Every cell contains DNA. The main purpose of DNA is to store the cell’s genetic information. How does DNA control the cell?
A. DNA activates nerve signals in the nervous system
B. DNA speeds up chemical reactions and lowers activation energy
C. DNA protects the cell from invaders.
D. DNA determines what proteins are made.

Answers

Answer:

The answer is D: DNA determines what proteins are made.

Explanation:

The nucleotide sequences that make up DNA are a “code” for the cell to make hundreds of different types of proteins; it is these proteins that function to control and regulate cell growth, division, communication with other cells and most other cellular functions.This process is called protein synthesis.All known cellular life and some viruses contain DNA. The main role of DNA in the cell is the long-term storage of information. It is often compared to a blueprint, since it contains the instructions to construct other components of the cell, such as proteins and RNA molecules.

Hope this helps!! ;)

DNA controls the cell by determining what protein are synthesized by the cell. Thus, the correct option is D.

What is Translation?

Translation is the process of synthesis of proteins from the mRNA (messenger RNA) of the cell. This process occurs in the ribosome of the cell. In this process, the mRNA produced from the DNA encodes amino acids which join together to form large polypeptide and protein molecules.

mRNA are produced from DNA through the process of transcription. Transcription occurs in the nucleus of the cell. Through this process, DNA produces a sequence of mRNA which is complementary to it. This mRNA determines what proteins will be synthesized by the cell.

Therefore, the correct option is D.

If an organism is heterozygous for a particular trait, the organism
A.
has the same allele on both chromosomes in a chromosome pair.
B.
is missing alleles on the chromosomes in a chromosome pair.
C.
has different alleles on the chromosomes in a chromosome pair.
D.
has extra alleles on both chromosomes in a chromosome pair.

Answers

Answer: C.

has different alleles on the chromosomes in a chromosome pair

Explanation:

Hetero means different.

A heterozygous condition is one in which the child inherits various eye-color genes from both biological parents. For that particular gene, a heterozygous genotype exists when there are two distinct versions. Thus, option C is correct.

What is the particular trait for heterozygous organism?

When two distinct alleles of a gene (one mutant allele and one wild-type allele) are present in a diploid organism's cells, that organism is said to be heterozygous at that particular gene locus.

Heterozygosity describes a particular genotype, since the cell or organism is referred to be a heterozygote just for the particular allele in question.

The heterozygote may, however, occasionally have a phenotype that is somewhere between the phenotypes of both homozygous parents.

Therefore, has different alleles on the chromosomes in a chromosome pair.

Anaerobes carry on whereas aerobes carry on cellular respiration

Answers

Answer:

Anaerobes carry on cellular respiration in the absence of oxygen, whereas aerobes carry on cellular respiration in the presence of oxygen.

Explanation:

Many of the cell processes needed need some energy to occur. Cellular respiration is the process by which cells degrade organic compounds and turn them into energy. Cellular respiration follows two ways, which depend on the presence or absence of oxygen, and both of them begin with the process of glycolysis, which occurs in the cytoplasm and does not need oxygen to occur.

Aerobic Respiration

Occurs in the presence of free oxygen.Series of reactions by which pyruvic acid (product of glycolysis) turns into CO₂ and H₂O, producing many ATP molecules. Respiration occurs in the mitochondria.Takes place in two steps or stages: Krebs cycle and electron transporter chain. Glycolysis and Krebs cycle produce electrons, which then travel along the electron transporter chain while releasing energy, and ATP is produced.

Anaerobic Respiration

Occurs in the absence of free oxygenSeries of reactions by which using pyruvate (product of glycolysis) 2 ATP molecules van be produced. There are two ways in which anaerobic respiration can be produced: lactic fermentation and alcoholic fermentation. Lactic fermentation produces lactic acid and 2 ATPAlcoholic fermentation occurs in two steps, and the final products are ethylic alcohol, 2ATP, and 2 CO₂The whole anaerobic process occurs outside the mitochondria.

Identify the advantages and disadvantages of internal and external fertilization

Answers

When a sperm fertilizes an egg within the female, it is known as internal fertilization. The advantages of internal fertilization are that the fertilized egg is protected from predators and harsh environments, thus ending in higher chances of survival. Also, there is a lesser chance of desiccation of gametes. Disadvantages of internal fertilization are that there are lesser number of offspring produced at a given time because it is sometimes difficult for the male and female to come into intimate contact. Additionally, the risk of sexually transmitted diseases also increases.

With how many pieces did hestart? 100 points, questions on the picture James and Noel sat on the steps of their new house. It was going to be a hot day, but the boys preferred sitting outside to unpacking more boxes inside. Their mom was unpacking kitchen stuff, and the boys had grown tired of hearing her exclaim every time she unwrapped another of the teapots she hadn't seen in months. "You'd think she'd have enough teapots by now," said James. "Yeah," said Noel, "I don't get that excited about my Godzilla collection and that is way more interesting than any teapot." "And I'm sorry," said James, "but I know way too much about teapots for a boy my age." James then started listing all the things he knew about teapots. "There's the spout and the pouring angle," he began. But Noel had already tuned James out. The heat was rising and as tired as he was of his mother's teapots, he was more tired of James' complaining. Besides, there was a raggedy old dog down the street. Noel could tell, even from far away, this was a dog that belonged to no one. Its coat was matted. It had no collar. All he could see of the dog's face was its nose sticking out. Its coat was all brown, but a dirty, grayish brown, not the deep dark warm brown that made you feel safe. "And there's that teapot with the flowers. The brown one with the little dots all in a row," James continued on his rant, now listing all the teapots he had unwrapped for Mom. Noel continued ignoring James and watched the dog. It was moving slowly in their general direction. It stopped at various spots along the curb to smell things. Sometimes the smelling took a very long time. Every now and then it would sit down to scratch behind its ear. Noel wondered if it was looking for something to eat. James jabbered on and Noel began to wonder how a dog came to be in such a sad condition as this one. Did no one ever want it? Even as a puppy, was this fellow not cute enough to find a good family? Had it always been this ugly? Hadn't anyone ever been kind to it? The dog was across the street now, one house over. It seemed to be particularly attracted to mailboxes and the plants around them. To Noel's mind, it appeared that the dog was greeting each family on the street. Noel watched the dog cross the street heading in their direction. He hadn't noticed it before, but the dog's head seemed rather large. It swung back and forth in front of its body, much like the bears Noel had seen at the zoo and on television. Noel could not see any eyes through all the matted hair. He could see gnats and flies hovering over the poor thing, waiting for it to sit down again. It lumbered toward them. Noel noticed that James had stopped talking. He looked over at his brother. Staring at the dog, James seemed to be a bit shocked or surprised, maybe even stunned. "What is that?" James whispered. Instead of sniffing their mailbox and moving on like before, the dog started up the sidewalk toward the steps where they were sitting. Noel could hear the flies buzzing and see not just a few gnats, but a whole swarm around the dog. Bits of leaves and twigs hung in its hair. The dog continued toward them. Was it going to stop, wondered Noel. Should I get up and get in the house? But then, just when Noel felt a twinge of panic, the dog sat down, wagged its tail, and smiled. Noel had never seen anything like it before. It was as if the dog, flies and all, were posing for a photographer. It is going to be an interesting summer, thought Noel.Read these lines from the text:Noel could not see any eyes through all the matted hair.
