Which best describes a recessive allele?

A. Always inherited from a parent when a dominant allele is inherited from the other parent.
B. Never inherited from a parent when a dominant allele is inherited from the other parent.
C. Only determines phenotype when a dominant allele for the same trait is present.
D. Does not determine phenotype when a dominant allele for the same trait is present.

Explanation:

The difference between science and pseudoscience is that science relies on experimentation and data gathered.

Pseudoscience is based solely on one's opinion rather than fact. in the early 1800's, scientists used to speculate what type of a person you are or intelligence by the shape of your head.

Answer:

As the water table goes low, water may not be easily obtained leading to it scarcity. Overdrawal of water can also lead to sinking or lowering of the land surface that can make it prone to flooding. Streams and water bodies may also get disconnected due to over-withdrawal of water.

Answer:

According to the Law of segregation presented by Mendel, each gamete receives just one copy of every allele randomly. Normally all the cells follow the Mendelian inheritance.

In Down's syndrome, an individual gets 3 copies of a chromosome instead of the normal chromosome pair. This is also known as trisomy 21. It does not follow the law of segregation of Mendelian inheritance as it gets three instead of two.

Answer:

6. Parasitism

9. mutualism

10. predation

7. predation

8. mutualism

Explanation:

Living organisms, in their natural habitat, forms certain relationships with one another. These relationships are as follows:

- Mutualism is the association of two organisms in which both organisms benefits from one another in the relationship. Example is butterfly and flower in this question, where the butterfly helps pollinate the flower while the plants provide food source for the butterfly. Another example is coral reefs and fishes where the fishes and coral depend on one another.

- Predation is the kind of relationship in which one living organism called PREDATOR kills and feeds on another called PREY. Examples are the relationship between birds and worms, lion and buffalo where the bird and lion are predators while worm and buffalo are preys.

- Parasitism is the relationship between two organisms in which one organism called PARASITE lives on and derive nourishments from another organism called HOST. In the example of aphid and rose plant where the aphid is the parasite and rose plant is the host.

The type of interaction that is being performed by the following pairs of

organisms include the following:

Aphid and rose plant have a parasitic relationship due to the aphids taking

up vital nutrients from the rose plant thereby resulting in distorted growth.

Butterflies and flowers have a mutualistic relationship as the butterfly aids

pollination of the flowers and also derives food and juice in return.

Birds and worms have a predatory relationship as the birds eat worms for

food and survival.

Lion and buffalo  have a predatory relationship as the Lions eat buffalos for

food and survival.

Coral reefs and fishes have a mutualistic relationship as the fishes aids

reproductive ability of the coral reefs while the fishes benefit food and habitat in return.

when CuSO4dissolved in water, no chemical reaction takes place since no new substance is getting formed.Thus it is a physical change. The dissolution of Zinc granules in dil. HCl is a chemical change because zinc reacts with hydrochloric acid to form zinc chloride and hydrogen gas is liberated.

I think yes, because from what i knew. When the DNA replicate, it will be same as the original/mother DNA. so it will both have radioactive DNA.

Just think, if only one DNA have radioactive then it wont be dangerous, but it affect the replication DNA, then its different case and will be dangerous for the body. You must've heard that radioactive can be dangerous for the body.

Sorry if im wrong

c. Liver breaks down glycogen and releases glucose to the blood.

Explanation:

Living system can be defined as the internal systems found in living organisms and how various materials are circulated inside organisms.

Generally, these living systems are self-organized life forms and are known to be very much interactive with their surroundings or environment. Also, living systems are dependent on the flow of information, matter and energy at various levels.

Some examples of living systems in organisms are respiratory system, nervous system, digestive system, and circulatory system.

Additionally, living systems comprises of the following components; cells, organs, muscle, tissues, blood, etc.

Organs can be defined as specialized body tissues united to perform specific functions in living organisms. Some examples of organs found in humans are brain, bladder, kidney, heart, intestine, eyes, lungs, liver, etc.

A liver refers to a large, essential organ that is reddish-brown in color which is used to synthesize proteins, secrete bile, and the detoxification of metabolites.

Glycogenolysis can be defined as a process which typically involves the breaking down of the primary carbohydrates (glycogen) present in liver into glucose so as to maintain blood glucose rates and provide necessary energy for living organisms.

Hence, the true statement is that liver breaks down glycogen and releases glucose to the blood.

In the US, 1 in 1700 Caucasian children will be born with the monogenic hereditary disorder Cystic Fibrosis (CF), a pathology that results in an accumulation of abnormally sticky and thick mucus affecting the lungs and digestive system. Consider a small isolated community in Appalachia where most of the population lives below the poverty level and where adults have a higher rate of CF that the national average since the people tend to marry neighbors. The general practitioner for the county receives a Bill and Melinda Gates Foundation Grant to ascertain how many children in the community inherited cystic fibrosis from their parents. Out of 172 children tested, she finds 38 have CF. Remember that Mendel believed in diagnostic ratios for understanding inheritance outcome although other factors can come into play like assortative mating.

Based on the testing outcome, give your opinion on whether you think Cystic Fibrosis is a dominant or recessive disorder.

A.Probably dominant.

B.Probably recessive.

C. Neither

D. Not enough information
