How does cellular respiration provide energy for life processes?
During cellular respiration animal cells combine oxygen with food molecules to release energy to live and function. Remember that cellular respiration produces carbon dioxide as a waste product. Animals use energy to grow, reproduce, and to function. They release the carbon dioxide into the air as a waste product.

Why the Chimpanzee's diploid number is 24 instead of 48.
I am not sure if the following table supposes me to write 2 (N) on here...
Thank you very much
Answer:
It has 24 pairs and 48 number of chromosomes.
Explanation:
The Chimpanzee's diploid number of chromosome is 24 pairs instead of 48 because of the resemblance with the human cell that have 23 pairs of chromosome. The Chimpanzee has 24 pairs of chromosome or another words we can say that chimpanzee has 48 number of chromosomes not pairs. Humans have 23 pairs whereas apes have 24 pairs of chromosome. The theory suggested about this close number of chromosomes is that at some point two ape chromosomes fused to make a single human one.

Changes in ____ result in a change in protein structure which alters the ____-type of the organism and MIGHT increase _____.
Answer:
DNA, genotype and resistance.
Explanation:
Change in DNA of an organism results in a change in the shape and structure of protein because DNA has the codes of instructions on the basis of which ribosomes synthesis proteins for the cell. This change occurs due to mutation in the DNA sequence that causes change in protein. Due to this mutation, the genotype of an organism changes and might increases its resistance that leads to its survival in that environment so we can say that mutation has good effects on the organisms.
what kind of cells have haploid chromosomes?
Answer:
Haploid describes a cell that contains a single set of chromosomes. The term haploid can also refer to the number of chromosomes in egg or sperm cells, which are also called gametes. In humans, gametes are haploid cells that contain 23 chromosomes, each of which a one of a chromosome pair that exists in diplod cells.

which type of feature of Earth's crust does the diagram show (A) reverse fault (B) anticline (C) normal fault (D) syncline
its enviromental science
The figure illustrates the anticline of the earth's crust.
The correct option is B.
Anticline definition:A structural trap called an anticline is created when rock layers are folded into the shape of an arch. In an anticlinal trap, the rock layers were initially horizontally stacked until earth movement caused them to fold into such an arch-like structure known as an anticline.
What distinguishes an anticline?Rock formations called anticlines are folded structures with upward convex shapes. This means either anticline resemble a lowercase "n" or an uppercase "A" (remembering the shape of an anticline is as simple as saying "A is for Anticline"). They originate from horizontal and rather flat rock layers.
What is the crust of Earth?The outermost layer of a terrestrial planet is referred to as its "crust." The older, heavier continental crust and the denser, younger oceanic crust make up the majority of the Earth's crust. Plate tectonics provides information about the dynamic geology of the Earth's crust.

Natural selection is sometimes described as "survival of the fittest." Four friends were arguing about what the phrase "survival of the fittest" means. This is what they said: Diya: "I think ‘fit' means bigger and stronger." Ayush: "I think ‘fit' means more likely to reproduce." Daniel: "I think ‘fit' means being able to run faster." Hari: "I think ‘fit' means more intelligent."
Answer:
Ayush is correct.
Ayush: "I think ‘fit' means more likely to reproduce
Explanation:
Survival of the fittest simply means when organisms living in an environment develop traits or characteristics that help them to fully adapt to the environmental conditions and are able to survive, reproduce and pass on traits to their next generations. It's an indication that the organisms posses some characteristics that can help them to survive and reproduce in unfavorable environmental conditions.

Which two compounds are always together?
a. Oxygen and Water
b. Carbon Dioxide and Glucose
C. Oxygen and Glucose
d. Carbon Dioxide and Solar
Answer:
a. Oxygen and Water
Explanation:
Oxygen and water are a pair and they come together. This is proven by the equation for water which is H2O which contains oxygen.
Oxygen and water compounds are always together. So, the correct option is A.
What are Compounds?A compound is a substance made up of two or more components which are chemically combined in a certain ratio. Chemical bonds hold the elements in a compound together. These bonds can be covalent, ionic, or metallic, according to the characteristics of the elements involved.
Because oxygen is a fundamental component of molecules of water, which have a chemical formula H2O, oxygen and water are frequently found together in nature. Water is required for life as well as many biochemical activities, while oxygen is required for respiration in many species. As a result, oxygen and water are frequently found combined in natural habitats.
Therefore, the correct option is A.

How are ferns, gymnosperms, and angiosperms alike? They are all vascular plants. They depend on water for fertilization. They all produce seeds. Reproduction depends on birds, bees, and other animals.
Answer:
The correct answer is ''They are all vascular plants''.
Explanation:
Vascular plants or tracheophytes are those organisms of a more evolved plant nature, they are those that have leaves, stem and roots and that have a vascular system formed by conducting vessels. Ferns are pteridophytic vascular plants, they do not produce flowers or seeds and are mostly herbaceous. All those vascular plants that have seeds but do not have flowers are called gymnosperms. The seeds are not covered or protected by an ovary, so they appear visible on the leaves or other parts of the plant. Angiosperms are plants with flowers, whose seeds develop within the ovary, which grows and becomes fruit.

they all vascular plants

List 5 uses for proteins in the cell.
Answer:
Protein has many roles in your body. It helps repair and build your body’s tissues, allows metabolic reactions to take place and coordinates bodily functions. In addition to providing your body with a structural framework, proteins also maintain proper pH and fluid balance. Finally, they keep your immune system strong, transport and store nutrients and can act as an energy source, if needed.

Proteins help in cell structure formation, and cell transport, allow biochemical reactions, cell repair and also help in cell division.
What are cellular proteins?Proteins present in the cell are of various kinds. They are formed in the cell by the process of DNA transcription and translation.
The proteins formed in the cell then go on to perform various functions. The cellular proteins form the structure of the cell. They do that either by forming the cell membrane or the membrane of the organelles.
The cellular proteins also help in transport of nutrients. This transport is of two types. It can transport materials from inside to outside of the cell and vice versa. It can also transport materials inside the cell to other organelles.
Various biochemical reactions in the cell are possible because of the cellular proteins. The proteins formed in the cell are also used for cell repair and cell division.
Therefore, the various functions performed by the cellular proteins are cell structure formation, cell transport, allowing biochemical reactions, cell repair and help in cell division.
