Answer:
The 2 ways abiotic factors affect biotic factors are as follows:
- An alligator submerges itself under water to stay cool in the summer.
- A naked mole rat creates burrows underground.
Explanation:
Abiotic Factors:
All non-living factors that is present or influences an ecosystem. Abiotic factors determine the dynamics of an ecosystem such as the terrain, the atmosphere as well as the inhabitant flora and fauna. Water, sunlight, oxygen, temperature, and soil are all abiotic factors.
Biotic Factors:
All living factors in an ecosystem i.e. the plants and animals.
Lets analyze all the options:
- A bird picking food out of an alligator's teeth is an interaction between 2 biotic factors, the bird and the alligator or in another case, the bird and the food.
- Water being oxygenated is an interaction between 2 abiotic factors: water and oxygen.
Photosynthesis. These are the reactants for photosynthesis and the products of cellular respiration.
Answer:
If a protein or molecule is taken up by the cell and must be digested it will make use of <u>lysosomes</u>.
Explanation:
Lysosomes are membrane-bound organelles that have a wide range of functions but their main 'job' is to break down large molecules into smaller molecules or to digest molecules that are present in excessive or unnecessary amounts. This is why <u>they contain important digestive enzymes known as hydrolitic enzymes.</u>
Lysosomes can break down, for example, large proteins into amino acids to provide the cell with the necessary nutrients.
Answer:
Seeds- form through <u><em>sexual </em></u>reproduction and contain an embryo that gives rise to a new plant.
Explanation:
The formation of seeds occur when a ripened ovule is fertilized by pollen. If the pollen and the ovule are from the same plant, then it is termed as self-pollination. If the pollen fertilizes the ovule of another plant then it is known as cross pollination. The seed contains the embryo which has the capability to form and generate into a new plant. Hence, the formation of seeds is a phenomenon which occurs in sexually reproducing plants.
Answer: The correct answer is It produces gametes that are needed for sexual reproduction.
Explanation-
Meiosis is a type of cell division, which is a characteristic feature of sexually reproducing organisms. It produces reproductive cells called gametes, which possess half number of chromosomes as compared to their parental cells ( which are diploid). Gametes from each parent fuse to form a diploid zygote that develops into an individual.
Thus, it summarizes the importance of meiosis to reproduction.
