A ___________ determines which variations will survive to reproduce and which won’t.
Heredity
The likelihood of a genetic variant being passed down to the following generation increases if a trait is favourable and aids the individual in surviving and procreating (a process known as natural selection)
What is heredity ?The traits we inherit genetically from our parents and ancestors before them are referred to as hereditary traits. The possibility that you will have blue eyes is an example of heredity. Your likelihood of developing breast cancer based on family history is an illustration of heredity.
DNA (deoxyribonucleic acid), which makes up genes, contains instructions for how cells should function as well as the traits that distinguish each individual. Each of your biological parents contribute half of your DNA to you, and you might inherit a gene mutation from one or both of them. Sometimes, problems with the DNA cause changes in the genes.Learn more about Heredity here:

which of the statements is true of the gastric cavity of cnidarians? digestive enzymes released into the gastric cavity allow the consumption of whole prey such as fish. egestion occurs through an anus opposite the mouth opening. digestion takes place in the stomach after storage in the gastric cavity.
This sentence is true in the case of gastric cavity of cnidarians - digestive enzymes released into the gastric cavity allow the consumption of whole prey such as fish.
Extracellular digestion is carried out by cnidarians, in which the cells that line the gastrovascular canal receive the nutrients and enzymes split down the food particles. With only one opening, the gastrovascular cavity that doubles as both the mouth and the anus in cnidarians acts as their only digestive system. There is only one entrance in the central gastro-vascular cavity, which serves as both a mouth and a drain for waste. Digestion occurs both within and outside of cells.
Cnidarians consume food through their lips, and the coelenteron then breaks it down. Waste products are subsequently eliminated either via the mouth or via cell surface via water circulation, while nutrients are then sent to other parts of the body for use.

According to Chargff's rule adenine always pairs with thymine and guanine with cytosine.
The DNA is made up of two kinds of nitrogen base pairs purines and pyrimidines. Adenine(A) and guanine(G) are purines and thymine(T) and cytosine(C) are pyrimidines. The two nucleotide strands are held together by hydrogen bonds.
Erwin Chargaff in 1949 showed that
Adenine always pairs with thymine and guanine with cytosine.The total number of purine nucleotides is always equal to the total amount of pyrimidine nucleotide A+G=T+C.The proposition of adenine is equal to thymine and so guanine is equal to cytosine. But the [A]+[T] need not necessarily be equal to [G]+[C].These empirical rules regarding the composition of bases in DNA are collectively called the Chargaffs rule or Base pair rule.

transcription builds , whereas translation builds . a. dna; rna b. proteins; dna c. rna; proteins d. rna; dna e. dna; proteins
The correct option is (c). Transcription builds RNA, whereas translation builds proteins.
Transcription is the process by which the genetic information encoded in DNA is copied into a complementary RNA molecule. This process occurs in the nucleus of eukaryotic cells and in the cytoplasm of prokaryotic cells. Translation is the process by which the genetic information encoded in mRNA is used to synthesize proteins. This process occurs in the ribosomes of cells, using the genetic code encoded in the mRNA to determine the sequence of amino acids in the protein.
Therefore, transcription builds RNA, and translation builds proteins. The correct answer is therefore "c. RNA; proteins."

The special type of virus that fills a computer system with self-replicating activity, clogging the system so that its operations are slowed or stopped is a worm.
Unlike a virus that needs a host file to attach itself to, a worm can replicate and spread on its own, infecting multiple computers within a network. Worms often exploit vulnerabilities in operating systems and software to gain access to a system and can cause significant damage by consuming network bandwidth and slowing down the performance of infected computers.
To prevent the spread of worms, it is crucial to have robust security measures in place, such as a firewall that can detect and block unauthorized access attempts. It is also essential to keep the operating system and software up-to-date with the latest security patches to address known vulnerabilities. Moreover, users should exercise caution when opening attachments or clicking on links from unknown sources as these can be carriers of malware, including worms. By taking these precautions, users can reduce the risk of infection and protect their systems from the damaging effects of worms.

Answer:
stars spend most of their lives on the main sequence fusing hydrogen gas to helium gas. stars eventually swell up to form a red giant star. stars like the Sun end their lives as planetary nebulae and white dwarfs.
Explanation:
Answer:
The way a star dies depends on how much matter it contains—its mass. As the hydrogen runs out, a star with a similar mass to our sun will expand and become a red giant. When a high-mass star has no hydrogen left to burn, it expands and becomes a red supergiant.

protein synthesis is directed by a compound in the cell nucleus called ___________.
Protein synthesis is directed by a compound in the cell nucleus called DNA (Deoxyribonucleic acid).
DNA is a long molecule that carries genetic information and instructions for the development, function, and reproduction of all living organisms. The information encoded in DNA is stored in the form of a genetic code, which is made up of four nucleotide bases: adenine (A), guanine (G), cytosine (C), and thymine (T).
During protein synthesis, the genetic code is transcribed into messenger RNA (mRNA), which carries the instructions from the nucleus to the ribosomes in the cytoplasm. The ribosomes then use the mRNA code to direct the assembly of amino acids into a protein chain, according to the rules of the genetic code.
Overall, DNA is the key molecule that directs protein synthesis and the overall function and development of cells and organisms.

Explain how the result show that both light and chlorophyll must be present for photosynthesis.
Chlorophyll absorbs energy from blue and red light waves during photosynthesis while reflecting green light waves, giving the appearance of a green plant.
Chlorophyll, a light-absorbing pigment found in the thylakoid membranes of the chloroplast, is what gives plants their green hue. Chloroplasts, which are tiny organelles found inside plant cells, are there to store solar energy. Despite the fact that there are numerous steps involved in photosynthesis, there are primarily two stages: light-dependent reactions and light-independent reactions. The light-dependent reaction, as its name implies, occurs inside the thylakoid membrane and necessitates a constant supply of sunshine. The light waves' energy is captured by the chlorophyll and transformed into chemical energy in the form of the molecules ATP and NADPH.
The Calvin Cycle's light-independent stage, which takes place in the stroma, or region between the chloroplast and thylakoid membranes, does not require light, hence the name light-independent reaction. In this phase, carbon dioxide is converted into carbohydrates like glucose using energy from the ATP and NADPH molecules. However, not all types of photosynthesis are made equal. C3 photosynthesis and C4 photosynthesis are two of the various forms of photosynthesis. The majority of plants engage in C3 photosynthesis. It entails the Calvin Cycle producing 3-phosphoglyceric acid, a three-carbon molecule that later transforms into glucose.
