Which of the following adaptations is characteristic of animals in the alpine biome?
Answer: just pick c
Explanation:
Animals in the alpine biome are adapted to the cold with insulating fur or fat and efficient oxygen use, and have compact body shapes to conserve warmth.
Explanation:An adaptation characteristic of animals in the alpine biome includes having thick fur or fat layers that provide insulation to retain body heat in the cold environment. Also, due to a scarcity of oxygen at high elevations, these animals may have adaptations that allow for more efficient oxygen uptake and use. Additionally, alpine animals are often robust and have shortened limbs, reducing their exposed surface area and helping to conserve warmth.

How do plants get nitrogen? by carrying out photosynthesis by absorbing it from soil by carrying out nitrogen fixation or by absorbing it through evaporation
Answer: by absorbing it from soil
Explanation:
Nitrogen is an essential element required by the plants for their growth and metabolism that is for the synthesis of amino acids, proteins, and nucleic acids. The nitrogen is present in the earth atmosphere for about 78%. The plants cannot directly absorb atmospheric nitrogen instead they are capable of absorbing and utilizing the compounds of nitrogen such as ammonia, nitrates and nitrites. The atmospheric nitrogen is absorbed and fix in the soil by soil bacteria into compounds of nitrogen which can be easily absorbed by the plant roots from the soil.
what is an advantage of our scientific naming system
Our scientific naming system or binomial nomenclature provides a universal, standardized way to name organisms and avoids confusion. It's unique to each organism and gives information about its position in biological classification.
Explanation:One major advantage of our scientific naming system, also known as binomial nomenclature, is that it offers a standard, universally recognized method for naming organisms. This system helps to avoid confusion, as many organisms might have similar common names in different regions or languages, but their scientific names are unique. For instance, a wolf in English is a lobo in Spanish, but in both languages, it's referred to scientifically as Canis lupus. Another advantage is that the scientific name gives us information about the organism's taxonomy. The first part of the scientific name refers to the genus the organism belongs to, while the second part distinguishes the species within the genus. This makes it easier to classify and study organisms.

suppose you observed the size of the deer population in an area. you discovered that over a 3 year period, the population changed in the following way: 40 deer were born, 18 deer died, 20 deer migrated into the herd, and 6 deer migrated out of it. calculate the growth rate, per year, of the population. be sure to consider changes brought about by immigration and emigration. show your work
To calculate the growth rate of the deer population over 3 years, we subtract the number of deaths and emigrations from the number of births and immigrations. The net change is 36 deer, and the growth rate per year is 12 deer.
Explanation:To calculate the growth rate of the deer population, we need to consider the changes brought about by birth, death, immigration, and emigration. Over a 3-year period, 40 deer were born, 18 deer died, 20 deer migrated into the herd, and 6 deer migrated out of it. The net change in population size is calculated by subtracting the number of deaths and emigrations from the number of births and immigrations. In this case, the net change is 40 (births) + 20 (immigrations) - 18 (deaths) - 6 (emigrations) = 36 deer. To calculate the growth rate per year, we divide the net change by the number of years, which is 36 deer / 3 years = 12 deer per year.

How is the DNA described and what does this mean?
Final answer:
DNA, or Deoxyribonucleic acid, is the hereditary material shaped like a double helix and contains the genetic instructions for the development, functioning, growth, and reproduction of all known organisms. It is organized into 46 chromosomes in humans. DNA's structure allows it to encode the information needed to build and maintain an organism, making it essential for inheritance, coding for proteins, and the genetic instructions for life.
Explanation:
Deoxyribonucleic acid, or DNA, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person's body has the same DNA. It is described as a double helix, which looks like a molecular spiral staircase, and in humans, it is organized into 46 chromosomes. This genetic material is responsible for storing and passing genetic information from one generation to the next.
Think of DNA as the blueprint for an organism, containing instructions for building and maintaining an organism's cells. It dictates everything from your eye color to the type of enzymes your body produces. Half of your DNA comes from your mother and half from your father, making your DNA unique except in the case of identical twins.
The central dogma of molecular biology explains that DNA is organized into genes, which specify the sequences of messenger RNA (mRNA). These mRNA sequences then determine the amino acid sequence of proteins, which make up your cells and perform numerous functions in your body.
Chemical equilibrium results if _____.
1. all reactants are used up
2. some products are removed
3. more reactants are added
4. forward reaction rate equals reverse reaction rate
Answer:
Option D, forward reaction rate equals reverse reaction rate
Explanation:
When there is no observable change in any chemical reaction, then it is said that chemical equilibrium has reached.
At this stage the concentration of both the reactants and products is constant and hence forwards rate of reaction becomes equal to the backward reaction rate. There exists no observable change in the properties of the system and its components
hence, option D is correct

What holds the base pairs of DNA together? A. Covalent bonding B. Double helix C. Ionic bonding D. Hydrogen bonding
Hydrogen bonding holds the base pairs of DNA together. Hence the correct the options are d.
The base pairs of DNA are held together by hydrogen bonding. DNA is composed of two long strands that form a double helix structure, and each strand consists of a sequence of nucleotides. These nucleotides contain nitrogenous bases, which are adenine (A), thymine (T), cytosine (C), and guanine (G).
The hydrogen bonds form between specific pairs of these bases: adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). These hydrogen bonds are relatively weak, allowing the DNA strands to unzip or separate during processes like replication and transcription, while still maintaining the overall structural integrity of the DNA molecule. This complementary base pairing is crucial for the faithful transmission of genetic information and the functioning of DNA in various biological processes. Hence the correct the options are d.

Where are the macronutrients located on a nutritional label? A. on the left B. on the top C. on the bottom D. on the right Please select the best answer from the choices provided.
The correct answer is option B. on the top.
The nutrition label is the table present on every edible item. This table shows the amount of the nutrients present in the edible item. There are standard protocols, which are followed to write the quantity type and amount. On the top of the nutrition label, after serving size, the macronutrients are listed. After macronutrients, the micronutrients are listed. On the left side, the type of nutrient is written and on the right side the amount of the nutrient present is written.
Macronutrients are important substances that are present on the top of a nutritional label.
Further Explanation:
Micronutrients are vital elements that are essential to the body for the development and survival of the body. The three main macronutrients are fat, carbohydrate, and protein. All the macronutrients play a crucial role in providing energy in the form of calories. Proteins are a type of macromolecule that has a different variety of functions for the cell. These are polymers of amino acids that are linked together by peptide bonds. The proteins serve as the bodybuilding molecules, as well as the enzymes that aid in several biochemical reactions in the body. Immunoglobulin is a protein that protects the body from a different type of pathogen, and also, insulin is a cell-signaling molecule. They offer almost four calories per gram to the body. Carbohydrates and lipids offer four and ten calories per gram respectively.
A person can collect information regarding micronutrients by analyzing the nutritional table of the edible product. All the manufacturers of the product follow the usual protocol to mark the type and amount of the nutrient. They are placed on the top of the nutritional table because they are essential for the body. The total quantity of the nutrient is printed on the right side and the type of the nutrient is printed on the left hand.

What type of mutations do not result in evolution?
-genetic mutations in reproductive cells
-somatic mutations
=mutations that have been inherited
Answer:
somatic mutations
Explanation:
"Not all mutations are evolutionarily important. Somatic mutations occur in body cells and cannot be passed down from parent to offspring. Cancer, for example, is a mutation of body cells which causes unrestrained growth. Although cancer can be deadly for an individual organism, it is not passed from one generation to another. Only mutations in reproductive cells, like eggs and sperm, matter in evolution because they can be inherited by offspring."
what goes wrong during the cell cycle in cancer cells?
Gene mutations cause cancer by speeding cell division or blocking normal system mechanisms like cell cycle arrest or programmed cell death.
What are cancer cells?Cancer is a disease that is caused when cells divide in an uncontrolled manner and spread into the tissues that are in close proximity to them. DNA can become damaged, which can lead to cancer. The majority of mutations that can lead to cancer occur in specific regions of DNA known as genes. Alterations of this kind are also referred to as genetic alterations.
There is an imbalance in the number of chromosomes present in many cancer cells; as a result, there may be an excessive number of chromosomes or an inadequate number. The term "aneuploid" refers to the state of these cells. During the process of replicating DNA, mistakes can happen, which can lead to mutations and even the potential development of cancer.

What is the name for the process in which an ovary releases a ripened egg each month
Ovulation is the name for the process in which an ovary releases a ripened egg each month.
What is an Ovulation?Ovulation is defined as the process in which a mature egg is released from the ovary, after its release the egg travels down the fallopian tube and remains there for 12 to 24 hours, where it can be fertilized.
The process of ovulation begins when the hypothalamus which is a part of the brain releases gonadotropin-releasing hormone (GnRH) which causes the pituitary gland which is told in the brain to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). Progesterone levels that peak 6-8 days after ovulation, even when the woman is not pregnant.
Thus, Ovulation is the name for the process in which an ovary releases a ripened egg each month.
