17. What causes evaporation?
O Air that is unsaturated with water vapor comes into contact with the surface of the water
O Air that is cooler than the water comes into contact with the surface of the water
O Air that is warmer than water comes into contact with the surface of the water
O Air that is supersaturated with water vapor comes into contact with the surface of the water in
Evaporation occurs when air that is warmer than water comes into contact with the water's surface, hence option A is correct.
What is evaporation?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.

what happens when a person is infected with live pathogens
Answer:Once you're infected, viruses invade host cells within your body. They then use the components of the host cell to replicate, producing more viruses. After the replication cycle is complete, these new viruses are released from the host cell. This usually damages or destroys the infected cells.

which of the following is an object used in relative dating
A-Carbon 14
B-Daughter Isotope
C-Index Fossil
D-Parent Isotope
i know for sure it’s not A
The object that is used in relative dating is Index Fossil. Thus, option C is correct.
What is Fossil records?
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.

Compare and contrast chromosomes and gene
Answer:
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.

How is the earthworm limited by being a skin breather?
Answer:
Earthworms need oxygen just like humans, but they don't have lungs like we do. They have a special skin that allows them to “breathe” oxygen right through it. ... This means the amount of oxygen inside the earthworm will always be less (lower concentration) than the area outside of the earthworm (higher concentration).

Answer:
definitely D because a rainforest is extremely vast when it comes to different species
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.
What is ecosystem?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.

A frog that is dominant for its light green color mates with a brown frog and produces one small brown frog. How is this possible if the green color is dominate?
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).
16. In which of the following situations are the phenotypes of F2 offspring expected to follow
the ratio of 9:3:3:1?
a. monohybrid cross for two unlinked traits
b. a monohybrid cross for two closely linked traits
c. a dihybrid cross for two unlinked traits
d. a dihybrid cross for two closely linked traits
Answer:
C
Explanation:
The F2 offspring of a cross would follow the ratio of 9:3:3:1 only if the cross is a dihybrid for two unlinked traits.
There is nothing like a monohybrid cross for two traits. A cross involving two traits is a dihybrid cross. Hence, options a and b are out of the equation.
A dihybrid cross for two closely linked traits would produce F2 offspring in another ratio that is different from 9:3:3:1 depending on the linkage map.
Hence, the correct option is C.
