In prokaryotes, transcription and translation can happen simultaneously because DNA and ribosomes are both located in the nucleus. Therefore, option B is correct.
The ribosomes are responsible for protein synthesis. They are also found in the cytoplasm of prokaryotic cells. The ribosomes read the mRNA produced during transcription and directly synthesize proteins using the information encoded in the mRNA.
The absence of a nuclear membrane in prokaryotes allows for the coupling of transcription and translation to occur in close proximity in the cytoplasm.

write a letter to the government explaining the dangers posed by global warming/climate change
Answer:
Global climate change has already had observable effects on the environment. Glaciers have shrunk, ice on rivers and lakes is breaking up earlier, plant and animal ranges have shifted and trees are flowering sooner. Effects that scientists had predicted in the past would result from global climate change are now occurring: loss of sea ice, accelerated sea level rise and longer, more intense heat waves. Scientists have high confidence that global temperatures will continue to rise for decades to come, largely due to greenhouse gases produced by human activities. The Intergovernmental Panel on Climate Change (IPCC), which includes more than 1,300 scientists from the United States and other countries, forecasts a temperature rise of 2.5 to 10 degrees Fahrenheit over the next century.

What causes the appearance of the Moon to change over time?
A
The orbit of the Earth around the Moon and its distance from the Sun.
B
The Moon's position relative to the Sun and Earth as it revolves around
Sun.
с
The rotation of the Moon on its axis.
The distance of the Moon to the Sun.
D
Answer:
B
Explanation:
The reason we see different moon phases is because of how the sun, earth and moon are relative to each other .
Answer:
As the Moon orbits our planet, its varying position means that the Sun lights up different regions, creating the illusion that the Moon is changing shape over time. The best way of getting to understand the lunar phases is to regularly go out on a clear night when the Moon is in the sky and observe it.
Explanation:
Actually, the Moon rotates in the same period that it revolves, so we always see the same side (the white arrow keeps pointing to Earth). The differences in the Moon's appearance from one night to the next are due to changing illumination by the Sun, not to its own rotation.

a. Because it contains organelles
b. Because it is a single cell
c. Because it contains genetic material
d. Because it is much smaller
Answer:
Option a
Explanation:
A eukaroytic cell contains more organelles than prokaryotic cells, and it is much bigger and complex.
hope this helps and is right :)
The choice that identifies the eukaryotic cell for the correct reason would the presence of organelles. The correct option would, therefore, be A.
Eukaryotic cells differ from prokaryotic cells such that:
Eukaryotic cells have nucleus, prokaryotic cells do not. The genetic materials of prokaryotic cells lies freely within the cytoplasm.Eukaryotic cells have membrane-bound organelles while prokaryotic cells do not. In size, eukaryotic cells (10 - 100 microns) is much bigger than prokaryotic cells (0.1 - 5 microns).In the images, the organelles of the eukaryotic cells can be seen while the smaller size of the prokaryotic cell can also be observed.

Explanation:
An individual has the genotype Aa Bb CC Dd ee FF. How many different types of gametes could it produce in terms of unique allelic combinations of these genes?
Answer:
64
Explanation:
The individual in this question with genotype: Aa Bb CC Dd ee FF has six (6) different traits encoded by six (6) genes. The diploid number of the organism in this question is 12, however, the number of possible allelic combinations in each gamete can be calculated by using 2^n where n = haploid number of chromosome or number of allele that can be in one gamete.
Using this simple formula, 6 possible alleles can be in the gamete of this organism with the above genotype, hence, the individual can produce 2^6 = 64 different types of gametes in terms of unique allelic combinations of these 6 genes.
what is a allele in simple words
Answer:
An allele is one of two or more versions of a gene. ... If the alleles are different, the individual is heterozygous. Though the term allele was originally used to describe variation among genes, it now also refers to variation among non-coding DNA sequences.

The insect lays eggs, and the eggs develop into an insect that has colorful wings and long thin legs. What observations would you use to prove that the insect goes through complete metamorphosis? (2 points)
a
Observe at what stage the bugs are able to reproduce. If they reproduce quickly, they go through incomplete metamorphosis.
b
Observe how long it takes the insect to develop. The insect that goes through incomplete metamorphosis will develop quicker.
c
Observe how the insect changes as it develops. If the insect develops a cocoon, it is likely going through complete metamorphosis.
d
Observe what the insect eats over time. If it eats other bugs, it likely goes through complete metamorphosis please answer all I give brainlest
Answer:
1. c . The life cycles of insects and animals all start from a fertilized egg.
2. d . A bee goes through a pupa stage, while the grasshopper goes through a nymph stage.
3. b . I and II
Explanation:
The egg fertilization is very important for the emergence of almost all organisms. If the egg is fertilized then it will change into an organism otherwise no organism is produced from that unfertilized egg. The bees has four distinct life stages i.e. the egg, larva, pupa and adult whereas grasshopper has three stages i.e. egg, nymph, and adult. A moth and an eagle both start their life cycle as a fertilized egg and moth and an eagle both hatch from an egg which is laid by the mother outside of their body..
