Explanation:

Shortly after a stream dried up, you noticed a change in the field mouse population coat color variation. When the stream was flowing, there were two populations, one with darker coats and one with lighter coats. After the stream dried up, mice with darker coats were being born into the lighter coat population and vice versa.

a. True
b. False

Answers

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.

A receptor is a structure that detects stimuli. The stigma (eyespot) of Euglenoids detects ____, assisting with phototaxis. A. light intensity and direction B. vibrations C. chemicals D. sound frequency and direction E. temperature change

Answers

Answer:

The correct answer is option A, that is, light intensity and direction.

Explanation:

A photoreceptive organelle witnessed in the motile or flagellated cells of unicellular photosynthetic species like euglenoids and green algae is known as the stigma or the eyespot apparatus. It permits the cells of the organism to detect the intensity and direction of the light and react towards it.  

This assists the organisms to either swim away from the light known as negative phototaxis, or to swim towards it known as positive phototaxis. The eyespots are the basic and the most typical eyes witnessed in nature. The eyespots comprise bright areas or orange and red granules of pigment and photoreceptors.

The diffusion spot diameter with one crystal at 15 min ( mm) is 59 . The rate of diffusion with one crystal So how would I convert this 59 to ( mm/h)?

Answers

Answer:

This is straight forward.If  there are 60 minutes in one hour, then to convert minutes to hours as requested, simply divide the number of minutes given by  60.Thus if you divided the 59 by 60 it gives you what?round the answer to whole number.

When there is a moment of any solute present in the solution from high concentration to low concentration area is called diffusion.

It will take 0.25 hours to diffuse one crystal.

This can be calculated by:

Given,

Time for one crystal diffusion = 15 min

Diameter for one crystal diffusion  = 59 mm

In 1 hour there are 60 minutes.

60 minutes = 1 hour.

Then 15 minutes = ? hours

[tex]\dfrac{15 \; \text{minutes}}{60 \; \text{minutes}} = 0.25[/tex]

Therefore, to diffuse one crystal of it will take 0.25 hours.

Answers

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.

Explanation:

both ethanol and glycine are small molecules of approximately equal molecular weight. However, ethanol is much more membrane permeable than glycine. What accounts for the large difference in membrane permeability between ethanol and glycine

Answers

Answer:

Ethanol is a non polar molecule.Therefore it passes through the cells membrane easily by diffusion like other non polar like CO2 and water.However, glycine is an amino acid ( the simplest amino acid) a charged molecule /polar molecule/.it can not therefore pass through the bilayer by simple diffusion because of the phospholipid bi-layers. Therefore special transport proteins are needed for its passage across the cell membrane.

Example-GLYT 1 and 2 are the carrier proteins  specific for glycine transport across the membrane.

Which macromolecule is made up of nucleic acids ?

B. RNA
C. Fatty Acids
D. Protein

Answers

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

Why do sex-linked traits follow different patterns of inheratance than other traits

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.

Answers

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.

Explanation:

The stimulus interval has a profound effect on the contraction force of the muscle. In your own words explain what happened when the muscle was stimulated in rapid succession. At which interval did the volunteer's muscle twitches begin to merge together (summate)

Answers

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.
