Human, cat, whale and bat have similar forelimb bone structure with a different functions. These homologous structures show

Answers

Answer 1

Answer:

The correct answer is - that They share a common ancestor.

Explanation:

The bones of forelimbs of whale, bat, cat, and human are similar in structure due to the fact they are homologous organs. Such organs which have the same basic structure but play a different role in their respective bodies are called homologous organs.

These organs are developed from the same organization during their development but due to evolutionary change in their environmental condition and their requirement, these organs are modified to perform different functions. The homologous structures are end result of divergent evolution which means they show common ancestry.

A material was cooled from 100ºC to 40ºC. What is the temperature change?The specific heat of water is 4.18J/goC. I need the full explanation would mean a lot to me.

Answers

Answer:

-60°C

Explanation:

According to this question, a material was cooled from 100ºC to 40ºC.

The temperature change, which is symbolized by ∆T = final temperature - initial temperature

That is, ∆T = T2 - T1

In this question, T2 = 40°C, T1 = 100°C

Hence, ∆T = 40°C - 100°C

∆T = -60°C

Which of the following examples is a non-renewable source of energy A.Wind B.hydroelectric C.Nuclear power D.Wood

Answers

Answer:

An example of non-renewable source of energy would be C) Nuclear power.

Explanation:

Renewable resources include biomass energy (such as ethanol), hydropower, geothermal power, wind energy, and solar energy. Biomass refers to organic material from plants or animals, whilst Nonrenewable energy resources include coal, natural gas, oil, and nuclear energy. Once these resources are used up, they cannot be replaced, which is a major problem for humanity as we are currently dependent on them to supply most of our energy needs.

I hope this helps! Have a great day! -Olli :]

Nuclear power is a non-renewable source of energy. It is derived from the energy released by nuclear reactions, which are fueled by radioactive materials such as uranium or plutonium. Therefore, option (C) is correct.

What is nuclear power?

Nuclear power is a form of energy that is generated from nuclear reactions. It involves the use of radioactive materials, such as uranium or plutonium, which undergo nuclear fission in a reactor to produce heat. This heat is then used to generate steam, which drives a turbine and produces electricity. Nuclear power plants are used to generate electricity for homes and businesses, and they are typically very efficient and reliable sources of energy.

However, nuclear power also has potential drawbacks, including the risk of radiation leaks or accidents, the long-term storage of radioactive waste, and concerns over nuclear proliferation. Despite these concerns, nuclear power remains an important component of the world's energy mix, and ongoing research is focused on developing safer and more sustainable nuclear technologies.

Colorblindness is sex recessive A female who is heterozygous for -green color blindness normal male. What is the chance the boys wil be colorblind Do the Punnett Square!

Answers

Answer:

The correct answer is - 50% of boys will be colorblind.

Explanation:

Colorblindness is an X-linked recessive disorder which means it will affect a female if present in both X chromosomes whereas in males there is only one X chromosome so even one chromosome with the mutated gene will cause the disorder.

Cross: heterozygous female (XHXh) with a normal man (XHY)

gametes: XH Xh and XH Y

Punnett:

XH    XHXH   XHY

Xh    XHXh    XhY

Which one is more biologically disruptive a point mutation or a frameshift mutation

Answers

Answer:

Frameshift

Explanation:

A point mutation can be insignificant due to the genetic code, many amino acids come from similar codons (where one base can be incorrect and it results in the same amino acid). If it does change the amino acid, having only one different amino acid in a whole polypeptide chain usually does not cause a major problem.

However, a change in the reading frame can be a major issue because it changes every codon form what it should be. A frame shift mutation can even prevent the translation of a protein entirely if it effects the start or stop codon.

Terribly articulated, but the answer is 100% frameshift

The greatest delivery of oxygen from the blood to the surrounding tissues occurs at 37C. Colder blood temperature results in greater dissociation of oxygen and hemoglobin. Hemoglobin has a lower affinity for oxygen under high temperature conditions. Increasing blood pH results in more oxygen unloading in tissues.

Answers

Answer:

Option 3 (Hemoglobin.................conditions) is the correct statement.

Explanation:

In the given question, the graph seems to be missing. Please find the attachment of the graph below.

Everything just produces the main controller throughout the curve all through hyperphrenic disease, this implies the hemoglobin compatibility for oxygenation is affected by the heat intensity. When warming reduces sensitivity, the appreciation rises when the temperature lowers or drops.

There are other choices not associated with the condition. Thus, the response is the correct one.

Swirl the jar in a circular motion and watch the spinning motion of the liquid inside.


The student’s experiment demonstrates the formation of

A- blizzard due to the interactions between the hydrosphere and geosphere
B- hurricanes due to the interactions between the geosphere and atmosphere
C- tornadoes due to the interactions between the hydrosphere and atmosphere
D- thunderstorms due to the interactions between the hydrosphere and cryosphere

Answers

Answer:

Its C

Explanation:

-Ella-

The experiment performed by student only creates the vortex, caused by the interaction between the liquid and its movement in the jar. Therefore, none of the statements are true.

What is vortex?

The experiment performed by student involves mixing water, dish soap, and vinegar in a jar, thereby, creating a solution having a lower surface tension than plain water. Due to swirling of the jar, the liquid inside the jar spins creates a difference in surface tension between the center and the edges of the jar.

This effect is known as the vortex, caused by the interaction between the liquid and its movement in the jar.

The experiment by the student does not demonstrate the interaction between Earth systems. Blizzards and hurricanes occur due to interaction between the atmosphere and the Earth's surface, while tornadoes and thunderstorms occur due to atmospheric convection currents.

Therefore, only vortex is caused by the interaction between the liquid and its movement in the jar.
