The highlighted vessels are ________ blood to the heart. The highlighted vessels are ________ blood to the heart. arteries that carry deoxygenated veins that carry oxygenated arteries that carry oxygenated veins that carry deoxygenated
Answers
In the circulatory system, arteries take blood from the heart, and veins carry it to the heart. B) The highlighted vessels are veins that carry oxygenated blood to the heart.
What is the circulatory system?The circulatory system is a mechanism that, together with the respiratory system, provides oxygen to the organism and removes carbon dioxide.
The circulatory system is in charge of driving oxygen to all the tissues and cells in the body and taking away carbon dioxide from them.
These gases are in the oxygenated and deoxygenated blood, respectively.
The heart bombs blood through arteries
The oxygenated blood moves forward all tissues and cellsDeoxygenated blood goes to the lungs ⇒ pulmonary artery
This organ also receives blood through veins,
Oxygenated blood enters from the lungs ⇒ pulmonary veinDeoxygenated blood comes from other tissues
So the heart sends blood through arteries and receives blood through veins. Depending on the destiny and origin of this blood, it is oxygenated or deoxygenated.
There are two principal types of circulation,
Lung circulation
1. Moves blood between the heart and the lungs.
2. Deoxygenated blood goes from the heart to the lungs (pulmonary artery)
3. In the lungs, deoxygenated blood releases carbon dioxide and gets oxygenated again.
4. Carbon dioxide is released by exhalation.
5. Blood absorbs oxygen from small air sacs named alveoli.
6. Oxygenated blood returns to the heart (pulmonary vein).
Systemic circulation
1. Carries blood between the heart and the rest of the body.
2. Oxygenated blood leaves the heart and moves to all the cells in the body (arteries).
3. Deoxygenated blood returns from tissues to the heart (veins).
From the image,
The highlighted vessels are closely related to the lungs. So, according to their position and diametre, we can assume these are either pulmonary veins or arteries.If we consider the statement says that the highlighted vessels move blood TO the heart, we can assume we are talking about veins.
The only veins that move from the lungs to the heart carry oxygenated blood.
According to this reasoning, option B is correct.
The highlighted vessels are veins that carry oxygenated blood to the heart.

How would spraying a yard with chemical pesticides to control insects be most likely to affect the diversity of insects found in it? there would be fewer species of insects and fewer insects in general in the yard. there would be more harmful insects and fewer beneficial insects in the yard. there would be fewer harmful insects and more beneficial insects in the yard. there would be more species of insects, but fewer insects in general in the yard.
Answers
There would be fewer species of insects and fewer insects in general in the yard.
What are the effects of pesticides on insects?Lower pesticides doses or concentrations in field crops typically appear after the initial treatment because they decay due to a number of abiotic factors such rainfall, temperature, and sunlight. Insects may be exposed to insecticides in this fashion, at sublethal dosages or concentrations, in the wild, and may suffer effects that are sublethal.
Sublethal effects are those on people or communities that persist after exposure to a toxin at a lethal or sublethal dose or concentration. They might be biological, physiological, demographic, or behavioral.

Answers
The heterozygous probabilities will be 1/2; 1/4; 1/4
We can infer that since this is a rare characteristic, individual 1's mother is heterozygous and her father is homozygous for the wild type allele. The mother passed on an X to Individual 1, giving him or her a 50% chance of inheriting a mutant allele. Individual 3 has a 50% probability of inheriting the affected X chromosome from her mother if 1 is heterozygous, and a 100% chance of inheriting an affected X from her father.

Why is it important to maintain the ph of blood and tissue fluids within normal limits?
Answers
It is important to maintain the ph of blood and tissue fluids within normal limits because the structure and function of macromolecules are pH sensitive, and even little variations from normal pH can cause metabolic processes to shut down.
Tissue fluid is found in the spaces around cells. It comes from substances that leak out of blood capillaries (the smallest type of blood vessel). It helps bring oxygen and nutrients to cells and to remove waste products from them.
The two forms of connective tissue in this subcategory are blood and lymph. Both are fluid rather than solid, and neither has the network of extracellular protein fibers that other types of connective tissue have.
Diffusion and filtration processes create tissue fluid from plasma. This fluid fills the intracellular space and serves as a link in the transmission of nourishment, gases, and metabolic end products between blood capillaries, tissue fluid, and lymph.

A silver coin rubs vigorously against a wool cloth. the cloth becomes positively charged. which statements are true?
Answers
The silver coin gained electrons.

How does the transfer of electrons take place?
It is a given that woolen material becomes positively charged when a silver coin is rubbed against it. Since electrons are negatively charged particles, when a piece of clothing becomes positively charged, it has lost electrons.
However, because static electricity is created during rubbing, and if one substance becomes positively charged, the other will become negatively charged, a silver coin will absorb this negatively charged electron from the wool fabric and thus become negatively charged.
As a result, both choices B and C are accurate.

Biomolecules are made from simple monomers, yet you find a very high level of diversity. what chemical features make diversity in each category of biomolecules possible? provide examples in each case
Answers
Chemical features like 3-D structure and chemical bonding are responsible for diversity in biomolecules although they are made from simple monomers.
For example, in the case of carbohydrates, both starch and glycogen are made up of glucose monomers but still they differ in function in their body. This difference is because of the chemical bonding and the 3-D structure.
Similarly in protein biomolecules, amino acids act as the monomers but they differ in function due to their 3-D structure. Nucleotides are the building blocks of both RNA and DNA. RNA and DNA perform different functions in the body. DNA stores ad transfers genetic information while RNA is responsible for directly coding for amino acids.

Answers
The proportion of the population will be heterozygous carriers of the recessive allele is 0.48.
What is Hardy-Weinberg principle?
Hardy-Weinberg principle says that the allele frequencies in a population are stable and is constant from generation to generation. The gene pool (total genes and their alleles in a population) remains a constant. This is called genetic equilibrium. Sum total of all the allelic frequencies is 1.Individual frequencies, for example, can be named p, q, etc. In a diploid, p and q represent the frequency of allele A and allele a.The frequency of AA individuals in a population is simply p². This is simply stated in other ways, i.e., the probability that an allele A with a frequency of p appear on both the chromosomes of a diploid individual is simply the product of the probabilities, i.e., p².Similarly. that of aa is q² and of Aa 2pq.Hence, p²+2pq+q²=1, is a binomial expansion of (p+q)².By given data;
[tex]q2=16[/tex]
