Explanation:

Explanation:

carbon dioxide is added are the atmosphere naturally with organisms respire or decompose carbonate rocks are weathered,forests fires occur,and volcanoes eript.Carbon dioxide is also added to the atmosphere through human activities, such as the burning of fossils fuels and forests and the production of cement.

let me know if u got it right

From the options the action that does not add CO₂ to the atmosphere is : ( B ) Planting trees

When Trees are planted more oxygen is added to the atmosphere, during photosynthesis because plants releases Oxygen into the atmosphere during photosynthesis.

Cooking with gas releases CO₂ into the atmosphere while burning up the gas to generate heat. For a material to burn in nature it utilizes oxygen from the atmosphere while adding Carbon into the atmosphere.

Hence we can conclude that the action that will not add CO₂ into the atmosphere is Planting trees.

Answer:

C

Explanation:

I guess it's C but not conform

C. An allele is never independently assorted and passed down randomly.

Alleles are found at the same place on a chromosome, known as a locus. They can have a dominant and recessive form, meaning that one form of the allele may be expressed over the other in the phenotype of an organism. An allele is one of two or more forms of a gene, which are variations of a particular gene that can produce different traits in an organism.

However, alleles are not always passed down randomly. In meiosis, the process of cell division that produces gametes (sex cells), the alleles of a gene are independently assorted and passed down to the offspring. This means that each gamete receives one copy of each allele at random, which can result in a mix of alleles in the offspring. However, the exact combination of alleles that an offspring receives depends on the combination of alleles that its parents had, which can influence the probability of certain alleles being passed down.

Answer:

Aerobic breathing disrupts glucose and combines disintegrated products with oxygen that generates water and carbon dioxide. The carbon dioxide is a waste of aerobic breathing because there is no demand for cells.

Cellular respiration reactants:

Glucose and oxygen.

Cellular Respiratory Products:

CO2 and water (H2O); ATP & Heat

Anaerobic breathing:  breathing occurring in the absence of oxygen that makes certain ATP still alive to cells.

Explanation:

Cellular Respiration is the mechanism that releases energy in the presence of oxygen by breaking down food molecules.

Cellular breathing = Aerobic breathing

In mitochondria, aerobic breathing takes place.

Some of the energy generated by food decomposition is stored as ATP and some as heat.

ATP is an energy storage molecule used by every cell as its source of energy.

Answer:

Plasma membrane, cytoplasm, ribosomes, and DNA.

Explanation:

There are what eukaryotes and prokaryotes have in common.

Answer:

The cell would no longer be able to produce proteins.

Explanation:

A cell contains around 10 million ribosomes; these ribosomes are organelles that create proteins so, without ribosomes, cells would not be able to produce protein further going on they would not be able to function properly.

Answer:

By radiometric dating

Explanation:

The relative age of a rock sample is determined by comparing a  (or the fossils it contains) to other layers. Relative age of a rock sample can be determined by looking at the position of various rock layers.

Absolute age of a rock sample is the numerical.  Absolute age can be determined by using radiometric dating.

According to Oxford dictionary, radiometric dating is "a method of dating geological specimens by determining the relative proportions of particular radioactive isotopes present in a sample."

Answer: Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water

Answer:

Artificial selection is the process by which humans choose individual organisms with certain phenotypic trait values for breeding. If there is additive genetic variance for the selected trait, it will respond to the selection, that is, the trait will evolve. All of our domesticated species, including crop plants, livestock, and pets, are the products of artificial selection for desirable traits, such as seeds and fruits that do not disperse readily, increased meat and milk production, and docile behavior.

Answer:

C. Hope this helps!!

Explanation:

The result of photosynthesis as glucose and oxygen is basically products. The correct option is B.

Photosynthesis is a process that plants and other organisms use to convert light energy into chemical energy that can then be released to fuel the organism's activities via cellular respiration.

Photosynthesis is important because it is the process by which plants convert carbon dioxide into oxygen using sunlight.

Animals require oxygen to survive, and plants serve as nature's air filter, filtering out harmful carbon dioxide.

Plants absorb carbon dioxide (CO2) and water (H2O) from the air and soil during photosynthesis.

Water is metabolized within the plant tissues, which means it ends up losing electrons, whereas carbon dioxide is reduced, which means it gains electrons. This converts water to oxygen and carbon dioxide to glucose.

Thus, the correct option is B.

The main biomolecules present in the meal are carbohydrates but there are also proteins and lipids.

First of all starch will be hydrolysed in the mouth.Saliva contains an enzyme called amylase that turns starch into dextroses and maltose.

In the stomach the HCl will activate the pepsinogen and it will become pepsin that will hydrolise proteins to albumoses and peptones.

Also in the stomach an enzyme called gastric lypase is present which turns lipids into glycerol and fatty acids.

In the duodenum:The pancreas releases pancreatic amylase which turns starch into maltose. It releases pancreatic lypase which turns lipids into fatty acids and glycerol. It releases proteolytic enzymes(trypsin, chemotrypsin, carboxypetidase, elastase, collagenase) which turn proteins, albumoses and peptones into oligopeptides(3-4 aminoacids) and aminoacids.

In the rest of the small intestines enzymes secreted by the cells that line the small intestine work. Oligopeptidases turn oligopeptides into aminoacids. Maltase turns maltose into 2 molecules of glucose. Sucrase turns sacrose into 1 molecule of glucose and one of fructose. Lactase turns lactose into 1 molecule of glucose and 1 of galactose. The intestinal lypase turns lipids into glycerol and fatty acids.
