3. The doctor tests the patient's field of view with an astigmatism chart and finds that the patient states that there are blind spots and distorted lines in both eyes he never noticed before. These blinds spots and distortions remain constant. What structure within the eye could cause these distortions? How can you verify your suspicion?

Answers

Answer 1

Astigmatism is also a eye condition which is usually evidenced by distorted visions and leading to the creation of an image that is not perfect.

The structure within the eye that would cause the distortions is caused by a deviation in the shape of the lens of the eye or the cornea.

A change that occurs in the shape of the cornea/lens where it is not completely round as it should be usually leads to seeing distorted lines in one's vision and it can occur maybe from birth, even from injury to the eyes.

One can always verify this suspicion by going to seen an optometrist and doing a comprehensive eye examination to verify the condition. The condition is also treatable.

A. yellow
B. brown
C. black
D. white

Answers

Answer:

The color of a dog's fur with the genes aabb would be yellow. So, in other words, Option A is correct.

Hope this helped :D Happy holidays! :D

Epistasis is the effect or character appear due to the interaction between genes. Here, the alleles responsible for the color of dog's fur show epistasis and the progeny with (aabb) genotype will show white colored fur. Thus, the correct option is D.

What is Epistasis?

Epistasis is also known as gene masking, where the expression of one gene is modified or masked or suppressed by the expression of another gene or more other genes. In this, more than one gene controls a specific character such as fur color, etc.

Epistasis is of different types such as dominant epistasis, recessive epistasis depending upon the effect of genes.

Here, the progenies with AABB genotype show black colored fur, the progeny with Aabb show brown colored fur, the progeny with genotype aaBB show yellow colored fur, and therefore, the progeny with genotype aabb i.e., both the recessive genes will show white colored dog fur.

Therefore, the correct option is D.

An man about 80 years old, lives alone. He looks very weak and undernourished. His lower limbs bones are tender and thin.

All bone formation is a replacement process. During development, tissues are replaced by bone during the ossification process. In intramembranous ossification, bone develops directly from sheets of mesenchymal connective tissue. In endochondral ossification, bone develops by replacing hyaline cartilage, bone formation, also called ossification, process by which new bone is produced. ... Soon after the osteoid is laid down, inorganic salts are deposited in it to form the hardened material recognized as mineralized bone. The cartilage cells die out and are replaced by osteoblasts clustered in ossification centres.

During the process of photosynthesis,
which of the following is being created
by producers?

Answers

Answer:

Producers are the plants that use sunlight, water, and carbon dioxide to make their own food. They are called producers because they produce sugars from CO2 which they share with the rest of the world through photosynthesis. The carbohydrates, fats, proteins etc in your diet were all originally made by green plants! All green plants need is CO2 and water to live.

Which is a heterotroph?
A. Grass
B. Lion
C. Dandelion
D. Oak Tree​

Answers

Answer:

Lion

Explanation:

Heterotrophs are known as consumers because they consume producers or other consumers. Dogs, birds, fish, and humans are all examples of heterotrophs. Heterotrophs occupy the second and third levels in a food chain, a sequence of organisms that provide energy and nutrients for other organisms.

Mountain lions, or cougars, are carnivorous heterotrophs and feed on a wide range of prey, such as insects, small mammals, reptiles and birds, but their most common prey is deer.

Grass, like the majority of green plants, is autotrophic. Thus, Grass produces its food through the photosynthesis process, which uses solar energy, water, and carbon dioxide. Thus, it is not a Heterotroph.

Dandelion is a typical photosynthetic autotroph. (Dandelion) An autotroph is an organism that can produce its own glucose and use it as energy. The Dandelion is a plant that can preform photosyntesis by collecting sunlight, water, and nutrients and create it’s own glucose. This makes the Dandelion an autotroph.

Trees, like all other plants, are autotrophic, meaning that they can produce food through the process of photosynthesis. Oak trees are considered autotrophs because they produce their own food.

In sexually reproducing organisms, meiosis is a unique type of cell division that results in the production of gametes, such as sperm or egg cells. It involves two division rounds that produce four cells with just one copy of each chromosome.

Gametes, or sex cells, are produced during meiosis. Each of the four haploid daughter cells produced during meiosis has half the number of chromosomes as the parent cell.

which of the following statements best describes nucleic acids?

Answers

Answer:

Large nitrogen-containing polymers found mainly in cell nuclei

Explanation:

The statement that best describes nucleic acids is that they are large nitrogen-containing polymers found mainly in cell nuclei, which is present in Option A. Nucleic acid includes both the DNA and the RNA, and in eukaryotes, these are found in the nucleus.

What is nucleic acid?

The nucleic acid consists of DNA and RNA, which are made up of nucleotides, each of which is composed of a sugar, either deoxyribose sugar (DNA) or ribose sugar (RNA), phosphate, and a nitrogen base. In humans and other eukaryotes, DNA and RNA are present in the nucleus. In the human cell, the DNA is double helical, with hydrogen bonds connecting the strands.

While RNA is a single chain, the majority of it does not form a double helix. Nucleic acids carry out the gene expression present in the cell.

Answers

Sociologists argue that the division of the human population into two distinctive and  mutually exclusive categories, male and female, is best understood as a biological fact.

The division into these two major categories as male or female is mainly due to the biological and the physiological characteristics produced in both male and female.

Although in some cases, it may be argued that they are not mutually exclusive as there are some who have both.

Nevertheless, the above mentioned characteristics are just used to differentiate between a male and a female in humans and as well an individual self-concept of being a male or a female.

Answers

Answer:

Cell is the basic unit of life and they contain the needed information known as the DNA (genetic material) to carry out the basic life functions and processes.

All cells in the body essentially have the same genome except some red blood cells and some immune cells.

Red blood cells do not contain as DNA as they lack a nucleus so they are an exception to the rule. While some immune cells needs to reassemble their genome in order to aid in the production of antibodies.

Actually, gene expression comes in with this because cells become different as a result of the fact that a cell can decide which gene is to be expressed or not in accordance to its function it is supposed to perform.
