2. using antibiotics to treat infection

3. diagnosing genetic diseases

4. producing antibodies such as antitoxins

5. curing diseases such as smallpox

Answers

The correct answers are 1. Using stem cells to treat disease, and 3. Diagnosing genetic diseases.

Explanation

Biotechnology is a science that covers different areas such as chemistry, biology, and technology, to improve or facilitate procedures related to living organisms by manipulating living or parts of these in areas such as agriculture, medicine, and pharmacy. In the area of medicine, biotechnology is in charge of working with DNA to improve people's health. Also, it is in charge of investigating the cells to know in depth the problems that trigger diseases or genetic problems. Another use of biotechnology in medicine is through the use of stem cells in treatments for self-renewal or regeneration of damaged tissues. So, the correct answers are 1. Using stem cells to treat disease, and 3. Diagnosing genetic diseases.

Consumers differ from producers in that unlike producers, consumers .b. cannot make their own food.

Producers can make their own food and energy, but consumers are different. Living things that have to hunt, gather and eat their food are called consumers. Consumers have to eat to gain energy or they will die. There are four types of consumers:

omnivores, carnivores, herbivoresdecomposers.How do consumers differ from producers?

The producers generate food for themselves and others; consumers do not produce anything, instead eating producers, other consumers or both. Organisms that eat only producers (i.e., plants) are called herbivores. Animals that eat only consumers (i.e., meat) are called carnivores.

This Pedigree represents a family with an Autosomal Recessive Disorder. What is the probability that IV4 and IV5 have a child with the trait?

Answers

As this family has an Autosomal Recessive Disorder, we must know that this disorder will only be expressed, in the family members who are homozygous recessive (aa), in this way, to know the probability of IV-4 and IV-5 to present the disorder, we must evaluate the probabilities of combinations of their parents' alleles in a diagram called a punnett square.

In the pedigree above, we can see that the dark colored balls and squares represent the members of the family who have the disorder and therefore have the "aa" genotype.

Thus, when observing the crossings throughout the family, we know that the father of IV-4, has the genotype "Aa", however we do not know which genotype of the mother of IV-4, but as she does not have the disorder, she may have the genotype "Aa", or "AA", for that reason, we must make the punnett square for both situations and see what the probabilities of IV-4 will present the disorder.

As you can see in the figure attached below, if IV-4's mother has the "Aa" genotype, IV-4 will have a 25% chance of presenting the disorder. If IV-4's mother has the "AA" genotype, IV-4 has a 0% chance of inheriting the disorder.

In the case of IV-5, we can see that his mother has the disorder and therefore has the genotype "aa", we know that his father does not have the disorder, but we do not know if the father's genotype is "AA" or "Aa "and therefore we must evaluate both situations.

As you can see in the figure below called "IV-5", if IV-5's father has the "AA" genotype, IV-5 will have a 0% chance of inheriting the disorder. However, if IV-5's father has the "aa" genotype, IV-5 will have a 50% chance of inheriting the disorder.

Q1:
A male child with wavy hair is born to a mother with curly hair and a father with straight hair.

Which type of inheritance best explains the child’s hair type?

A
codominance because the child’s hair type is a blend of the parental hair types
B
codominance because both the male and the female carry the gene for hair type
C
incomplete dominance because the child’s hair type is a blend of the parental hair types
D
incomplete dominance because both the male and the female carry the gene for hair type

Answers

Odpowiedź:

A) codominance because the child’s hair type is a blend of the parental hair types.

Wyjaśnienie:

AA - curly hair

aa - straight hair

Aa - qualities AA + qualities aa = Wavy hair  

The type of inheritance that best explains the child’s hair type is codominance because the child’s hair type is a blend of the parental hair types. The correct option is A.

What is inheritance?

Inheritance is the transfer of genes and characteristics from the parent generation to the offspring. It is done in sexual reproduction. The traits of the mother and the father are transferred into the child.

Codominance is a type of inheritance in which the traits of the father and the mother get blended and a third different type of trait is shown in the offspring.

Here, the father has straight hair, and the mother has wavy hair, but the male child shows the hair is wavy hair. This shows the process of codominance in the child.

AA - curly hair

aa - straight hair

Aa - qualities AA + qualities aa = Wavy hair.

Thus, the correct option is A. codominance because the child’s hair type is a blend of the parental hair types.

Explanation:

According to the Darwin’s theory of survival, a species can survive among its peers only when it is fit enough to adapt to the natural changes and hence remain alive till its reproductive stage in order to produce fertile offspring.  

Such species which survive are known as fit species while the remaining unable to cope with changing environment die out at an early stage of life.

Some populations will migrate out of the deforested area.

Explanation:

The deforested land will be able to support large trees eventually in the future, and animals cannot instantly adapt to anything.

Therefore, the most logical answers are populations will migrate to forest lands and species will eventually develop adaptations to help them in the newly deforested land.

Which of the following is the best definition of the term genotype?

Answers

A genotype is a feature in the genes. I know this since a pheno is a physical trait while geno meaning gene is a trait in the genes that can't be seen.

The genotype refers to an organism's entire genetic makeup, including all of its inherited genes.

What is a genotype?

It represents the underlying genetic information that determines the traits and characteristics an organism will have, such as eye color, height, and susceptibility to certain diseases.

The genotype is influenced by the combination of genes passed down from parents and can also be affected by mutations or changes in the DNA sequence. The genotype serves as the blueprint for an organism's development and can impact its phenotype, or observable traits and characteristics.

A student plays football outside on a hot day and lost a significant amount of water in sweat. How will this affect his blood volume?
A.Blood volume decreases
B. Blood volume stays the same
C. Blood volume increases

Answers

Answer:

A.Blood volume decreases

Explanation:

Blood volume refers to the fluid substances including blood circulating in the body via blood vessels. The blood volume must be optimal in order to ensure that every organ in the body gets an ample amount of blood. One of the things that can result in alteration of the normal blood volume is DEHYDRATION, which is the loss of water from the body.

Dehydration decreases the blood volume because the water content in the blood becomes decreased as water is lost, which would have detrimental effects on the body because the blood pressure (force at which blood flows) will be reduced.

This is the case of the student in this question that loses a significant amount of water as sweat when he undergoes exercise in a hot weather condition. The loss of water will result in the decrement of his blood volume.

DQ19: A pea plant must have exactly one of each of the following pairs of traits: Short (s) or tall (t); round (r) or wrinkled (w) seeds; yellow (y) or green (g) peas; and white (wh) or purple (p) flowers. For example, a pea plant can be short with wrinkled seeds, green peas and white flowers. How many different classifications of pea plants are possible

Answers

Answer:

There are 16 possible different classifications of pea plants.

Explanation:

In order to get the number of classifications, you must multiply all the possibilities by each other in each trait. This is, each trait has two states (short or tall, round or wrinkled, yellow or green, white or purple) and are referred to as "pair of traits". These must be multiplied with the other pairs of traits. So, the number of different classifications of pea plants is:

the number of high states x number of shape states x number of peas color sates x number of flower color states = 2 x 2 x 2 x 2 = 16.
