Change TCA-GAT from DNA into mRNA
Answer:
AGU-CUA
Explanation:
An mRNA sequence is made using a DNA sequence as a template. The sequence is dictated by complementary base pairing.
DNA uses the bases A, T, C and G. A is complementary to T and G is complementary to C.
RNA uses the bases A, U, C and G. A is complementary to U and G is complementary to C.
When transcribing DNA to RNA:
C is paired with GG is paired with CA is paired with UT is paired with ATherefore, TCA-GAT is transcribed to AGU-CUA
if the prey population increases, the predator population will__
a.) increase
b.) decrease
Answer:
increase
Explanation:
The predator population will increase if the prey population increase because the predators will have more food. Hope I helped! Have a great day! ;)
a) increase.
Explanation:As the prey population increases, there is more food for predators. So, after a slight lag, the predator population increases as well. As the number of predators increases, more prey are captured. As a result, the prey population starts to decrease.
hope this help! sorry if im wrong

What appears to happen to the Moon as it goes through the phases?
Answer:
What appears to happen to the Moon as it goes through the cycle? The moon appears to change shape or get lighter and darker as it passes through its cyclic monthly phase. Why does the Moon look different at different times of the month? Moonlight is sunlight bouncing off the Moon's Surface.

Which of the following best describes how the cells formed during mitosis compare to the cells formed during meiosis? (1 point)
A)Mitosis produces four genetically identical cells, while meiosis produces two genetically different cells.
B)Mitosis produces two genetically different cells, while meiosis produces four genetically identical cells.
C)Mitosis produces two genetically identical cells, while meiosis produces four genetically different cells.
D)Mitosis produces four genetically different cells, while meiosis produces two genetically identical cells.
C
Because yes meiosis produces four genetically different cells (this cells are gametes or sex cells)
Is a cell membrane more like a brick wall or a chain-link fence? Why?
Answer:chain-link fence
Explanation:a cell membrane is partial permeable which means that it lets some substances through but not other.
Answer:
Chain-link fence
Explanation:
Cell membranes are barriers that decide which molecules enter and exit the cell, and how much of them come in. So things are able to pass through them.
If it were a brick wall, it would not let anything pass through.
So it is more like a chain-link fence, but with more control over what passes through it.
Which specialized cells act as a barrier to protect tissues within the body?
epithelial cells
neurons
red blood cells
smooth muscle cells

WEIRD QUESTION *not school related*
I stayed up 24 hours, studying for some biig tests coming up and I'm feeling groggy so I might take a nap later, but I don't want to sleep for like 10 hours, just like 3
but like, how do I pull that off?? set an alarm??? ask someone to wake me up??
Answer:
Set multiple alarms!1!!1!!1!1 When you go to bed put your phone far away so you'll have to walk to it to turn it off.
Explanation:
It's most likely you'll fall asleep and feel tired when you wake when you don't wanna wake up. Putting it at a distance and setting it multiple times in short times will help you wake up better as it can continuously make you more and more awake.

Describe how traits are inherited through traits sexual Reproductions
WILL MARK AND 5 STARS
Answer: sexual reproduction is the union of male and female gametes to form a fertilized egg, or zygote. The resulting offspring inherit one half of their traits from each parent. The process where haploid sex cells are created from diploid parents is called meiosis, and it occurs only in the reproductive organs.
Explanation:
i have advanced so this is what i got right
Answer: In sexually reproducing organisms, each parent contributes half of the genes acquired (at random) by the offspring. Individuals have two of each chromosome and hence two alleles of each gene, one acquired from each parent. These versions may be identical or may differ from each other.
A tightly coiled tube where sperm mature
Answer: Epididymis
Explanation: The epididymis is a long, coiled tube that rests on the backside of each testicle. It functions in the carrying and storage of the sperm cells that are produced in the testes.

À ________ is a segment of DNA which codesfor a specific trait
Answer:
The answer for the blank is= Gene
Answer:
A gene is a segment of DNA which codes for a specific trait.
Explanation:
Cellular development, replication, and cell repair are controlled by genetic information stored within DNA molecules. The long-chain, helical macromolecules of these deoxyribonucleic acids, are constructed from complex sequences of covalently bonded monomers called nucleotides.
Genes, can span several nucleotides and even multiple chromosomes. They are encoded through the processes of transcription, translation to become proteins, that determine physical characteristics or phenotypes.

Changes in inherited characteristics can cause a species to change into a new one. This change over time is called?
Answer:
Evolution
Explanation:
Evolution is the change in the inherited traits of a population from generation to generation. Mutations in these genes can produce new or altered traits, resulting in heritable differences (genetic variation) between organisms.

In the cells of most organisms, genetic information is contained in the:
A cell wall
B nucleus
C organelle
D all of the above
Answer:
The nucleus
Explanation:
Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA). Mitochondria are structures within cells that convert the energy from food into a form that cells can use.
