B) abiogenesis
Abiogenesis is one of the modern evolutionary theories on how life originated. It used to refer to the now-discredited hypothesis of spontaneous generation. It was once believed that complex living organisms such as mice, maggots, etc. could arise spontaneously from nonliving matter.
5. A herd of zebras has 9 males and 62 females.
During a one-year period, 22 foals that are born
survive and 25 adults die. Six females join the
herd. Three males and 11 females leave the herd.
Has the herd reached its carrying capacity for this
ecosystem? How do you know?
O a. The herd has reached its carrying capacity
because the growth rate is negative.
Ob.The herd has reached its carrying
capacity because the growth rate
is positive.
O c. The herd has not reached its carrying capacity
because the growth rate is negative.
Od.The herd has not reached its carrying
capacity because the growth rate
is positive.
Answer:
Choice: (A) The herd has reached its carrying capacity because the growth rate is negative.
Explanation:
The herd has reached its carrying capacity because the growth rate is negative. Hence option a is correct.
What is ecosystem?Ecosystem is defined as a ecology's structural and functional unit where living things interact with one another and their surroundings. Healthy ecosystems maintain our soil, clean our air, control the climate, recycle nutrients, and give us food. They provide tools and raw ingredients for producing medicines and other goods. Major elements of many ecosystems include plants, animals, insects, microorganisms, rocks, soil, water, and sunlight.
Clumps can disperse in a region when there is an unequal distribution of resources like food, water, moisture, temperature, or other materials. More food supplies are available, finding a mate requires less migration for individuals, and organisms are better protected from predators.
Thus, the herd has reached its carrying capacity because the growth rate is negative. Hence option a is correct.

explain what natural selection is and how it occurs
Answer:
Natural selection is when an animal adapts to their environment to survive and produces more offspring. It occurs when the animal isn’t thriving in their environment and they make adaptions to where they can survive.
Explanation:
An example of natural selection is, a bird used to have a really thick and short beak. But to have more access to food they adapted to their environment and now have a long and skinny beak.

Emission lines are lines that are made when wavelengths of light are given off by cooling gases.
O True
O False
Answer:
Its FALSE on edge
Explanation:
When cooling gases emit light wavelengths, lines known as emission lines are created. The first people to notice constellations were the ancient Romans and Greeks.
What Emission lines that are made when wavelengths light?Monochromatic light has a single wavelength and is generated by lasers, which exploit transitions between two atomic energy levels to generate light with an extremely restricted range of wavelengths.
While emission lines refer to the lines of light produced by burning hot gas, absorption lines refer to the tendency of cool ambient gas to absorb the same lines of light.
Some light at specific wavelengths is scattered when it travels through the atmosphere's gas, producing darker bands.
Therefore, It is false that Emission lines are lines that are made when wavelengths of light are given off by cooling gases.

why virus is imortal?
Answer:
Strictly speaking, viruses can't die, for the simple reason that they aren't alive in the first place. Although they contain genetic instructions in the form of DNA (or the related molecule, RNA), viruses can't thrive independently. Instead, they must invade a host organism and hijack its genetic instructions.
Explanation:
Answer:
A flu is a virus and the reason that you have to get flu shots every year is because every time a virus enters a host it is mutated by the antibodies, cells and biology of that host, so it can be passed on to another host who may not be immune to every part of this NEW virus.

- Chromosomes are made of DNA that contain genes that control the production of ______ within the cell.
Chromosomes are made of DNA and contain genes that control the production of proteins within the cell, which is in Option 2, because the DNA contains the blueprint of the cell and the living organism.
What is the significance of DNA as a blueprint?The DNA acts as a blueprint in which all of the cell's information is stored, such as in the form of a gene, which is later expressed in the cell in the form of polypeptides, proteins, enzymes, and so on by the translation process, and controls and regulates the cell for various functions. DNA contains lots of genes, but not all of them are expressible.
Hence, chromosomes are made of DNA and contain genes that control the production of proteins within the cell, which is in Option 2, because the DNA contains the blueprint of the cell and the living organism.

Imagine a glucose molecule entering the cell membrane. Would that
molecule be able to reach the mitochondria faster if the cell had a smaller
volume or a larger volume? Explain.
Answer: THE TRANSPORT OF A MOLECULE FROM THE CELL MEMBRANE TO THE MITOCHONDRIA WOULD BE FASTER IN A CELL WITH A SMALLER VOLUME BECAUSE THERE WOULD BE LESS DISTANCE TO TRAVEL
Explanation:
I hope this helped
Glucose is a simple sugar that constitutes of carbon, hydrogen and oxygen atoms. It is the most abounding monosaccharide out of all the carbohydrates.
The glucose molecule will move actively to the mitochondria from the cell membrane if the membrane has a smaller volume.
The reason for the answer is:
Smaller the cell size less will be the covering space, hence the molecule will move less distance to reach its target.Mitochondria uses glucose molecules and generates carbon dioxide as the waste material.It is not always beneficial for the cell to be larger sometimes smaller cells can be more dynamic.Therefore, the glucose molecule will travel faster when the cell membrane has a small volume.

photosynthesis is when plants convert sunlight, water and oxygen into energy
photosynthesis is how plants grow
Answer:
Photosynthesis is when plants convert sunlight, water, and oxygen into energy.
photosynthesis is how plants grow
Explanation:
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities. This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water – hence the name photosynthesis, In most cases, oxygen is also released as a waste product. Most plants, most algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere and supplies most of the energy necessary for life on Earth.

compare and contrast coal and nuclear power. would you support either of both of these forms of energy technology. why or why not?
Answer:
I will give you a basic idea of what you should write in my opinion you should support neither of these forms of energy mainly due to the reason that both forms of energy pollute the world. instead we should focus on using renewable energy such as solar wind and hydro. furthermore coal and nuclear power are non-renewable resources which means that there is only a limited amount on the earth which brings up the benefit of having renewable energy as there is endless supply of it.
