Answer:
The correct answer is - All of the above
Explanation:
Food is produced at every part of the earth as it may be found even in the parts that are darkest at night or at the part of ocean. Communication between mates can be done by signals that may sent to show interest in mating, Camouflage is the way to escape or hide by use of the light that may momentarily distract predators as it can camouflage the underbelly of the fish by lighting it up the same color of as the sea surface to make it invisible.
How are proteins and nucleic acids related?
Answer:
C) The structure of proteins is determined by nucleic acids.
Explanation:
Protein is a polypeptide-based molecule. Polypeptides are a type of biological molecule made up of chains of amino acids. Nucleic acid, which comprises deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), is a family of macromolecules made composed of long chains of polynucleotides (RNA).

Amphibians are not completely free to live on dry land because they can escape from predators by jumping into the water. their food organisms live in water. they obtain oxygen from water through gills. their reproduction depends on water. their ancestors were fish.
Answer:
they obtain oxygen from water through gills
Explanation:
Amphibians are a group of organisms renowned for their ability to live on land and water. They include frogs, toads etc. Despite their numerous adaptive features that enable them to survive on land, they can still not live independently of water or aquatic environment.
This is because a stage of the life cycle of most amphibians require water for respiration via their GILLS. Amphibians in their juvenile stage e.g. tadpoles rely on water for them to breathe. Adult amphibians make use of lungs and skin for respiration.

Natural selection
Answer:
Natrual selection
Explanation:
your welcome girlies <333
The concept illustrated in the flowchart is Natural selection. The correct option is 4.
What is natural selection?Natural selection is the process by which species evolve over time as the prevalence of certain traits increases or decreases in a population.
Natural selection, the mechanism by which species evolve over time, is depicted in the flowchart.
Overproduction of offspring causes competition for limited resources, resulting in a struggle for survival.
Based on their inherited characteristics, some people are better equipped to survive and reproduce than others.
These people are said to be "fit," and they are more likely to pass on their positive traits to their children. These advantageous traits become more common in the population over time, causing changes in the species as a whole.
Thus, the correct option is 4.

6. What do fungi have in common with animals?
Answer:
Fungi are more like animals because they are heterotrophs, as opposed to autotrophs, like plants, that make their own food. Fungi have to obtain their food, nutrients and glucose, from outside sources. The cell walls in many species of fungi contain chitin.

Complete question:
Frequently, a group of related species will each have a unique courtship ritual that must be performed correctly for both partners to be willing to mate. Such a ritual constitutes a ________ ________ reproductive barrier.
Group of answer choices
A) behavioral . . . prezygotic
B) mechanical . . . postzygotic
C) temporal . . . prezygotic
D) gametic . . . postzygotic
Answer:
A) behavioral . . . prezygotic
Explanation:
The biological concept of species states that individuals of a species can not mate and reproduce with individuals of another species. But if they get to reproduce, the progeny will not be viable or fertile. There will not be any reproductive success.
There are different reproductive isolation mechanisms, which are barriers that inhibit or interrupt the genetic flow between different species.
Reproductive barriers are isolation mechanisms that prevent mating between two or more species. The prezygotic mechanism avoids fertilization between individuals of different species, while the postzygotic mechanism impedes the zygote to develop and reach the adult stage.
There are different types of reproductive barriers.
Pre-copulatory o pre-ziygotic:
Ecological or by habitat isolation; Seasonal or temporal; Sexual o ethologic; Mechanic; Gametes incompatibility.Postzygotic mechanisms or barriers include
Hybrid inviability, Hybrid sterility, Hybrid reduced viability or fertility, Cytoplasmic interactions.Behavioral isolation is also known as ethological isolation or sexual isolation. This is a prezygotic barrier that refers to the fact that even when many species occupy the same area, they are not sexually attracted to each other, and might be rejected because of behavioral factors, not getting to mate. This mechanism includes courtship patterns or mating rituals and specific chemical signals that allow recognition between individuals of the same species.

do fertilised eggs divide to form a foetus
Answer:
yes
Explanation:
the chromosome number of the egg and and sperm are halved ,and are then joined together. the fusion of the the nucleus of the haploid male gamete with the haploid female gamete is referred to as fertization and the product of fertilization is zygote.
The diploid single zygote then divides repeatedly and develops to produce the offspring whose somatic cells are diploid.The zygote is the initial stage in baby development. It is also known as a fertilized ovum formed from the union of the sperm cell and the egg cell. Foetus refers to the final stage in baby development.
