Answer:
Birds have a two part stomach, a glandular portion known as the proventriculus and a muscular portion known as the gizzard. Hydrochloric acid, mucus and a digestive enzyme, pepsin, are secreted by specialized cells in the proventriculus and starts the process of breaking down the structure of the food material.

Explanation:
plankton are eaten by pretty much everything as they are so small. they also get food through photosynthesis therefore they do not eat any other animals. i am pretty certain krill eat them but i dont know
Answer:
Plankton is likely to be in the lowest trophic level of an ocean food chain.
Explanation:
Plankton are the diverse collection of organisms found in water that are unable to propel themselves against a current. The individual organisms constituting plankton are called plankters. In the ocean, they provide a crucial source of food to many small and large aquatic organisms, such as bivalves, fish and whales.

Mary has always been very healthy. Even though all her friends have been verysick with the flu this year, she does not feel like she
needs to get a flu shot. Mary has what perception towards risk?
a. degree of control
b. instant gratification
c. optimism bias
d. catastrophe
Optimism bias is the perception towards risk that Mary has.
The optimistic bias is a term to refer to the human tendency to see the future positively and better compared to the past and the present. The optimistic bias includes the tendency to underestimate the possibility of negative things happening, such as illness, car accidents, and unemployment.
According to the above, Maria has a perception of optimistic bias because she is underestimating the possibility of getting sick even though all of her friends have gotten sick. This may be reinforced by the fact that she is in good health and that is why she does not think it is necessary to get vaccinated.
Additionally, the degree of control, instant gratification, and catastrophe options are not correct options because they are types of perception different from optimistic bias.

Change the following sequence (GGAUUC) to show:
a. Substitution
b. Insertion
c. Deletion
Answer:
Given the sequence of bases of the RNA GGAUUC, the possible mutations would be:
a. Substitution: GGAUUC → GGAAUC
b. Insertion: GGAUUC → GGACCUUC
c. Deletion: GGAUUC → GG_UC
Explanation:
The fragment observed is recognized as RNA, due to the presence of uracil (U). The mutations observed in this fragment are derived from a mutated DNA molecule, which was transcribed into mRNA
Substitution is a molecular mutation that occurs when one nitrogenous base is changed to another in the DNA sequence. GGAUUC → GGAAUC Mutated DNA: CCTTAGInsertion occurs when entire bases or segments are added to the original genetic material, resulting in a longer molecule. GGAUUC → GGACCUUC Mutated DNA: CCTGGAAGDeletion is a type of mutation where genetic material is lost, which can be nitrogenous bases or segments of the molecule. GGAUUC → GG_UC Mutated DNA: CC_AGEach of these mutations can have an effect on protein synthesis, affecting the structure or function of the final protein.

Which of the following is false regarding the protein pepsin?
A. Pepsin hydrolyzes peptide bonds.
B. Pepsin is a type of protease.
C. Pepsinogen is the active form of pepsin.
D. Pepsinogen self-cleaves at the pH found in the stomach.
E. None of the above are false.
Answer:
C. Pepsinogen is the active form of pepsin.
Explanation:
Pepsin is a gastric protease belonging to the aspartic proteinase family which breaks down polypeptide chains into smaller peptides by hydrolyzing peptide bonds. Pepsin is found in the gastric juice where it digests proteins from foods together with other digestive enzymes and hydrochloric acid. Moreover, pepsinogen is a precursor of pepsin which is secreted by the gastric chief cells of the human stomach and then is converted into pepsin (its active form) by hydrochloric acid.

What does an increased pulse rate indicate about the heart rate
Answer:
A high heart rate can also mean the heart muscle is weakened by a virus or some other problem that forces it to beat more often to pump enough blood to the rest of the body. Usually, though, a high heart beat is not due to heart disease, because a wide variety of noncardiac factors can speed the heart rate.
Coat color in cats is a codominant trait and is located on the X chromosome. Cats can be black, orange, or calico. A calico cat has black and orange splotches. In order to be calico, the cat must have an allele for the black color as well as an allele for the orange color. Also located on the X chromosome of a cat is a gene that codes for deafness. The gene is recessive. A black female cat that is heterozygous for deafness (Dd) is crossed with a male orange cat that is not deaf. Show the cross. What are the phenotypes of the offspring and in what proportion? (Hint: Place two superscript letters on the X chromosome in your cross.)

A change in DNA could alter the amino acid order which will affect the folding of the protein, and therefore it's function. True or false
Answer:
The gene, or sequence of DNA, ultimately determines the unique sequence of amino acids in each peptide chain. A change in nucleotide sequence of the gene's coding region may lead to a different amino acid being added to the growing polypeptide chain, causing a change in protein structure and therefore function
Explanation:
The statement "a change in DNA could alter the amino acid order which will affect the folding of the protein, and therefore its function" is definitely true.
What are amino acids?Amino acids may be defined as the monomers of the building blocks of proteins. These compounds contain carbon, hydrogen, nitrogen, and oxygen. Amino acids are generally composed of an amino group, a carboxyl group, a hydrogen atom, and a distinctive side chain.
The sequence of DNA is made on the foundation of amino acids along with nucleotides. These sequences govern the special function with respect to their coding and folding. Each sequence specifies a particular protein.
A little change or alteration in these sequences may direct the formation of different amino acids. This completely changes the folding of the protein. This means that the physiology of the protein structure change which also affects its function.
Therefore, the statement "a change in DNA could alter the amino acid order which will affect the folding of the protein, and therefore its function" is definitely true.

Answer: Magnolia is a large genus of about 210 flowering plant species in the subfamily Magnolioideae of the family Magnoliaceae. It is named after French botanist Pierre Magnol. Magnolia is an ancient genus. Appearing before bees did, the flowers are theorized to have evolved to encourage pollination by beetles. To avoid damage from pollinating beetles, the carpels of Magnolia flowers are extremely tough. Fossilized specimens of M. acuminata have been found dating to 20 million years ago, and of plants identifiably belonging to the Magnoliaceae date to 95 million years ago. Another aspect of Magnolia considered to represent an ancestral state is that the flower bud is enclosed in a bract rather than in sepals; the perianth parts are undifferentiated and called tepals rather than distinct sepals and petals. Magnolia shares the tepal characteristic with several other flowering plants near the base of the flowering plant lineage such as Amborella and Nymphaea.

A peony plant with straight stamens and red petals was crossed with another plant having straight stamens and streaky petals. The seeds were collected and germinated and the following offspring were obtained 62 straight stamens with red petals 59 straight stamens, streaky petals 18 incurved stamens, red petals 22 incurved stamens, streaky petals a) Which alleles in each pair are dominant
Answer:
Explanation:
From the given information.
Let the Straight stamens be S;
The incurved stamens be s;
The red petals be R; and
The streaky petals be r
The genotype of the parental plants are Straight stamens, red petals (SsRr) and Straight stamens, streaky petals)
So if SsRr and Ssrr crossed together, Then we have the following:
If SsRr self crossed, we have the following traits = SR Sr sR sr; &
Ssrr = Sr Sr sr sr
Then, the dihybrid cross is:
SR Sr sR sr
Sr SSRr SSrr SsRr Ssrr
Sr SSRr SSrr SsRr Ssrr
sr SsRr Ssrr ssRr ssrr
sr SsRr Ssrr ssRr ssrr
P(Straight stamens, red petals) = 8/16
P(Straight stamens, streaky petals) = 6/16
P(Incurved stamens, red petals ) = 2/16
P(Incurved stamens, streaky stamens) = 2/16
