk population affect the grass, rabbits, and snakes
Answer:
Rabbits and snakes increase in number but grasses decrease in number.
Explanation:
If the population of hawk is decreases to half then the population of rabbits and snakes increases because hawk feeds on rabbits and snakes. The amount of grasses also decreases due to increase in the population of rabbits which feeds on these grasses. Hawks controls the population of rabbits and snakes when these hawks are decrease in number then the ecosystem will destabilize by increasing number of rabbits and as a result vegetative cover decreases quickly.
