The right ventricle's function is to pump blood into the lungs so that it can be oxygenated. The correct option is C.
Thus, deoxygenated blood from the right atrium is taken up by the right ventricle and pumped into the pulmonary artery, which transports the blood to the lungs. Through the act of breathing, the blood obtains oxygen in the lungs and releases carbon dioxide.
The oxygenated blood is then returned to the left atrium of the heart where the left ventricle pumps it to the remainder of the body. As a result, the right ventricle's main job is to pump blood to the lungs where it may be oxygenated.
Thus, the ideal selection is option C.

Chromosomes are inherited from the parents. One chromosome from each of 23 pairs came from each of the parents. The two chromosomes of a pair (except for the sex chromosomes) contain the same genes, but the genes have small differences. The X and Y Chromosomes determine the organism’s sex. One chromosome pair - the sex chromosomes - is unique. Typically females have two X chromosomes and males have an X and a Y. Mothers always pass an X chromosome on to their children. Whether the father passes on his X chromosome (leading to a pair of X chromosomes) or his Y chromosome (making a mixed set) determines your sex. Chromosomes get shuffled when eggs and sperm are made. Though most adult cells contain two sets of chromosomes, sperm and egg cells are different. These special cells have just one chromosome from each pair. Which chromosome they get from each pair is random, making each sperm or egg cell unique. There is also a bit of mixing before the chromosomes are sorted into individual sperm or egg cells. Chromosomes from each pair in a mother or father, respectively, make contact and exchange pieces of DNA, creating hybrid chromosomes.
Answer:
Explanation:
genes and DNA code for the production of proteins, which can cause traits to be expressed .
B. the parent animal divides into two new animals
C. the offspring develops as an outgrowth of the parents body wall.
D.an egg develops without being fertilized by a sperm
Parthenogenesis is a method of reproduction in which an egg develops without being fertilized by a sperm. The correct option is D.
An unfertilizedegg produces a child without the help of male gametes (sperm) in this type of asexualreproduction.
Since they only receive geneticmaterial from the female parent, parthenogenesis produces kids that are often genetically identical to or very similar to the parents.
Numerous creatures, including certain invertebrates, reptiles, and even some fish and birds, exhibit this mode of reproduction.
Without mating or geneticrecombination, offsprings can be produced due to parthenogenesis.
Thus, the correct option is D.

Answer:
The model clearly shows how digestion occurs in the cell and the organelles involved in the process. However, the model doesn’t show the other organelles in the cell or the environment in which the cell lives.
Explanation:
answer on edmentum.
Answer:
This is a model of a mitochondria. .
Mitochondria -: It is the powe house of the cell it contain oxidative enzymes that needed by the stepwise oxidation of food by CO2 and water . The energy released in this process convert to ATP and later it send to the other parts of the body for doing energy requiring activities.

Answer:
The question lacks options, the options are:
A) They are easier to transport and store than injectable vaccines (shots).
B) They make it easier to administer edible vaccines.
C) They are more expensive than potatoes without the vaccine.
D) They have nutritional value while potatoes without the vaccine do not.
Thw answer is C
Explanation:
Agricultural crops have faced series of problems caused by pest, nutrient composition etc. However, technology has made sure they these problems are reduced in the least possible way via the use of genetic engineering. Genetic engineering, also called genetic modification is the manipulation of an organism's genes using biotechnology procedures.
In this case, the potato crop was genetically modified, meaning that, the crop was improved genetically. Although, this process has many advantages like inserting a vaccine in the edible crop and easy storage, it also has disadvantages. One of these disadvantages as mentioned in the options is that they become more expensive than potatoes without the vaccine. The price increases due to the vaccines they now contain in comparison to the potatoes without vaccine (not genetically modified).
This price can become not affordable for an average person. Hence, it is a disadvantage of the genetically modified potato crop
