What is homeostasis ?It is a physiological process where body to maintain the internal environment in response to changes in outer external environment.
Internal environment means the interstitial fluids while external environment refers to the environment in which organisms live.
Any fluctuation in homeostasis leads to death or a disease of an organism, called as homeostatic imbalance.
The diseases include diabetes, dehydration, hypoglycemia, hyperglycemia, gout etc.
The controlling factors of homeostasis are stimulus can be any physical, chemical or environmental factors leads to deviation of normal body’s environment
Receptor receives the stimulus and pass to the control center like neuron.
Regulator can control coordinator center receives and processes information from the receptor like Hypothalamus.

1. Which of the following is true about eating?
Calcium is not very important.
It is not important to eat before you exercise.
Carbohydrates are not good for you.
It's important to eat the right kinds of food before you exercise.
Answer:
It's important to eat the right kinds of food before you exercise.
Explanation:
Since:
-Carbs help fuel your brain, kidneys, heart muscles, and central nervous system.
-Eating or drinking before exercise can improve workout performance and may allow you to work out for a longer time or at a higher intensity. If you don't eat, you might feel sluggish or lightheaded when you exercise.
-Calcium is a mineral most often associated with healthy bones and teeth, although it also plays an important role in blood clotting, helping muscles to contract, and regulating normal heart rhythms and nerve functions.
all the other options are false

mRNA moves out of the nucleus into the cytoplasm and attaches to another RNA called rRNA, a protein assembly site referred to as the ribosome.
What is Ribosome?This is referred to an organelle which is responsible for protein synthesis in cells.
The mRNA is used as a template for the rRNA to attach at this point to aid in protein translation and production. rRNA ensures that the appropriate amino acids are added and also form part of the ribosome which are involved in catalysis of the reaction.

from about 450 to 300 million years ago, ______ dominated earth's vegetation, and then about 300 million years ago, ______ began to become more prominent.
From about 450 to 300 million years ago, bryophytes dominated the earth's vegetation, and then about 300 million years ago, gymnosperms began to become more prominent.
Evolution of plantsAbout 450 to 300 million years ago, most of the plants as we currently have them are yet to evolve according to evolutionists.
Instead, seedless vascular plants such as bryophytes were around. Many years after, these seedless plants evolved into vascular plants with seeds that are not enclosed in fruits.
Vascular plants with seeds but without fruits are known as gymnosperms. Plants whose seeds are enclosed in fruits, angiosperms, evolved thereafter.

Explanation:
Why do calculations of recombination frequencies between loci that are far apart on chromosomes underestimate the true genetic distance between the loci?.
This is the complete question
A. Recombination frequencies cannot exceed 50% and asymptotically approach 50% as the distance between genes increases because only one crossover can occur per chromosome. B. As the distance between loci increases, some multiple crossovers go undetected such that the relationship between recombination frequency and map distance ceases to be linear. C.Loci that are far apart on a chromosome often recombine to produce combinations of alleles that result in a lethal phenotype and such recombinants are not recovered or identified. D. Loci that are far apart on a chromosome are often susceptible to a form of chromatic interference that results in reduced crossing over, and this interference does not occur for loci that are closer together. E. If two crossovers occur between two loci, then only nonrecombinant gametes are produced; therefore, recombination frequencies actually begin to decrease for more distant pairs of genes.
As the distance between loci increases, some multiple crossovers go undetected such that the relationship between recombination frequency and map distance ceases to be linear. Thus, option "B" is correct.
How, explain your answer briefly?When calculating recombination frequencies, and hence, map distances, we might notice that these distances are not completely additive. They might vary. For example, let us say that we have three genes, A, B, and C, in that order. We calculated that the distance between A and B equals 5.9 MU and that B and C are 19.5 MU apart. According to this, we might say that the total distance between A and C is 25.4 MU (5.9 + 19.5). However, after a two-point calculation between A and C, the value equals 23.7 MU.
The recombination frequency between these two genes located in the extremes and far apart underestimates the actual genetic distances between them because there might occur other crossing-overs that were not detected. This is when calculating the distance between A and C, we probably will not detect the occurrence of a double recombinant between them, and hence, we might sub-estimate the real distance.
The relationship between the actual map distance (number of crossing overs) and the recombination frequency between two loci, is not lineal. The farther apart are the two genes, the worse is the distance estimation.
Thus, option "B" is correct.

What is reproduction?Reproduction is defined as birthing is the process by which a living thing produces offspring. To reproduce is to reproduce. It is a biological procedure by which an organism creates a physiologically identical progeny. Generation after generation, reproduction makes possible and ensures the survival of species.
The phases of the cell cycle are G1, S, G2, and mitosis. In gap 1, the cell expands in size and copies the DNA during the synthesis phase. The cell goes through preliminary modifications in the gap 2 phase. The real division takes place during the mitotic phase, when the cell multiplies and grows in quantity to replace the burned victim's old and dead cells. It encourages the wounded area's growth and healing.
