Answer:

animals

mammals

vertebrate

Explanation:

cows have a backbone so they are a vertebrate

cows have hair so they are mammals

and the are animals just like every other living thing

Three terms used to describe organisms such as cows are:

An organism, especially a cow, is a living thing. An organism is a singular living being that exhibits characteristics of life, such as the ability to develop, reproduce, respond to stimuli, and preserve homeostasis. Mammalia, a class of multicellular organisms including cows, forms the animal kingdom. Cows are complex biological entities with specialized sensory and digestive systems that enable them to live and thrive in their environment.

The following three terms are used to describe cow-like creatures:

Cows are mammals, which are warm-blooded animals with hair or fur and the ability to feed their young with milk.

Herbivores: Cows are herbivores, which means they only eat plants and no animal products like meat or dairy.

Cows are included in the class of herbivorous mammals known as ruminants, which have a four-chambered stomach.

Therefore, three terms used to describe organisms such as cows are:

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.

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:

Taxonomy

Explanation:

Taxonomy is a system of classification that helps scientists identify and name living and nonliving organisms.

Taxonomy in biology organizes the natural world into groups with shared traits.

Answer:

When it multiplies in the nervous system, the virus can destroy nerve cells (motor neurons) which activate skeletal muscles. These nerve cells cannot regenerate, and the affected muscles lose their function due to a lack of nervous enervation.

Answer:

18 chromosomes

Explanation:

If the sperm of a boa constrictor has 18 chromosomes, the number of chromosomes that each skin cell of the snake will have is 36 chromosomes.

Meiosis is the process of gamete formation where each daughter cell or gamete contains half the number for f chromosomes as the parent cell.

According to this question, the sperm of a boa constrictor has 18 chromosomes. The sperm is a gamete formed as a result of meiosis.

Therefore, If the sperm of a boa constrictor has 18 chromosomes, the number of chromosomes that each skin cell of the snake will have is (18 × 2) = 36 chromosomes.

Explanation:

The sequence replication → cell division I → cell division II describes the formation of gametes.

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.

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.

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.

Answer:

The application of the word translation makes sense at the time of describing the synthesis of protein as the language of nucleic acids is transformed into the language of polypeptides by the phenomenon of translation. On the other hand, it will not be suitable to describe the synthesis of mRNA using the word translation as the nature of the biomolecule stays similar because both the DNA and the product of DNA, that is, mRNA are nucleic acids.
