Can a biotic factors be composed of cells

Answers

Answer 1

Answer: No because abiotic factors like water and temperature aren't made of cells. Water is made of atoms and molecules. Temperature is just a measurement.

Answer 2

Answer: yes, abiotic factors are the non living factors of the eco system and biotic factors are those in which are living in an eco system ,so you can differentiate easliy

What reproductive benefits do angiosperms have over mosses? This is for my biology course. It was a question on one of my assessments and I got it completely wrong. Can someone explain it to me so I can at least try to understand it?

Answers

Angiosperms are plants that flowers. In angiosperms, pollen allows sperm to be transported without the aid of water. On the other hand, mosses needs water so their sperm can swim and survive. Angiosperms are more capable of reproducing because the transport is much easier as compared to mosses.

Angiosperms are flowering plants. To start with, pollen allows the sperm to be transported without water. Mosses need water so their sperm can swim (moss sperm is flagellated), and the sperm can't survive being dried out. In angiosperms, the sperm cells are kept safe inside a pollen grain, and the pollen grain itself can be transported in a variety of different ways (e.g. wind, bees, birds, bats, etc.) The flower itself plays a role here, because it can attract pollinators. After fertilisation, the seed shells protect the embryos (seeds contain baby plants in a kind of dormant state), a secondary endosperm provides the embryo with food, and outside the seeds, you're going to have some kind of fruit. Fruits play an important role because they aid in the distribution of seeds. If a bird eats a berry, for example, there's a good chance that the seed will pass out the other end of the bird somewhere else and sprout into a new plant, or the bird might pick up some berries and drop them or even hide and forget them. Mosses don't have this option.

Sponges have...a. a coelom
b.tentacles
c. specialized cells
d. bilateral symmetry

Answers

Answer:

c. specialised cells

Explanation:

Sponges are invertebrates that belong to phylum Porifera. Most of them live in marine environment. They do not have true tissues or organs but specialised cells that perform specific functions for example porocytes, amoebocytes, pinacocytes and choanocytes. Porocytes control the water amount entering inside the sponge pores and choanocytes control the water movement inside the sponge body.

Sponges consume food via phagocytosis. They reproduce both asexually and sexually. They are sessile i.e. immobile.

Final answer:

Sponges have specialized cells that perform specific functions like filtering food and excreting waste. They do not have a coelom, tentacles, or bilateral symmetry.

Explanation:

Sponges have specialized cells. These cells are responsible for the various functions of sponges, such as filtering their food and excreting waste. Some examples of specialized cells in sponges are collar cells, which line the inside of the sponge and generate water flow, and amoebocytes, which transport nutrients throughout the sponge. Sponges do not have a coelom, tentacles, or bilateral symmetry.

n the F2 generation of Mendel’s crosses, all plants had the dominant trait. half of the plants had the dominant allele. all plants had both the dominant and recessive alleles. one in four plants had two alleles for the recessive trait.

Answers

The answer is one in four plants had two alleles for the recessive trait. In the F1 generation of Mendel cross, all of the offspring will be heterozygous. After two heterozygotes cross, in the F2 generation, one in 4 plants will have two alleles for the recessive trait, one in 4 plants two alleles for the dominant trait, and 2 in 4 plants will be heterozygotes.

Answer:
