The characteristic that makes marine mammals different from other marine animals is that they breathe air through their lungs. Thus, the correct option for this question is D.
What are the characteristics of marine mammals?The characteristics of marine mammals may significantly include they breathe air through the lungs, being warm-blooded, having hair (at some point during life), and producing milk to nurse their young — while also living most or all of their lives in or very near the ocean.
Marine mammals have the same characteristics as all other mammals, but they have adapted to living all or part of their life in the ocean. Many have streamlined bodies to help them swim faster. With similar to the Fishes and other animals that have gills so they can breathe underwater. Marine mammals do not have gills. They have to come to the surface to breathe.
Therefore, the characteristic that makes marine mammals different from other marine animals is that they breathe air through their lungs. Thus, the correct option for this question is D.

Why is it important for gametes to go through meiosis
Answer: Because Meiosis only occurs in reproductive cells, as the goal is to create haploid gametes that will be used in fertilization. Meiosis is important to, but not the same as, sexual reproduction. Meiosis is necessary for sexual reproduction to occ Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis also produces genetic variation by way of the process of recombination.ur, as it results in the formation of gametes (sperm and eggs). Hope this helps have a awesome day/night❤️✨

How much force would a shot putter need to make a 5.5 kg shot accelerate at 8 meters per so one squared
Answer:
44 N
Explanation:
Force applied can be calculated using the formula as follows;
F = m.a
Where;
F = force (Newton)
m = mass (kg)
a = acceleration (m/s²)
According to the information provided in this question, mass of shot put = 5.5kg, acceleration = 8m/s². Hence;
F = m × a
F = 5.5 × 8
F = 44 Newtons
The force needed by the shot putter is 44N.
What scientist used radioactive bacteriophages to prove DNA is the
hereditary material passed from one generation to the next?
Answer:
Alfred Hershey and Martha Chase
Explanation:
In 1952 Alfred Hershey and Martha Chase were working with bacteriophages or phages, which are viruses that infect bacteria. They knew that a phage had an outer shell of protein and an inner core of DNA. In addition, from the electron microscope observations, they also knew that during infection the virus attacks the bacterium by its tails and introduces its genetic material into the bacterium to multiply using its metabolic machinery. They radioactively labeled two sets of phages: one with 32P (which marks only DNA) and another with 35S (which marks only proteins). In two parallel experiments, they infected bacteria with viruses marked on their DNA and with viruses marked on their proteins. The cultures were shaken with a mixer to separate the virus particles from the bacterial coatings. They then performed a centrifugation to separate the phages from the bacteria, so that the larger and heavier bacteria remain in the pellet, while the phages remain in the supernatant. They found that the radioactivity of 35S appeared in the supernatant while that of 32P appeared in the sediment, from which new radioactively labeled virus particles appeared, demonstrating that DNA was the genetic material.

what is released in the light depended step of photosynthesis?
Answer: Imma say In the light-dependent reactions, which take place at the thylakoid membrane, chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water. The light-dependent reactions release oxygen as a byproduct as water is broken apart.The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron carrier NADPH. ... The photosystems and electron transport chain components are embedded in the thylakoid membrane.

Which of the following is NOT an ethical concern raised by genetic engineering?
A. Genetically engineered bacteria cells can be used to clean up mining waste and for sewage treatment
B. Creating organisms that are not naturally occurring may disrupt the environment
C. The question may need to be "should we" manipulate genes of organisms instead of "can we".
D. Creating plants with new genes may trigger allergic reactions
Answer:
The Answer Is A.
Explanation:
If They Can Be Used For Cleaning Up Mining Waste And For Sewage Treatment, That Makes Them A Good Thing. So It Wouldn't Be A Concern. Hope This Helps.
Genetically engineered bacteria cells can be used to clean up mining waste and for sewage treatment, which is not an ethical concern raised by genetic engineering. So, the correct option is A.
What do you mean by Genetic engineering?Genetic engineering may be defined as a process that involves the manipulation of the genetic material of organisms with help of lab-based technologies.
Bacterial species produced by genetic engineering used in cleaning up mining waste and sewage treatment benefit the atmosphere by reducing the level of waste and toxic compounds from suuroundings. So, it is not a matter of ethical concern.

describe how the skin works when the place is very hot
Answer:
when body temperature rises, such as when exercising on a hot day, the dermal blood vessels will dilate, in the sweat glands begin to secrete more sweat. the invaporation of the sweat from the surface of the skin cools the body by dissipating heat.
Explanation:
Hope this helped Mark BRAINLEST!!!
Answer:
When it is hot, we normally sweat. Sweating removes the heat energy from our skin. Our blood vessels open up which lets more blood flow. This allows a way for the heat to be lost. It lets your body cool down or try and cool down.
