Differentiating cells delete the dna for genes they do not need. a. True b. False

Biology
1 answer:
Anton [14]4 years ago
4 0
The answer is false

When the cells are differentiating in the embryo, they retain the same genetic material. However, certain genes in the differentiating cells are silenced using protein complexes called histones. This makes the genes inaccessible to RNA. Therefore, the process of transcription required in the expression of genes is restricted.

Miles wants to write the equation for photosynthesis. The diagram below represents one of the molecules in the equation. mc016-1
kvv77 [185]

Answer: C_6H_{12}O_6

Explanation: Photosynthesis is a phenomenon in which green plants containing chlorophyll use sunlight as a source of energy to convert carbon dioxide and water to form glucose and oxygen.

Photosynthesis is the process used by plants, algae and certain bacteria to convert energy from sunlight and turn it into chemical energy in the form of glucose which is used a s a source of energy by many organisms.

The balanced chemical equation for photosynthesis is written as :

6CO_2+6H_2O\overset{sunlight}\rightarrow C_6H_{12}O_6+6O_2

If dextrose is like the material of a plant's body, do plants also require energy to the process of building it?
kicyunya [14]

Answer:

To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. for photosynthesis. ... The energy from light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make the sugar (glucose) and oxygen gas.

no.

18. Which types of mutations, positive, negative or neutral, are most likely to be seen in offspring
Temka [501]
<h2>The following scenarios state whether the mutation is likely to be passed on to the offspring of the organism or not: </h2><h2> </h2>
  • a. A single bacteria cell contains a positive mutation in its DNA - The mutation is likely to pass as it is a unicellular organism with the cell itself containing the positive mutation.

  • b. A skin cell on a cat contains a positive mutation in its DNA - The mutation is not likely to pass as it is the skin cell.

  • C. A sperm cell in a whale contains a positive mutation in its DNA - The mutation is likely to pass as it is in the sperm.

Why is it wrong to say that bread is a compound?
tatiyna

Explanation:

Bread cannot be classified as a compound. Compounds are formed when two or more substances are bonded together chemically, however, mixtures are not chemically bonded.

Bread is a mixture of several compounds such as sugars, proteins, lipids and gases along with a culture of organisms or chemical leavEning agaent. Several of these components

Explanation:

Large chains of monomers form biological macromolecules which carry out many essential functions in the body these can include nucleic acids, carbohydrates, proteins and lipids. These are organic molecules, meaning they're ringed or long-chain Carbons bonded to the elements oxygen (O), hydrogen (H), nitrogen (N) and phosphorus (P).

  • Proteins are structural support molecules comprised of long chains of amino acids joined via peptide (CONH) bonds; these are 20 specific units that are arranged into several macromolecules. Amino acids are absorbed through digestion and are incorporated into the body’s cells to make up organs muscles signal molecules and an alternative energy source.                                                                 Basic makeup: C, H, O, N, S; polar C, O double bonds and N-H bonding
  • Carbohydrates function to supply energy and support molecules they consist of mainly sugars or starches in long chains and rings to form monosaccharide monomers. They include monosaccharides, disaccharides and polysaccharides which describes the type of bonding and the degree of complexity of the polymers.                Basic makeup: C, H, O -with many polar OH groups
  • Lipids function as energy storage and chemical messengers, these include fats, saturated and unsaturated fatty acids with double bonds and steroids and waxes. However, lipids are comprised of fatty acids and glycerol; they do not contain a fixed set of monomers, and unlike the other biological macromolecules, they are not polymers. The arrangement of hydrophobic heads and hydrophobic fatty acid tails can give these non-polar macromolecules hydrophilic and hydrophobic properties.                                                                     Basic makeup: C, H, O; non polar- a triple condensation reaction produces the molecules from a triple hydroxyl (OH) alcohol bonded to three long-chain carboxylic acids.
