Answer:
Herbivorous animals are unable to feed and end up migrating to other regions in search of food.
Explanation:
The tundra is a type of vegetation composed almost exclusively of mosses and lichens. This type of vegetation is found in regions with a polar climate. It is important to note that the tundra has a very fast vegetative cycle. That's because it freezes quickly and can be covered with ice all winter. This ends up modifying the lives of some animals that feed on this vegetation. These animals end up with unavailability of food and need to migrate to others in search of food.

Which organ uses the circulatory system to communicate with cells throughout the body to control the amount of sugar they have available?
Most species of E. Coli are harmless or even helpful forms of bacteria that are found in the human intestine. E. Coli can aid humans in digestion and provide protection from other invading bacteria, but if the bacteria move to the human excretory system, they can replace other naturally occurring bacteria (Lactobaccilli). This can lead to bladder and kidney infections. Researchers found that by replenishing the excretory system with the naturally occurring bacteria, the infection caused by E. Coli is cured. Based on the research, what inference can researchers claim about the effect of bacteria?
Answer:
The inference is that bacteria can be pathogenic or characteristic of the commensal microbiota of different organs.
Explanation:
The human coexists with commensal micro-flora or commensal biota that are in balance and protect it from other pathogenic microorganisms, that is why we constantly live with a group of bacteria that do not generate pathological conditions in our body and even promote the stimulation of the immune response. .
When this balance is broken, pathogenic or opportunistic microorganisms invade, this is how they proliferate and generate infectious diseases that threaten the balance or state of human health.

HELP!! Which of the following is NOT true of protein structure?
A: Proteins' secondary structure is dictated by peptide bonds.
B: Proteins' tertiary structure is dictated by R group bonds.
C: Proteins have quaternary structure when they are arranged together.
The statement that is not true related to the protein structure is option b. Proteins' tertiary structure is dictated by R group bonds.
What is protein structure?It is classified as the three dimensional shape of the protein.
In the tertiary structure it does contain the single polypeptide chain that we called as the backbone or there more than one protein secondary structures
Also, it should not be dictated by R group bonds.
Therefore, we can conclude that the option b is correct.

The growth of the algae came from the air and water in the bottle.
The statement (D) is correct. The growth of the algae came from the air and water in the bottle.
What is an algae?Algae is an informal term for a large and diverse group of photosynthetic eukaryotic organisms. It is a polyphyletic grouping that includes species from multiple distinct clades.
Moreover, algae are photosynthetic creatures. They are neither plant, animal or fungi. Many algae are single celled, however some species are multicellular. Many, but not all of red and brown algae are multicellular.
Therefore, algae are defined as a group of predominantly aquatic, photosynthetic, and nucleus-bearing organisms that lack the true roots, stems, leaves, and specialized multicellular reproductive structures of plants.

Explanation:
Widow's peak is a dominant trait (W). Tongue-rolling is a dominant trait (T). Two people who are heterozygous for both traits (widow's peak, tong-roller) get married and have children. Complete the Punnett square to show the parents the probabilities for each child, then answer the question that follows.
What is the probability that the parents will have a child without a widow's peak and unable to roll his tongue?
Group of answer choices
3/16
9/16
0/16
1/16
Answer:
The correct answers are -
A. 1) WWTt 2) WWTt 3)WwTt 4)wwTT
B. 1/16
Explanation:
We know that each gene have minimum two alleles or forms of the gene one is dominant and the other is recessive. So, it is given that W is dominant trait that represents widow's peak so the recessive allele would be w, similarly for the tongue-rolling trait dominant is T n recessive would be t.
So the dihybrid cross of heterozygous parents for both is shown in the punnet square given which lack few possibilities that can easily be carried out by the gametes mention there that are
1. WWTt by WT and Wt gamets
2. WWTt by WT and Wt
3)WwTt by Wt and wT
4)wwTT by wT and wT
And the possibility of a child without a widow's peak and unable to roll his tongue would be possible only if the alleles are recessive for the both trait which is one out of 16 in punnet square thus the possibility would be - 1/16
