Answer:

Males and females have different sex chromosomes.

Explanation:

Sex Linked trait is controlled by the chromosomes while other traits are controlled by autosomes. The autosomal cells and traits have a constant characteristics in a human being. The chromosomal cells however vary. The male chromosome XY is different from the female chromosome XX.

This is the reason why sex-linked traits follow different patterns of inheratance than other traits as a result of the Males and females having different sex chromosomes is valid.

Answer:

One example of a harmful mutation is an animal's different coloring than others in its species. If a deer was albino, it would have a much harder time blending in, escaping predators and most likely have trouble finding a mate.

Explanation:

Answer:

1. separation can be done with help of magnetic bar and filtration.

2. the next step will be testing the hypothesis.

Explanation:

1. Separation of iron pellets from sand,  and salt first

Use a magnet

Due to magnetic force iron pallets will attach with it and separation will occur from sand and salt.

After separation of iron pallets, add water to mixture of sand and salt and heat until salt get dissolved then filter the salt water.

This will help in separating all three components of mixture to separate.

2. Bacteria growth

Hypothesis must be tested-

In this case a hypothesis and conclusion is represented. Conclusion is provided that in presence of sunlight growth of bacteria is faster. So the hypothesis must be verified by scientific experiment to be a valid theory by measuring or monitoring growth in presence of sunlight.

Answer:

The correct answer is option d. "includes a large sample size and a control, and alters only one condition between the controls and the experimental condition".

Explanation:

The correct answer for this question is missing, which is option d. "includes a large sample size and a control, and alters only one condition between the controls and the experimental condition". The best experimental design includes all the options proposed: it includes a large sample size to ensure that the data is statistically relevant; a control to verify that the results are valid and are not obtained from other untested conditions; and it alters only one condition at the time to ensure the existence of the relation between condition and results.

Answer:

The slime molds are important to ecosystems because they act as decomposers which will release nutrients back into the environment. Earth basically depends on protists because they supply oxygen and are critical in the food chain.

Answer:

Lysine

Explanation:

Lysine is a unabbreviated name of amino acid. It is used in biosynthesis of proteins. It contains [tex]\alpha[/tex]-amino group and [tex]\alpha[/tex]-carboxylic acid group which has formula is C6H14N2O2. Lysine is also considered as building block of amino acid. It is used for treating cold sores and can be applied directly to the skin.

Answer:

Ribonucleic acid (RNA)

Explanation:

DNA (deoxyribonucleic corrosive) is the most widely recognized type of hereditary material found in numerous living beings.

Nucleic acids connect the two strands of the DNA double helix together.

RNA (ribonucleic corrosive) is additionally found as genetic material (and not DNA) in certain creatures like infections.

Infections could have ssRNA (single-stranded RNA) or dsRNA (double-stranded RNA) as their hereditary material.

However, RNA is generally single-stranded, in contrast to DNA, which is double-stranded consistently.

Another type of RNA is messenger RNA (mRNA), ribosomal RNA (rRNA), transfer RNA (tRNA), etc

Answer:

Evolution is the process of genetic change from one generation to the next and may be caused by several methods. In essence, evolution occurs when some individuals or some alleles (gene types) reproduce themselves more than others,increasing their prevalence in subsequent generations.

Answer:

Acid

At the simplest definition, an acid is any compound that yields hydrogen ions (H +) or hydronium ions (H 3O +) when dissolved in water. Hydronium ions are really the combination of H + ions and H 2O molecules

Explanation:

Answer:

The correct answer is "strengths: inexpensive, easy to culture, short life cycle, large number of offspring; weaknesses: invertebrate model, some diseases such as immunological cannot be modelled, anatomical features are very different from humans"

Explanation:

The fruit fly Drosophila melanogaster is one of the most used animal model for genetic and biomedical studies. There are many advantages of using Drosophila as model, including that it is very inexpensive to handle, it is easy to culture, it has a short life cycle allowing to observe the changes in phenotype very quickly and its large number of offspring allows to include several repetitions per trait in a study. However, there are some weaknesses of using Drosophila to study human biology. First, obviously the fruit fly is very different from humans, it is an invertebrate and its anatomical features are very different, which makes impossible to model some disorders such as immunological diseases.

Answer:

Prokaryotic cells are less structured than eukaryotic cells. They have no nucleus; instead their genetic material is free-floating within the cell. They also lack the many membrane-bound organelles found in eukaryotic cells. Thus, prokaryotes have no mitochondria. I hope this helped.

1. oxygen

2. nose and roots

Answer:

The skeletal muscle is stimulated by means of action potentials that are caused by the neuromotor plate. These action potentials are one after the other and can become cumulative once the muscle fibers pass the refractory phase of the action potential.

The refractory stage is that stage in which action potentials are not admitted, therefore where the muscle fibers do not accept stimuli to contract.

Once this refractory stage is over, more action potentials can be admitted, which would be summative and the muscle fiber would contract with greater power.

Explanation:

If a muscle is repeatedly stimulated, the contraction will be weaker or the muscle will fatigue more easily, triggering muscle failure.

If the muscle is stimulated with a longer pause between contraction and contraction, the action will be performed with more power.

Answer:

Explanation:

The next step in this experiment is constructing a hypothesis and recording data. The correct option is (C).

Making observations and keeping track of data would be the experiment's next phase. The learner would observe and record the ripening of both apples at locations A and B in this stage. They would have to keep track of the maturity of the apples throughout time by routinely observing and recording the changes. This could entail examining the apples visually for color, texture, and overall maturity and recording any variations between the apples at locations A (by themselves) and B (next to a banana).

The student can analyze the results and develop conclusions regarding the impact of bananas on the maturity of other fruits by gathering information on the ripening of the apples in both locations. The information can be used to prove or disprove the initial theory and assist determine whether bananas actually influence the maturity of surrounding fruits.

Hence, the correct option is (C). Construct a hypothesis and record data.

Explanation:

Answer:

a. True

Explanation:

When the stream dried up darker coat mice were seen into the lighter coat population and vice versa because of the natural selection process.

Mice change their coat color by adapting the changes in the stream flow and evolve their coat either dark or light that provides camouflage so predators won’t see them and they are able to survive in the environment. Mice have the advantage of surviving long and they are able to pass their genes to the offspring.

Hence, the given statement is true.

Answer:demand for resources such as fossil fuels

Explanation:

Building large manufacturing facilities can affect ecosystems by increasing the demand for resources such as fossil fuels.

Thus, The breakdown of buried, carbon-based organisms that perished millions of years ago produces fossil fuels. They produce deposits rich in carbon, which are taken out and burned to provide energy.

They presently provide about 80% of the world's energy and are non-renewable. A vast array of items, including plastic and steel, are also produced using them. Coal, oil, and gas are the three forms of fossil fuels.

Global warming is mostly caused by emissions from fossil fuels, according to the Intergovernmental Panel on Climate Change (IPCC). 89% of the world's CO2 emissions in 2018 came from industry and fossil fuels.

Thus, Building large manufacturing facilities can affect ecosystems by increasing the demand for resources such as fossil fuels.
