Answer:
The correct answer is - expression of the dominant trait
Explanation:
The ineraction of the genes such as dominant and recessive trait are incorporated in the genes and not influence by the environmental condition. These interaction are by the de noo mutations or due to the error in gene expression.
The environmental conditions like toxins cause alteration or mutation in the gene expressions. Temeprature or epigentic conditions are also the factor the can cause influence to traits.

5. Knowing that acid rain has a pH of 2-3, would you conclude that crop species with a narrow soil pH range are in trouble? Is acid rain a problem for plant species and crops?
Answer:
Yes
Explanation:
Unless the crops acidity range is that of the rain( which it wouldn't be) it would throw off the crops Ph balance and harm it.
Yes, crop species with a narrow soil pH range are potentially in trouble due to acid rain. Acid rain can have harmful effects on plant growth and productivity. The acidity of the rain can change the pH level of the soil, making it more acidic and less hospitable for plants.
What is acid rain?Acid rain is a type of rain or other precipitation that is unusually acidic and has elevated levels of hydrogen ions (low pH). It is caused by the release of sulfur dioxide (SO2) and nitrogen oxides (NOx) into the atmosphere, which then reacts with water vapor to form sulfuric acid and nitric acid.
These acids can fall back to the ground as acid rain or other forms of precipitation and can cause harm to plants, animals, and infrastructure. Acid rain can also contribute to soil and water pollution and can have negative impacts on human health.
Acidic soil can also release toxic substances, such as aluminum, which can further damage plant roots and reduce plant growth. In addition, acid rain can damage plant foliage directly, leading to reduced photosynthesis and reduced yields.
So, acid rain can be a significant problem for plant species and crops, particularly those with a narrow soil pH range.

Answer:
D. 3H2O
Explanation:
An atom is the smallest unit of matter that has the characteristics of a chemical element. It consists of protons, neutrons, and electrons - small electrically charged particles.
They make up molecules - electrically neutral groups of two or more atoms connected by chemical bonds. Multiple molecules that consist of two or more different atoms make up a chemical compound.
The chemical compound that has nine atoms is 3H2O. Here, we have three molecules of water. Each molecule consists of three atoms - two hydrogen atoms and one oxygen atom. This means that three of these molecules have a total of nine atoms.

How did Watson and Crick learn about Chargoff's rules?
Answer:
Chargaff explained his findings and research to Watson and Crick at Cambridge.
Explanation:
Watson and Crick met Erwin Chargaff at Cambridge in 1952, where he explained his research and findings to them. His rule of parity, or 1:1 rule, stemmed from his discovery of guanine's equal ratio in pairing with cytosine.
Watson and Crick went in to use Chargaff's findings and the work of the researcher Rosalind Franklin as a basis for their work on DNA's double-helical structure.

An illustration of a circle with an arrowhead on the circle pointing clockwise. A black dot on the top left part of the circle is a dot with 4 vectors from it. Vector Z away from the center of the circle, vector Y toward the center of the circle, a vector tangent to the circle and clockwise labeled W and a vector labeled X along the circle and in the clockwise direction.
Which arrow represents the centripetal force responsible for this motion?
W
X
Y
Z
Answer:
The Answer is Y
Explanation:
Y is the arrow pointing towards the center of the circle and the centripetal force always goes toward the center of the circle.
The arrow that represents the centripetal force responsible for this motion is : Arrow Y
Direction of arrow YArrow Y points towards the center of the circle which is the same direction as the centripetal force acting on body whcih follows a curved path. centripetal force moves to the center of the circle ( i.e circular path ) of the object.

Which sequence describes the formation of a gamete?
A.transcription → replication → translation
B.replication → cell division I → cell division II
C.mitosis → cell division I → translation
D.cell division I → cell division II → transcription
Answer:
part c
Explanation:
The sequence replication → cell division I → cell division II describes the formation of gametes.
Where does the formation of gametes occur?Meiosis (reduced division), in which a germ cell splits into two pieces and produces four gametes, is the process by which gametes are created.
Meiosis is a type of cell division that results in the production of four gamete cells and a 50% reduction in the number of chromosomes in the parent cell.
The gonads are where gametes (germ cells) are made. This process is known as spermatogenesis in males and oogenesis in females. The majority of novel mutations arise during gametogenesis, however males exhibit a higher mutation rate.
