Which statement explains why the structure of sickle cells differs from normal red blood cells?
a. The gene mutation affected protein synthesis.
b. The gene mutation prohibited DNA replication.
c. The gene mutation inhibited the cell's ability to produce tRNA.
d. The gene mutation affected the cell's ability to produce ATP.
Answer:
A. the gene mutation affected protein synthesis
Explanation:
Basically, sickle cell results due to point mutation (change in one nucleotide) in DNA, which in turns affects the mRNA produced and finally the protein made from that mRNA is affected. I have listed a helpful image below which shows that the mutation actually results in formation of an undesired protein which causes sickle cell to occur.

what is photo synthesis ?
[tex]\sf\purple{Photosynthesis}[/tex] is a process by which phototrophs convert light energy into chemical energy.
The word “photosynthesis” is derived from the Greek words "phos" (which means “[tex]\sf\pink{light}[/tex]”) and "σύνθ-εóîς" (which means “[tex]\sf\red{combining\:together}[/tex] .”) And so it means “combining together with the help of light.”
The process of photosynthesis occurs in green plants (the primary producers in a food chain) and a few other autotrophic organisms such as cyanobacteria, purple bacteria and green sulfur bacteria.
Following is the photosynthesis formula:
6 CO2 + 6 H2O —> C6 H12 O6 ([tex]\sf\blue{glucose}[/tex]) + 6 O2 ([tex]\sf\pink{oxygen}[/tex]).

why might scientists be wary of the results of a single experiment testing a particular treatment, even when the results are peer reviewed and statistically significant
Answer:
The results may not be true for humans if the experiment used a model organism.
Explanation:
An animal model is an animal species used in research that mimics diverse human traits/features such as, for example, human response to certain diseases. Thus, animal models may provide useful information related to human developmental biology and human diseases (i.e., prevention, diagnosis, treatment, etc). However, in general, experiments involving animal models cannot be used to predict human outcomes. For example, in genetics, animal models exhibit different features to humans, including but not limited to genomes (i.e., different number and structure of chromosomes), genes, gene regulatory pathways, epigenetics gene regulatory mechanisms, etc. In consequence, animal tests may be unreliable and therefore their results cannot be directly extrapolated to human subjects.

Explanation:
A ___(J)_____ is a group of individuals of the same species that mate and produce offspring. In each generation, new genotypes occur that express themselves as specific individual ____(K)___. Any factor that affects the ____(L)___ of a population can change the frequency of ___(M)___, resulting in evolution over time. Through the processes of variation and ___(N)___, new species can arise. A ___(P)___ is a population of physically similar, interbreeding organisms that do not interbred with other such groups.
Answer:
(J) population; (K) phenotypes; (L) gene pool; (M) alleles; (N) natural selection; (P) species
Explanation:
A population is a group of organisms living in a particular geographical area that is capable of interbreeding, while a species is a group of populations that are capable of interbreeding and producing fertile progeny. In a population, genetic variation can enter from one of these sources: 1-recombination (i.e., the exchange of DNA between homologous chromosomes during meiosis), 2-mutations (i.e., genetic alterations resulting from DNA replication), 3-migration of individuals between populations, or 4-lateral or horizontal gene transfer (i.e., the acquisition of genetic material between individuals without direct vertical inheritance, it is extremely rare in higher organisms). Alleles are gene variants which are may be created, for example, through mutation, while the gene pool refers to the total genetic diversity (i.e., alleles) that exists within a population. Finally, natural selection refers to the evolutionary process of differential reproduction and survival through which populations adapt and change.
The _____ of a species is usually the result of predation, competition, and other types of interaction between species.
Answer: Realized Niche
Explanation:
Realized niche is also referred to as Post Competitive niche and can be defined as a thriving environmental area created by a group of organisms to survive from an exsisting Faundermental niche where interactions (predation, competition, light, water,food) with other organisms were limited and competed for.
For example. In a tree( Faundermental niche) which houses different species of birds, In order to survive, each specie of the birds will create a realized niche so as to survive from predation, competition, light etc which the whole tree provides.
When the particles are equally spaced apart they have reached:
A. Hypertonicity
B. Dynamic Equilibrium

Answer:
B. Dynamic Equilibrium
Explanation:
The result of diffusion is a gradual mixing of material such that the distribution of molecules is uniform. Since the molecules are still in motion, but an equilibrium has been established, the end result of molecular diffusion is called a "dynamic equilibrium".
Answer:
B. Dynamic Equilibrium
Explanation:
When the particles are equally spaced apart they have reached Dynamic Equilibrium.
Mold is made up of many fungi cells. Mold would be considered what type of organism?
A. unicellular
B. prokaryotic
C. multicellular
Answer:
The answer is Multicellular
Mold would be considered a multicellular organism, which is made up of many fungi cells.
When it is said that living beings are made up of cells, what is meant is, if they are multicellular organisms.
Eukaryotes include all members of the animal and plant kingdoms, including fungi, which exist both in multicellular forms (molds) and in unicellular forms (yeasts), and protozoa, which are exclusively single-celled.
About multicellular organism molds:
The filaments that make up the mycelium are called hyphae. The hyphae may be separated into generally multinucleated sections by means of perforated septa, or may be absent.The cell wall of the mycelium of molds resembles an extensive tubular system through which the cytoplasm advances to disperse and search for nutrients.Therefore, we can conclude that mold would be considered a multicellular organism, which is made up of many fungi cells.

Answer:
Arterioles - D
Arteries - C
Veins - B
Capillaries - A
Venules - E
Explanation:
This question is describing the blood vessels that make up the circulatory system. The blood vessels with their accurate description are as follows:
- ARTERIES: Arteries are the most elastic and thick-walled blood vessels that functions to carry blood away from the heart using great pressure. Arteries are muscular, flexible tubes that carry oxygenated blood away from the heart to the arterioles.
- VEINS: Veins are blood vessels that carry deoxygenated blood back to the heart. Veins have a thin wall and are less elastic in comparison with arteries.
- CAPILLARIES: Capillaries are smallest blood vessels designated to connect the smaller arteries or arterioles to venules. They are also thin-walled.
- ARTERIOLES: Arterioles are small arteries or branches of an artery that connects the arteries to capillaries. Arterioles deliver blood to capillaries.
- VENULES: Venules are tiny veins or branches of a vein that connects the veins to the capillaries. Venules deliver blood from capillaries to veins.
