The primary reason that osteoporosis accelerates after menopause in women is: * 2 points A. Increased osteoblast activity. B. Reduced levels of vitamin C. C. Diminished osteoclast activity. D. Reduced levels of circulating estrogens.

Answers

Answer 1

Answer:

The correct answer is D. Reduced levels of circulating estrogens.

Explanation:

Estrogens prevent the loss of calcium and ensure its proper mineralization, thus preventing the bones from becoming brittle, maintaining the consistency of the skeleton and preventing osteoporosis. Osteoporosis is a skeletal disease in which there is a decrease in bone mass density. Thus, the bones become more porous, the number and size of the cavities or cells that exist inside them increases, they are more fragile, they resist shocks worse and they break more easily. Menopause is the definitive cessation of ovarian function that, externally, results in the disappearance of the menses and usually occurs around 50 years (the interval goes from 45 to 55 years). It is the gradual loss of calcium in the bones, which accelerates in the first years of menopause due to estrogen deficiency. At the beginning of the disease, there are no symptoms and, as it progresses, there is a tendency to suffer fractures, which leads to a decrease in height.

Artificial selection has produced a wide variety of crop plants, livestock, and pets. Which characteristic of artificial selection makes it different from natural selection

Answers

Answer:

Genetic Problems

Explanation:

When people genetically modify animals, they can mess up a lot of their natural abilities. For example in some cases scientist have made cows who produce more milk, but couldn't reproduce anymore because of it. Sometimes it even hurts the animal. People have bred dogs in certain ways that makes it hard for them to breathe, like Bull dogs who has respiratory issues. This makes decreases their life span and continuing to bred them will only make it worse. When scientist have a certain trait they want they also make animals breed with their own families. Incest creates a lot of genetic problems.

If more individuals are born with the advantageous trait in each generation, over time what do you predict will happen to the percentage (%) of the alleles (gene variety) that code for this trait in the population?

Answers

Answer:

The percentage (%) of the alleles that code for this trait in the population will increase, as more individuals are born with the trait.

Explanation:

The more individuals get born expressing the trait, the higher its frequency gets in the population. By generation, there are more individuals carrying the allele for the advantageous trait. These individuals reproduce and increase the probabilities of the progeny to inherit the mentioned allele. When this sequence keeps occurring in the population over many generations, the allele percentage will increase. On the other hand, the other allele or alleles will decrease. Probably, if there are no changes that might influence or affect this pattern, the alleles for the advantageous trait will fixate, while the other allele might get lost.

How does a plant cell differ from an animal cell? Group of answer choices A plant cell can make its own glucose; an animal cell cannot A plant cell cannot synthesize proteins an animal cell can. A plat cell cannot perform cellular respiration; an animal cell can.

Answers

Answer:

plant cell can make its own glucose; an animal cell cannot

Explanation:

Chloroplasts are found in plant cells, but not in animal cells. The purpose of the chloroplast is to make glucose that feed the cell's machinery. Photosynthesis is the process of a plant taking energy from the Sun and creating glucose.

Photosynthesis uses energy from the Sun to make sugars such as glucose. What has to happen to the glucose before it can be used by plant cells?


A The glucose combines with another sugar to make usable energy.
B The glucose combines with oxygen to make usable energy.
OC The glucose combines with carbon dioxide to make usable energy.
OD Nothing has to happen to the glucose. Plant cells can use it as is.

Answers

Answer:

Respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy. This energy is used to fuel growth and all of the normal cellular functions.

D Nothing has to happen to the glucose. Plant cells can use it as is.

What happens to the glucose produced by plants?

Glucose produced by photosynthesis is a simple sugar that is used by plant cells as a source of energy and as a building block for other organic compounds. The glucose can be transported within the plant and used directly by cells as a source of energy through cellular respiration.

In cellular respiration, glucose is combined with oxygen to release energy in the form of ATP (adenosine triphosphate), which is used to fuel various cellular processes. So, there is no need for glucose to undergo any additional chemical reactions before it can be used by plant cells.

The opossum, which is native to North America, and the kangaroo, which is native to Australia, are marsupials.
The fact that both these mammals incubate their immature offspring in a pouch provides evidence that they -
O are descended from a common ancestor
O belong to the same species
O must range great distances to eat
have very similar skeletal structures

Answers

Answer:

Belong to the same species

Explanation:

Marsupials carry their young in "pouches", and are therefore related to other marsupials, like the kangaroo, opossum, wombats, and koala to name a few.

The opossum is a native of North America as the kangaroo is a native to Australia and both of them are mammals thus boh belong to the same specie. Thus option B is correct.

The components that make up the genetic code are common to all organisms. If a segment of a gene contains 27 nucleotides, none of which are stop or starts codons, how many amino acids does this segment code for?

Answers

Answer:

9 amino acids

Explanation:

A segment of a gene that has 27 nucleotides will code for 9 amino acids.

Each codon on the gene potentially represents an amino acid and a codon is made up of 3 nucleotides each. Hence, in order to find out the total number of amino acids that a gene segment with 27 nucleotides can code for, the number of nucleotides should be divided by 3.

    number of amino acids = number of nucleotides/3

                     27/3 = 9 codons/amino acids

Which level of organization is represented by the skeleton of the snake?

А.organ

B.organism

C.tissue system

D.organ system

Answers

The answer for this question is C

Tissue system, enables the snake to move forward by pushing against the ground while bending and curling its body. Thus, option C is correct.

What level of organization are present in snake?

The body of a snake is long and slender, and it is separated into four quadrants. Head, esophagus, heart, and trachea make up the first quadrant's major structures.

The second quadrant contains the liver, stomach, and anterior, vascularized region of the lung(s).

A snake has a basic skeleton because it has no arms or legs. Hundreds of ribs extend from the base of the tail to the end of the long, flexible spine that connects the head to the backbone.

This enables the snake to move forward by pushing against the ground while bending and curling its body.

Therefore, tissue system  level of organization is represented by the skeleton of the snake.
