Answer:
#1. Angiosperms are the main food source for animals and provide oxygen for us to breathe. 2. living creatures Organic compounds (carbon-containing compounds, mostly carbohydrates) are used not only by the plant to synthesize cellular structures and power basic metabolisms, but often by other organisms.
Explanation:
Many animals depend on angiosperms for food because angiosperms are a significant source of food for animals and other living things because they make up the largest portion of the terrestrial environment in terms of biomass and number of individuals.
What is angiosperm ?The class of plants known as flowering plants, or angiosperms, are those that produce both flowers and fruits. The name "angiosperm," which refers to plants that generate their seeds inside a fruit, is derived from the Greek words angeion and sperma.
Angiosperms depend on animals to help disseminate their pollen and scatter their seeds, and animals depend on angiosperms for food (fruit, seeds, and leaves).
Angiosperms serve a variety of functions for humans, but food is by far their most crucial function. All grains, including wheat, rye, and corn, are taken from flowering plants. Angiosperms include starchy foods like potatoes and legumes like beans.
Thus, Many animals depend on angiosperms for food because angiosperms are a significant source of food.

✎﹏☾✦Describe the process of Binary fission in amoeba.
Answer:
Binary FissionThe type of asexual reproduction, in which the parent cell divides itself into two identical daughter cells by amitosis. The division of nucleus is called amitosis due to fact that the stages of a typical mitotic division are not observed in these cells. After division, the two daughter cells grow into adult ceils, e.g. Amoeba.
Binary Fission in Amoeba Amoeba reproduces by binary fission method where division of the parent cell and its components occur by stretching. The nucleus of parent cell grows and divides into two daughter nuclei (karyokinesis) by amitosis. Division of nucleus is followed by cytoplasmic division (cytokinesis). At the end of the process, two identical daughter cells are formed and identity of the parent organism is lost.
What are the major functions of the male and the female reproductive systems?
NO LINKS
Answer: These organs do the following jobs within your body: They produce, maintain and transport sperm (the male reproductive cells) and semen (the protective fluid around the sperm). They discharge sperm into the female reproductive tract. They produce and secrete male sex hormones. The human reproductive system functions to produce human offspring, with the male providing sperm and the female providing the ovum.

10. Many trees in temperate environments have broad, flat leaves. How does this leaf structure support the function of obtaining energy? a. A flatter surface allows more oxygen to enter the leaf b. A flatter surface allows more water to be retained in the leaf during periods of dryness. A larger surface area allows more light to reach the mesophyll where photosynthetic cells are locate d. A larger surface area allows more room for photosynthetic cells:
Answer:
A larger surface area allows more light to reach the mesophyll where photosynthetic cells are located.
Explanation:
A larger surface area allows more light to reach the mesophyll where photosynthetic cells are locate. So, the correct option is C.
What are Mesophyll cells?The mesophyll cells are defined as the inner ground tissue located between the two epidermal cell layers of the leaf that is composed of two types of tissue which are palisade parenchyma, an upper layer of elongated chlorenchyma cells containing large amounts of chloroplasts; and a lower layer of spongy parenchyma which is spherical or oval.
A major function of leaf mesophyll cells is to contain large populations of chloroplasts, which do the photosynthetic carbon assimilation that facilitates plant growth. Cells in the mesophyll which is the tissue between the upper and lower epidermis are uniquely suited to carry out photosynthesis on a large scale.
Thus, a larger surface area allows more light to reach the mesophyll where photosynthetic cells are locate. So, the correct option is C.

During meiosis, homologous chromosomes line up next to each other. In some
cases, one arm of a chromatid crosses over the arm of another chromatid. What is
the result of this process?
the independent assortment of genetic material
the creation of an additional sex cell
continuity in the offspring cell's DNA
additional variation in the DNA of each sex cell formed
Crossing over is a mechanisms involved in introducing genetic variation. When the arm of a chromatid crosses over the arm of another chromatid, it results in additional variation in the DNA of each sex cell formed. Option D.
---------------------------------------
Crossing-over between homologous chromosomes (prophase 1), the random lining of homologous chromosomes (metaphase 1), and random fertilization are the mechanisms involved in genetic variation.
The Crossing-over events occur between two homologous chromosomes in the equatorial plane and make the daughter cells genetically different from the original one.
The Chiasma is the position where two homologous chromatids interchange genetic information, giving a place for new genetic material or information to be provided to descendants.
After crossing over, homologous chromosomes get separated again.
So, according to this information, when the arm of a chromatid crosses over the arm of another chromatid, it results in additional variation in the DNA of each sex cell formed.

Explanation:
a population of animals is split in half by a river before speciation is completed the two halves are rejoined when a drought causes the river to run dry how would this impact the two populations
A. speciation would still occur because the two halves would be too different genetically to interbreed.
B. traits that had developed through mutation would still exist only in one of the halves.
C. the two halves would be reproductively isolated.
D. individuals could now freely mate, and gene flow would increase. (this took so long to write please clap)
Answer:
D. Individuals could now freely mate, and gene flow would increase.
Explanation:
Since genes/traits are passed on from parent to offspring the gene flow would definitely increase. Since the population of animals is now brought back together by the drought, they now have more mates resulting in more and different genes combining. Therefore, the gene flow would increase.

Answer:
The circulatory system of a human compared to that of a frog is different due to the number of chambers. A frog’s heart has three chambers (two atria, and a single ventricle), whereas a human’s has four (two atria, and two ventricles). The atrium of a frog receives deoxygenated blood from the blood vessels that drain the various organs of the body. The left atrium receives oxygenated blood from the lungs and skin.

Identify which of the following will easily pass through the membrane? A.) Protein Hormone B.) Steroid Hormone C.) Charged Ion D.) Water
Answer:
Hope this helps a bit, sorry if it doesn't. Have a good day/night! :}
Explanation:
Steroid Hormone: It is thought that, because of their lipophilic nature, free steroid hormones enter target cells primarily by passive diffusion through the cell membrane. After gaining entry to the cell, steroid hormones act as ligands for nuclear receptors and alter gene transcription
Protein Hormone: Small uncharged molecules can diffuse freely through a phospholipid bilayer. However, the bilayer is impermeable to larger polar molecules (such as glucose and amino acids) and to ions. These molecules pass across membranes via the action of specific transmembrane proteins, which act as transporters.
Water/Ion: Small polar molecules, such as water and ethanol, can also pass through membranes, but they do so more slowly. On the other hand, cell membranes restrict diffusion of highly charged molecules, such as ions, and large molecules, such as sugars and amino acids.
A substance that will easily pass through the membrane is: B. steroid hormone.
What is a membrane?A membrane can be defined as the thin layer that separates the ineterior of a living cell from another, especially by forming its outer boundary or layers.
This ultimaetly implies that, a membrane provides protection for a living cell or an internal cell compartment from its environment.
In conclusion, a steroid hormone is a substance that will easily pass through the membrane.
