Answer:
A) Adaptation
As a scientific concept, race Group of answer choices A. is very significant because it gives us a clearer understanding of human behavior than the concept of culture provides. B. is evidenced by the exclusive possession of particular types of genes. C. aids in explaining human diversity. D. is not very significant because it gives us little insight into human behavior. E. Both B and D
Answer:
D. is not very significant because it gives us little insight into human behavior.
Explanation:
Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments.
As a scientific concept, race is not very significant because it gives us little insight into human behavior.
This ultimately implies that, race is a scientific concept that holds no significant or absolute value since the nineteenth century.
Hence, the difference between humans shouldn't be described based on race according to the United Nations Educational, Scientific and Cultural Organization (UNESCO).

What is located between each vertebrae
Answer:
A Disc (Intervertebral)
Explanation:
Answer:
An internal disk is located between each vertebra. A gelatinous substance called nucleus pulposus can be found in each disk, which provides cushioning to the spinal column.
Bumblebees show some ability to control their own body temperature. During cold weather, bumblebees have been observed warming their flight muscles by shivering. The bees are able to maintain a body temperature several degrees above that of the surrounding air. Regulation of their internal body temperature is an example of A. diffusion B. synthesis C. respiration D. Homeostasis
Answer:
D. Homeostasis
Explanation:
An endocrine system refers to a series of ductless glands and organs responsible for the production and secretion of hormones that are used by the body for the performance of various functions such as metabolism, controlling growth, reproduction, mood, sleep, etc. These hormones are secreted directly into the circulatory system (blood) and then transported to the organs and tissues in the body.
Basically, the endocrine system contributes significantly to the state of homeostasis in the body.
Homeostasis can be defined as a process through which a living organism maintains a steady or stable physical, internal and chemical environment that is ideal to enhance life and proper functionality.
Hence, regulation of the internal body temperature of the bumblebee is an example of homeostasis.
Answer:
Homeostasis

how would fossil fuel affect non terrestrial organisms?
Answer:
Explanation:
Drilling, extraction and burning of fossil fuels, endangers many desert biomes. Some deserts are used as dumping grounds for radioactive and chemical waste. Increasing dry periods and lack of vegetation from climate change can lead to more dust storms which further affect plant and animal species.
a) varigated
leaves accumulates less Food than non-varigated leaves under similar condition
Answer:
Due to less number of chlorophyll.
Explanation:
The variegated leaves accumulates or produces less amount of food than non-variegated leaves under similar condition because variegated leaves has number of chlorophyll as compared to non-variegated leaves. Chlorophyll is a green pigment that is responsible for the photosynthesis in plants, without chlorophyll no photosynthesis occurs in the plants. The variegated leaves has less number of chlorophyll as compared to non-variegated leaves which leads to less production of food in variegated leaves.
Wildfires in Crater Lake burned approximately 33,000 acres in 2011, leaving 25 square miles of charred

Answer:
QUESTION:
What happens to a cell when It receives the signal to begin apoptosis?
ANSWER:
Apoptosis begins when the nucleus of the cell begins to shrink. After the shrinking, the plasma membrane blebs and folds around different organelles. The blebs continue to form and the organelles fragment and move away from one another.

6. a) In what way is the genetic code in all organisms the same? (1 point)
Answer:
they all come from the same ancestor, and all organisms have DNA made of the same molecules that form our genetic code. DNA in every organism has the bases: A,T,C,G.
Also, don't use this if it's still June 2021 and you're doing ap ex, we might have the same teacher.
All living organisms use the same genetic code. This shows that all organisms share a common evolutionary history.
What is a genetic code ?The genetic code is the set of rules used by living cells to translate information encoded within genetic material into proteins. It is a sequence of three DNA or RNA nucleotides that corresponds with a specific amino acid or stop signal during protein synthesis.
The genetic code is universal. Living systems use nucleic acids and the same three-base codons to direct the synthesis of proteins from amino acids. For example, the mRNA codon UUU, codes for phenylalanine in all cells of all organisms.To know more about genetic code here

An ecologist is studying a newly discovered animal. The ecologist finds that it reproduces quickly and has many offspring each time it reproduces.
Which type of organism is it?
A. logistical
B. an r-strategist
C. a K-strategist
D. density dependent
THE ANSWER IS....
Answer:
B. an r-strategist
Explanation:
R-strategist (also known as r-selected species) refers to species whose population growth is based on the maximum reproductive capacity of the individuals under optimum environmental conditions (i.e., the biotic potential). These species are well known to produce numerous offspring and they show exponential population growth. The most common features of the R-selected species are 1-high reproductive rate, 2-rapid development, 3-early reproductive age, 4-small size, 5-short life spans, 6-poor competitive ability, and 7-high mortality. Some examples of r-selected species include rabbits, mice, marine invertebrates (e.g. jellyfish), weeds, bacteria, etc.
Answer:
Thanks so much for giving the answer!
It is r-stragery though.
k-stratergy produce fewer offspring slowly- such as an elephant.
r-strategey produce offsping rapidly- such as a (nasty) fly.

Answer:
The correct order of size - base pair < gene < chromosome.

Nitrogen base-pair attaches with the phosphate group and a sugar molecule to form a building block of DNA or nucleic acids. Nucleic acids make the gene is the physical and functional unit of hereditary that takes the information from parent cells to daughter cells.
Chromosomes are a structure that appears thread-like and makes the genome with different chromosomes. These structures are made up of wrapped DNA or genes around histone proteins.
When thinking about genotypes and phenotypes, which is the cause and which is the effect?
Answer:
A particular genotype does not necessarily guarantee a particular phenotype. Understanding what factors can change this expression is quite complex.. What is what i believe that above statement meant.
Explanation:
Error is the stochastic variation associated with a particular observation of the phenotype (and is managed by use of replication and and appropriate experimental design). The phenotype is the result not only of the average effect of the different alleles at a given locus across test units and across environments, but is impacted by the interaction between the different alleles and the environments (including genetic backgrounds) in which they are evaluated. Phenotype is not simply the sum of the genotype effect and the environment effect, as indicated in the mathematical formula that you provide.
