Community, also called biological community, in biology, an interacting group of various species in a common location. For example, a forest of trees and undergrowth plants, inhabited by animals and rooted in soil containing bacteria and fungi, constitutes a biological community.

Explanation:

The object that is used in relative dating is Index Fossil. Thus, option C is correct.

Fossil records are described as the position of found fossils all through the surface or the layers of the earth. The older the fossils are, the deeper it is found. Fossil records are also considered to be gathered information about the total number of the discovered fossils and the data obtained from them.

Fossil records are important guides to determine how life existed before. If you are to assemble a fossil, you will be able to see and tell the evolutionary changes that happened over the past years. Fossil records are evidences pointing out that life before is totally different from now.

Index fossils are fossils that are common yet were only present for a brief time. By comparing a rock layer to other rock layers, index fossils enable scientists to determine the relative age of a rock layer. Organisms that are still alive today yet have undergone little alteration over millions of years are known as living fossils.

Therefore, The object that is used in relative dating is Index Fossil. Thus, option C is correct.

Genes are segments of deoxyribonuceleic acid (DNA) that contains the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contains a person’s genes. Genes are contained in chromosomes, which are in the cell nulecus.

Explanation:

Answer:

quick answer

Explanation:

Both genes and chromosomes are inherited from our parents. Genes are like the instruction manual that put us together. They determine our biological predisposition. Chromosomes are the structures that contain our genes, but unlike genes they also determine gender. Chromosomes are made up of two tightly-wound sister chromatids.

Explanation:

brainliest plz?

The ecosystem which is most likely has the greatest biological diversity and therefore the highest sustainability is a rainforest that has many types of plants and animals. Therefore, the correct option is D.

An ecosystem refers to the biological community where the biotic as well as the abiotic components interact with each other and influence each other.

It encompasses all the living organisms in a specific area as well as physical and chemical factors that shape their environment such as air water soil climate and environment. They play an important role in functioning the earth's biosphere, as they provide a range of essential services.

The study of ecosystem and interaction between is components is referred to as ecology. Hence, the correct option is D.

Answer:

The dominant (light green) parent was heterozygote for the trait

Explanation:

According to Gregor Mendel in his law of dominance, an allele is said to be DOMINANT if it masks the phenotypic expression of another allele in a gene. The allele being masked is called RECESSIVE allele. In this case of a frog whose allele for light green color is dominant over the allele for brown color, the light green color allele (G) is dominant while the brown color allele (g) is recessive.

However, in a cross between that have light green frog and a brown frog, a small brown frog is produced. This is possible despite the green color being dominant because the genotype of the light green dominant parent is HETEROZYGOUS i.e. it contains both light green (dominant) allele and brown (recessive) allele.

Hence, when a gamete with recessive allele (g) is produced by the heterozygous light green frog (Gg), it mates with a recessive allele from the brown frog (gg) to produce a brown offspring (gg).

Explanation:

Evaporation occurs when air that is warmer than water comes into contact with the water's surface, hence option A is correct.

As a liquid transforms into a gas, evaporation, a sort of vaporization, occurs on the liquid's surface. For instance, a high concentration of the evaporating substance in the surrounding gas significantly slows down evaporation when humidity affects the rate of evaporation of water.

It takes in moisture from garden soil as well as the biggest lakes and seas, and the level of the water will decrease when it is heated by the sun.

Therefore, solar energy, or heat from the sun, is what causes the evaporation process to occur, hence option A is correct.
