A:
Cells
B:
Proteins
C:
Chromosomes
D:
DNA
Genes influence an organism's traits by coding for proteins. Therefore, option B is correct.
What are genes?Genes are segments of DNA that hold the instructions needed to create a single, usually protein-producing, molecule in your body. These proteins regulate how our body develops and functions; they are also in charge of determining many of our physical traits, like our eye color, blood type, and height.
the information connected to a certain characteristic of the organism is encoded by these on the strands of genomic material; the entire strand of DNA or RNA is made up of numerous genes, each of which contains information. DNA is converted into RNA and then RNA is converted into protein.
Genes influence an organism's traits by coding for proteins. Therefore, option B is correct.

Determine which are true of prokaryotic and eukaryotic transcription. In prokaryotic cells _____________; in eukaryotic cells ______________.
Answer:
This question is not complete as it lacks options. However, it can be answered by giving the general differences between eukaryotic and prokaryotic transcription.
Explanation:
Eukaryotes are organisms that possess a membrane-bound nucleus that harbors their genetic material while prokaryotes are organisms that lack a membrane-bound nucleus.
Transcription is the process whereby a DNA template is used to produce an mRNA molecule. Below are the common differences in the transcription of eukaryotic and prokaryotic:
- Transcription in eukaryoric cell occurs in a NUCLEUS while transcription in prokaryotic cell takes place in a CYTOPLASM
- Transcription in eukaryotic cell requires proteins called TRANSCRIPTION FACTORS while transcription in prokaryotic cell does not require TRANSCRIPTION FACTORS.
- Transcription in eukaryotic cells occurs differently from translation while transcription in prokaryotic cells is coupled with translation i.e occur simultaneously.
Which two phrases describe the motion of all the outer planets?
no rotation, slow revolution
fast rotation, slow revolution
north-to-south rotation, slow revolution
no rotation, opposite revolution
Answer:
B. Fast rotation, slow revolution.
The two phrases that describe the motion of all the outer planets are fast rotation and slow revolution. Therefore,the correct option is B.
Outer planets, such as Jupiter, Saturn, Uranus, and Neptune, have relatively fast rotational speeds, meaning they spin on their axis more rapidly compared to the inner planets like Earth and Mars.
However, their revolution around the Sun is slower, as they are farther from the Sun and require more time to complete one orbit.
All outer planets have a slower revolution around the Sun compared to the inner planets. This is because their larger orbital paths result in longer orbital periods.

Which example describes an adaptation of a blueberry plant in the summer? Buds begin to form. The leaves turn red. The plant is dormant. Berries and leaves are fully grown.
Answer:
Berries and leaves are fully grown.
Explanation:
Blueberry plants are native to the northern hemisphere and belong to the Vaccinium genera and Ericaceae family.
They are deciduous shrubs that that are grown in cold-weather regions. They exhibit winter dormancy, which they induce with exposure to hours of cold.
If the winter is not hard, the plants might flower during this season, but if not, they do it at the beginning of the spring.
Blueberry plants can adapt to variable climatic conditions. However, temperatures lower than 5ºC might damage the buds. And temperatures over 36ºC might also damage the fruits.
Sunny summers favor the fruit quality and avoid pathogen development.
The collecting season varies according to the plant variety, but usually, harvests are done from late spring to late summer.
During the autumn, leaves turn reddish before falling, and buds develop once the vegetative growth is over.
How have some rainforest plants adapted to receive enough sunlight? O by growing poisonous flowers O by growing giant, slippery leaves O by growing giant, bright flowers O by growing long, deep roots
Answer:
Well, one type of adaptation might be for a vine, lets say grows high into the canopy. It benefits from growing high up, so it can get more sun than growing below. Growing poisonous flowers are a protection from animals eating the fruits that the plants grow.

Why do you think it is necessary for there to be variation in a population in order for evolution by natural selection to occur?
Variations in the population are necessary because it allows some individuals to acclimate to the environment while sustaining the survival of the population.
What do you mean by Genetic variations?Genetic variations may be defined as the existence of differences in sequences of genes between individual organisms of a species.
Natural selection randomly favors or unfavors one genotype at a time. If there will not be any genetic diversity, it may lead to either extinction or population explosion of a particular genotype.
The genetic variations also depend on the relative fitness of a particular species. In order to resist at least one genotype of given species, genetic variations are important.
Therefore, variations in the population are necessary because it allows some individuals to acclimate to the environment while sustaining the survival of the population.

Based on the Nebular theory, which of these is a step in the formation of the center of a new planetary system?
A. evaporation of condensed gases due to heat
B. combination of condensed gases due to gravity
C. contraction of condensed gases due to nuclear fission
D. expansion of condensed gases due to nuclear fission
Answer:
The answer is the evaporation of water. As the gas begins to collapse, thermonuclear fusion as a result of the immense gravity at the center of the cloud results in the generation of immense heat and radiation that turns solids and liquid into gaseous form, close to the center of the cloud.
Explanation:
This resulted in the nuclear fusion of gases and dust to create the sun and planets at the outer flattened portion of the disk." The sun forms in the center of the cloud since the gravitation effect that drives thermonuclear fusion are strongest in this region. Planets form in the outer regions of the accretion disks where matter attract each other into clumps and gain even more gravitational pull to yank even more matter.
