Describe and explain how blood in the right ventricle travels to the left atrium


pls give me a awnser even if it’s just a sentence

Answers

Explanation:

Deoxygenated blood enters the right atrium passes through the right ventricle and then goes the lungs through the pulmonary artery.

It becomes oxygenated and enters the left atrium through the pulmonary vein

When the right ventricle contracts, blood is forced through the pulmonary semilunar valve into the pulmonary artery. Then it travels to the lungs. In the lungs, the blood receives oxygen then leaves through the pulmonary veins. It returns to the heart and enters the left atrium.

How to write a discussion on macromolecules in a lab report

Answers

The most common macromolecules found in living organisms are lipids, carbohydrates, proteins and nucleic acids. Briefly, the meaning of macromolecules is that they normally contain two or more molecules in them and their main functions are to store energy, information and much more. Most foods are known to be combinations of macromolecules. While some of these compounds can be detected by taste tests, many cannot. Scientists then use certain tests to determine the presence of macromolecules. In doing the lab, one was able to determine the characteristics of the given solutions, containing different macromolecules, whilst doing the multiple tests.

Compared to the distances between the planets of our solar system, the distances between stars are usually

Hoof type in pigs is determined by a gene with the dominant allele (H) resulting in a fused hoof while the recessive allele (h) gives rise to a cloven hoof. The color pattern of the animal’s coat is determined by a dominant allele (B) that results in a belted pattern or a recessive allele (b) that leads to a solid color. Give the possible genotypes and phenotypes of the progeny resulting from crossing a HhBB male with a HhBb female.

In pole beans, the color of the bean is controlled by a gene with the dominant Red (R) allele and pale-green (r) allele is recessive. The mode of growth, either climbing or bush is controlled by another gene on another set of homologous chromosomes. The climbing (B) mode of growth is dominant over bush (b). A red bush plant was crossed with a pale-green climbing plant. Of the offspring there were approximately equal numbers of red, climbing; red, bush; pale-green, climbing; and pale-green bush. Give the genotypes of the parents and offspring.

Answers

Answer:

Problem 1: Give the possible genotypes and phenotypes of the progeny

F1) Genotypes:

    2/16 = 1/8 of the progeny will be HHBB     2/16 = 1/8 of the progeny will be HHBb     2/16 = 1/8 of the progeny will be HhBB     2/16 = 1/8 of the progeny will be HhBb     2/16 = 1/8 of the progeny will be HhBB     2/16 = 1/8 of the progeny will be HhBb     2/16 = 1/8 of the progeny will be hhBB     2/16 = 1/8 of the progeny will be hhBb

    Phenotypes:

12/16 = 3/4 of the progeny will be fuse-hoofed and belt-colored, H-B-4/16 = 1/4 of the progeny will be cloven-hoofed and belt-colored, hhB-

Which of the following will most likely decrease genetic diversity?

А increased reproduction

B selective breeding

C mutations

D immigration

Answers

i pretty sure the answer would be the second option, or answer B

Selective breeding dangers reduced genetic diversity can result in certain insects or diseases attacking, which could be quite devastating.  Thus, option B is correct.

What is the cause of selective breeding in genetic diversity?

Selective breeding can contribute to a large reduction in the genetic diversity of farmed populations, endangering long-term evolutionary progress and limiting populations' ability to adjust to environmental changes.

Unknowingly selecting uncommon illness genes as part of a desirable characteristic might cause difficulties with particular organisms, such as the high prevalence of deafness in Dalmatian dogs.

Genetic diversity is typically reduced by selective breeding, since only a few individuals are employed to produce enormous numbers of offspring. The population's survivability may be impacted by this.

Therefore, selective breeding will most likely decrease genetic diversity.

During protein synthesis, what does mRNA do?
A It strings together two complements RNA strands
B It constructs proteins out of random amino acids
It strings together two complementary DNA strands
D It delivers DNA's instructions for making proteins to the ribosome

Answers

Answer:

No direct answer but this might help out a little bit: <3

Explanation:

The mRNA is an RNA version of the gene that leaves the cell nucleus and moves to the cytoplasm where proteins are made. During protein synthesis, an organelle called a ribosome moves along the mRNA, reads its base sequence, and uses the genetic code to translate each three-base triplet, or codon, into its corresponding amino acid.

D It delivers DNA's instructions for making proteins to the ribosome

Sickle Cells:

These cells look like a crescent moon. They are unable to transport oxygen. This cause anemia in the patient.

It is an inherited disorder in which point mutation in the lead to the different protein structure. This results in the sickled RBCs.
