A dominant allele is often covered up or masked by the recessive allele. True or false?

Answers

Answer 1

Answer:

Explanation:In a heterozygote, the allele which masks the other is referred to as dominant, while the allele that is masked is referred to as recessive.

Answer 2

Answer:

If the alleles are different, the dominant allele will be expressed, while the effect of the other allele, called recessive, is masked. In the case of a recessive genetic disorder, an individual must inherit two copies of the mutated allele in order for the disease to be present

Bart thinks mice exposed to microwaves will get stronger (maybe he's been reading too much Radioactive Man). You decide to perform this experiment by placing 10 mice in a microwave for 10 seconds. He compared these 10 mice to 10 other mice that had not been exposed. His test consisted of a heavy block of wood that blocked the mouse's food. found that 8 out of 10 of the microwave mice were able to push the block. 7 out of 10 of the mice without microwaves were able to do the same.

identify
1. control group
2. independent variable
3. dependent variable
4. what are some of the mentioned control variables?
5. what should bart's conclusion be?​

Answers

Answer:

Control group = mice that had not been exposed

Independent variable = Mice receiving radiation

Dependent variable = Number of mice that are able to push the block of wood.

Control variables = Health of mice, mass of block

Radiation does not have effect on strength of the mice

Explanation:

In an experiment the variable which changes with respect to the other variable is called the dependent variable and the other variable is called the independent variable.

The control group is the group that does not receive treatment which is used to compare the effect of the treatment.

The control variable is another variable that must be held constant when performing the experiment.

Here the

Control group = mice that had not been exposed

Independent variable = Mice receiving radiation

Dependent variable = Number of mice that are able to push the block of wood.

Control variables = Health of mice, mass of block

It was found that 8 out of 10 of the microwave mice were able to push the block. 7 out of 10 of the mice without microwaves were able to do the same. This means that there was no significant difference hence, the conclusion drawn should be that radiation does not have any effect on their strength.

If transpiration didn't take place, would water be able to enter the roots of the plant? Explain your reasoning

Answers

Answer:

Yes

Explanation:

If transpiration do not occur water will enter the roots of the plants because water enter through the roots by osmosis and move to the xylem vessels after which it get to the leaves and it is lost by evaporation and transpiration. Transpiration is the process why by water is loss through the stomata opening of the leaves and this help in exchange of gases, reduction of excess water and help in plant growth.

Explain how the structures of plant tissues and organs are directly related to their roles in physiological processes.

Answers

Answer:

How the structures of plant tissues and organs are directly related to their roles in physiological processes.

o Plant organs are limited to roots, stems, leaves, flowers, fruit and cones.

o Physiological processes are limited to photosynthesis, cellular respiration,

transpiration, and reproduction.

o Plant tissues are limited to meristematic, ground, dermal and vascular tissues.

o Plant structures are limited to cambium, guard cells, phloem, seed, stomata and

xylem

Explanation: Hope this helps have a safe and happy new year

Roots, stalks, leaves, flowers, fruit, and cones are the only organs found in plants. Photosynthesis, metabolic processes, transpiration, and fertilization are the only physiological activities.

Plant and plant tissues:

Photosynthesis and the movement of mineral-containing water ions are critical processes in the development of healthy plants. Plants have three primary structures or organs:

LeavesStemsRoots

They're made up of groupings of specialized tissues with structures that are tailored to the functions they do.

Adaptations are distinctive features that help plants survive in their specific settings. Plants rely on their specialized structures to provide their fundamental requirements, protect themselves from predators, and aid reproduction.

freely movable joint is also known as synovial joint why​

Answers

Answer:

Why are synovial joints freely movable?

Diarthroses are freely movable articulations. ... The bones of a synovial joint are covered by a layer of hyaline cartilage that lines the epiphyses of joint ends of bone with a smooth, slippery surface that does not bind them together. This articular cartilage functions to absorb shock and reduce friction during movement.

Explanation:

please give me brainly got my answer from G00GLE so of course its correct hope i helped!!!

Answer:

Explanation:

Synovial joints (freely movable joints) allow us the free movement to perform skills and techniques during physical activity. Synovial joints have synovial fluid in the joint cavity that lubricates or 'oils' the joint so it moves smoothly. Synovial fluid is made by the synovial membrane.

A girl is born with hemophilia. Her dad also has hemophilia, but her mother does not.

What genetic explanation can you provide as to why the girl
suffers from hemophilia?

Answers

answer:

So daughters get 2 X chromosomes from the mom and dad and if the dad has hemophilia the daughter would get it too and sons would not get because they get Y chromosome from their dad and hemophilia is found in the X chromosome because the X chromosome is the one that has the instructions for making the clotting factor proteins.

Explanation:

A father who has hemophilia has the gene and passes it on to his daughter because daughters get two X chromosomes, one from their mother and the other from their father. This is why daughters of men with hemophilia are called obligate carriers. Since sons only receive a Y chromosome from their father, they would not have inherited hemophilia.

Explain the relationship between a drainage basin and a divide. 10 POINTS HELP PLS!!on a raw, soggy day in March 1936, Dorothea Lange was driving home to Berkeley after six weeks spent photographing migrant workers in California, New Mexico and Arizona. Her staff position at the Resettlement Administration (RA), an agency set up to help tenant farmers during the Depression, was tenuous: since there was no budget for a photographer, Lange had been hired as a clerk-stenographer, and she invoiced her film and travel expenses under "clerical supplies."As Lange drove along the empty California highway that day, she noticed a sign that said Pea-Pickers Camp. Knowing that the pea crop had frozen, she debated for 20 miles before finally turning back. After pulling into the camp's muddy lane, Lange approached a female migrant worker, requested and got permission to photograph her and shot just five exposures. Lange's field notes read in part: "I did not ask her name or her history. She told me her age, that she was 32. She said that they had been living on frozen vegetables from the surrounding fields and birds that the children killed. She had just sold the tires from her car to buy food."Back home, Lange developed the images and, clutching the still-wet prints, told the editor of the San Francisco News that migrant workers were slowly starving to death in Nipomo, California.Migrant Madonna,Rebecca Maksel,2002What is the historical context of these sources?
