Which statement correctly describes how an organelle contributes to the ability of the cell to perform life functions?
The lysosomes digest food and break down cell parts when they die and the cell membrane prevents all harmful substances from entering the cell. So, the correct options are C and D.
What is Cell?Cell is defined as the smallest unit that can live on its own and that makes up all living organisms and body tissues where the cell has three main parts: cell membrane, nucleus, and cytoplasm. The cell membrane surrounds the cell and controls the movement of substances into and out of the cell.
A single cell is itself an organism. For example, yeast or bacteria. Other cells acquire specialized functions soon after they mature which acquire unique functions when they mature. They cooperate with other cells and become the building blocks of multicellular organisms such as humans and animals.
Therefore, the correct options are C and D.

Since the elephant’s diet consists of play material only, where would the elephant get the missing element needed to make collagen (or any protein)?
Answer:
The elephant is a herbivores animal and feeds on plant material that consist of cellulose. Collagen is a type of protein that is absent in plant material and only found in skin, tendons, bones and muscles. The elephant also requires collagen to replace or repair their skin cell in every 2 weeks.
As elephants are unable to consume meat that contains collagen, they get collagen or protein from the plant material only with the help of bacteria or enzymes present in its guts. The bacteria having enzymes that helps in the breakdown of cellulose and access the proteins, fat or sugar present in the plant cell.
Elephants get collagen and other proteins from the vegetables they consume.
We can arrive at this answer because:
Collagen is essential for the maintenance of the skin.However, collagen is found in large amounts in meat.Few vegetables have collagen and elephants only feed on vegetables.However, the demand for collagen in the elephants' body is met by feeding on vegetables rich in cellulose and vitamin C.When cellulose is digested and vitamin C is used in the body, collagen production is stimulated.

Answer:
The seed which is buried deep in the soil won't germinate
because
it won't get sufficient oxygen / airit won't get sufficient sunlight and etc...Answer:
Seed that had been planted 10cm deep won't get enough sunlight and adding water to make it grow just makes the condition even worse.
Seed that had been planted 5cm deep might not get sufficient sunlight because the rays of the sun cannot pass through the soil.
Seed that is on the top of the soil might get carried away by the wind, or dried due to extreme sunlight, or might get carried away by a predator.
The air pressure at City A is 1,018 mb, and the air pressure at City B is 980 mb. What will most likely occur due to the pressure gradient present between City A and City B?
Answer:
There are three main causes of change in population: births, deaths and imigration flow. The Coronavirus has affected two of these three factors. The death rate has increased substantially since the pandemic hit. In under 6 months, more than 200,000 people have died. This drastic number of deaths in such a short amount of time is bound to decrease the population of the United States by a considerable margin. Immigration flow has also halted since the beginning of the pandemic. Travel bans and the close monitoring of borders has ensured that the number of immigrants entering the United States has decresed greatly.
Most likely the pressure gradient present between City A and City B that is City A is 1,018 mb, and City B is 980 mb, will - The high-pressure system at City A will create winds that blow toward the low-pressure system at City B.
A force exerted on a surface by the air above it as gravity pulls it to Earth is called air pressure or atmospheric pressure. Atmospheric pressure is commonly measured with a barometer.
it determines wind and weather patterns across the globewinds move from high air pressure to low air pressureIt leads directly to wind and influences the speed and direction of that wind.Pressure differences or gradients also affect larger weather systems like storms.Thus, Most likely the pressure gradient present between City A and City B that is City A is 1,018 mb, and City B is 980 mb, will - The high-pressure system at City A will create winds that blow toward the low-pressure system at City B.

B. A virus has a cell, a nucleus, and does not eat.
C. A virus does not eat, use energy, or have cells.
D. A virus does not have a cell, produces carbon dioxide, and uses oxygen.
A virus does not eat, use energy, or have cells. The correct option is C.
What is basically a virus?A virus is an infectious microbe made up of a nucleic acid segment (either DNA or RNA) surrounded by a protein coat.
A virus cannot replicate on its own; instead, it must infect cells and use host cell components to replicate itself.
Viruses are bundles of nucleic acid DNA or RNA encased in a protein shell called a capsid.
Viruses are the most abundant life form on the planet, according to some estimates; they are 10 times more numerous than bacteria.
Viruses could have evolved from mobile genetic elements with the ability to move between cells.
Thus, the correct option is C as a virus does not consume food, generate energy, or have cells..

What hypothesis was validated by using paleo-magnetism?
Question 8 options:
a) subduction
b) hot spots
c) seafloor spreading
Answer:
C). Seafloor spreading.
Explanation:
Paleomagnetism is characterized as the 'study of the account of direction and strength of magnetic fields of the Earth in sediments, rocks, etc.' The hypothesis that was authenticated by using this study would be 'seafloor spreading' by displaying that magnetic reversal as strips of rotating polarity in gradually disseminating seafloor. This description of magnetic stripping by employing paleo-magnetism made the scientists believe that alternate crusts are being frequently made under ocean/sea. Thus, option C is the correct answer.

Rabbits normally eat some grass as a food source. In a habitat, a new species of grass is introduced that out-competes most of the original species of grass. The new species of grass contains a chemical that is usually toxic and fatal to most rabbits. Assuming that all rabbits in this habitat will eat some of the new species of grass, how will the presence of the new grass most likely decrease the diversity of the rabbit population in this habitat?
Answer:
Well The Diversity will decrease.
Explanation:
If the Grass Is Toxic to the Rabbit than the rabbits will either die from eating the grass, or they will stop eating it and need to find a new food source. this will lead to the to the rabbits that are resistant to the toxic grass being able to reproduce more and therefor becoming more abundant.

Answer:
incomplete dominance because the fruit color of the offspring is an intermediate form of the parents' fruit color
Sry if I'm wrong, have a nice day.
The given image shows incomplete dominance because the fruit color of the offspring is an intermediate form of the parents' fruit color. The correct option is D.
What is incomplete dominance?When both alleles of a gene are only partially expressed at a locus, it is known as incomplete dominance.
This sort of gene interaction frequently produces an intermediate or distinct phenotype. Additionally called partial dominance.
Two other types of genetic inheritance are codominance and incomplete dominance. It basically means that no allele can prevent or stifle the production of the other allele through codominance.
Incomplete dominance, on the other hand, occurs when a dominant gene does not entirely block the effects of a recessive allele.
Fruit produced by two parents and fruit produced by one of their children are shown in the photo.
Because the fruit color of the offspring is an intermediate version of the fruit color of the parents, it is incomplete dominance.
Thus, the correct option is D.

property common to alkali metals: they react with water. How does the reactivity vary
among this group of elements? Why might patterns like this be useful to scientists?
Answer: This might be helpful because t is a good basis for organizing elements because each element has a unique number of protons and atomic mass is an indirect way of organizing elements by number of protons.
