Answer:
PROTEINS!
Explanation:
Amino acids, often referred to as the building blocks of proteins, are compounds that play many critical roles in your body. They're needed for vital processes like the building of proteins and synthesis of hormones and neurotransmitters.
Answer:
Proteins
Explanation:
Amino acids are the monomers, or the building blocks of proteins. There are 20 different amino acids that can make up proteins. The ribosomes in a cell perform protein synthesis and create proteins by assembling the amino acids, according to the DNA's genetic code. The proteins created are used for structure, growth, repair, maintaining pH, balancing fluids and more. In addition, they can be used as enzymes and hormones.

Which of the following does NOT create variation within a population?
a. mitosis
b. genetic shuffling
c. sexual reproduction (meiosis)
d. mutations
Answer:
d
Explanation:
because mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke.
Mitosis does not create variation within a population.
What 4 processes create variation within a population?
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis .
What is variation in population?Variation among populations refers to the level of differences between two or more populations.
Hence, A is correct option

In which way is primary succession similar to secondary succession?
Both occur where life already exists.
Both are gradual.
Both occur where no life exists.
Both involve creating soil.
Answer:
The answer is b and it is correct
Explanation:
took the test.
Primary succession similar to secondary succession as both are gradual. So, the correct option is B.
What are Primary and secondary succession?Both primary succession and secondary succession entail a long-term, slow process of ecological change. Primary succession refers to the emergence of an ecosystem in an environment devoid of life, such as bare rock or sand dunes.
The rebuilding of an ecosystem in an area where life once flourished but was disturbed or eliminated, as in the aftermath of a fire or human disturbance, is known as secondary succession.
Both forms of succession entail a gradual process of organism colonization, with early successional species fostering the establishment of subsequent successional species. While the process of primary succession includes the production of soil, secondary succession does not share this characteristic.
Therefore, the correct option is B.

Which of the following statements correctly describes the inheritance pattern of mtDNA?
En un juicio, se solicita una prueba de paternidad para esclarecer un conflicto donde dos hombres indican ser padres de dos adolescentes (un niño y una niña). Uno de los posibles padres no es hemofílico, mientras que el otro si que presenta esta enfermedad. Por otro lado, ni la mujer ni los hijos tiene hemofilia, aunque si que se ha detectado que la hija es portadora de esta enfermedad.
Answer:
The father is the hemophilic person
Explanation:
Hemophilia is a recessive genetic disorder that is linked to the X chromosome. This disease is associated with a congenital blood coagulation disorder.
Since hemophilia is linked to the X chromosome, females can be both heterozygous (mosaic expressing both alleles) and homozygous, while males always have hemophilia.
Examples that show between species DNA show , and give evidence of evolution.
Answer:
Evidence of evolution can be identified through fossil records, testimonial fossils, biography, anatomy, and embryology. An example of a species DNA is the peppered moth, whereby light-colored moths are eaten by birds, unlike the dark colored ones which seem to camouflage on dark backgrounds. Evolution changes the genetic makeup of a population over time and may happen on a large scale or small scale basis which affects either one of a few genes over a short period.

Why do you think it is important that our bodies can respond to stimuli around us?
Answer: it is important that our bodies can respond to stimuli around us because without it, you wouldn’t be able to detect and respond to changes in their internal and external environment. Cells called receptors, which detect stimuli (changes in the environment). The stimuli is part of our control system, it is very vital.

Use the Harris-Benedict equation to estimate your calorie needs. Show your calculations to explain how you arrived at your answer.
Answer:
The Harris Benedict Equation is a formula that determines the total daily energy expenditure (calories) using BMR with some activity factors.
Basal Metabolic Rate (BMR) is defined as the amount of calories one would burn without doing anything for 24 hours. It uses variables of weight, age, height and gender to calculate BMR.
BMR calculation = 447.593 + (9.247 x weight in kg) + (3.098 x height in cm) - (4.330 x age in years)
In Harris Benedict Equation, BMR is multiplied by activity factor to determine calories need.
The activity factors in Harris Benedict Equation are:
for no exercise = 1.2
exercise for 1 to 3 days/week or light exercise = 1.375
exercise for 3-5 days/week or moderate exercise = 1.55
exercise for 6-7 days a week or hard exercise = 1.725
exercise for 2 times training = 1.9
So, calculation for my calorie needs is as following:
BMR = 447.593 + (9.247 x 50 kg) + (3.098 x 164.592 cm) - (4.330 x 23 in years) = 974.945
Calorie needs = BMR x 1.55
= 974.945 x 1.55
= 1511.16 calories

2.They recognize specific pathogens.
3.They take dead cells out of the body.
4.They bind to specific pathogens.
Answer:
1.They produce white blood cells.
2.They recognize specific pathogens.
Antibodies protect the diseases by two ways by recognizing specific pathogen and by producing WBCs.
what are antibodies?Antibody, also known as immunoglobulin, is a protective protein generated by the immune system in reaction to the presence of an antigen, which is a foreign material. Antibodies are proteins that identify antigens and latch on to them in order to eliminate them from the body.Antibodies also produce white blood cells.They recognize specific pathogens.Hence the correct option is 1, 2.

PLS ANSWER ITS A TESTT !!!
Answer:
decreased ability to carry oxygen
Explanation:
A mutation can cause a defect in human hemoglobin, Which would result in - decreased ability to carry oxygen.
Hemoglobin is an iron-rich protein found in red blood cells that gives red blood cells their unique red color. Hemoglobin is the protein responsible for carrying oxygen in red blood cells.
A mutation in the hemoglobin gene changes the hemoglobin protein in a way that causes sickle cell anemia.Sickle cell disease is caused by mutations in the beta-globin (HBB) geneThis mutation leads to the production of an abnormal version of a subunit of hemoglobinThis mutated version has decreased ability to carry oxygenThus, a mutation can cause a defect in human hemoglobin, Which would result in - decreased ability to carry oxygen.

Fossil fuels have been used for years as a source of energy. Even though there are many negative issues associated with the use of fossil fuels, they continue tobeused to a great extent. This is most likely because
Answer:
These fuels are very efficient, it means that fossil fuel sources (oil, natural gas and coal) have high energy conversion rates, thereby they enable to generate important amounts of energy.
Explanation:
It has been shown that the overall efficiency of the conversion of fossil fuels to electricity is approximately 40%, while 60% of the energy produced is wasted during the process of combustion. However, it is important to note that the efficiency of renewable energies (i.e., geothermal, solar, hydroelectricity, wind and biomass) have been considerably increased in the last years.
