B Mutations increase the genetic variation within a population, and some of the variants may provide an advantage to individuals over time
C Mutations help stabilize the genetic variation within a population, and only one or two variants generally provide an advantage to individuals.
D Mutations help reduce the genetic variation within a population, and thus increasing the rate that new adaptations develop.
Answer:
B. Mutations increase the genetic variation within a population, and some of the variants may provide an advantage to individuals over time
The role of mutations in evolution by natural selection is option b. Mutations increase the genetic variation within a population.
Role of mutation in evolution:The mutation is significant as the first step of evolution since it developed the new DNA sequence for the specific gene that developed the new allele.
Also, at the same time, it rise the genetic variation within the population also it provides as an advantage to individual
hence, the option b is correct.

why does a deletion mutation usually cause more defects during protein synthesis than a point mutation?
Answer:
Deletion mutations can affect the entire base sequence.
Explanation:
Answer:
Deletion mutation may cause a shift of base sequence, causing the reading frames for base sequence to change during translation. This may affect the type of amino acid it the original base sequence codes for, resulting in a change in amino acid sequence in the polypeptide translated. Therefore, affecting the whole protein itself. There may be wrong amino acids that prevents vital bonds like disulfide bridges to form, resulting in a huge change in 3 dimensional conformation of the protein. A point mutation may result in a gene sequence being edited. However, only the target sequence is being mutated. The rest of the gene sequences are left untouched. Therefore, the impact is localised. This ensures that even though a few wrong amino acids may be in the polyleptide, most of the bonds that are crucial for the correct 3 dimensional conformation is still present, therefore, lesser defects will be resulted due to point mutation as compared to deletion mutation.

Warm-Up: What does it mean to be a prokaryotic cell? What
does it mean to be a Eukaryotic Cell? Which one came first?
(Think about the root words)
Answer:
eukrayotic cell l guess
Explanation:
A prokaryotic cell is a simple, single-celled (unicellular) organism that lacks a nucleus, or any other membrane-bound organelle. We will shortly come to see that this is significantly different in eukaryotes. Prokaryotic DNA is found in the central part of the cell: a darkened region called the nucleoid (Figure 1).
Unlike Archaea and eukaryotes, bacteria have a cell wall made of peptidoglycan, comprised of sugars and amino acids, and many have a polysaccharide capsule (Figure 1). The cell wall acts as an extra layer of protection, helps the cell maintain its shape, and prevents dehydration. The capsule enables the cell to attach to surfaces in its environment. Some prokaryotes have flagella, pili, or fimbriae. Flagella are used for locomotion, while most pili are used to exchange genetic material during a type of reproduction called conjugation.
Eukaryotic Cells
In nature, the relationship between form and function is apparent at all levels, including the level of the cell, and this will become clear as we explore eukaryotic cells. The principle “form follows function” is found in many contexts. It means that, in general, one can deduce the function of a structure by looking at its form, because the two are matched. For example, birds and fish have streamlined bodies that allow them to move quickly through the medium in which they live, be it air or water.
A eukaryotic cell is a cell that has a membrane-bound nucleus and other membrane-bound compartments or sacs, called organelles, which have specialized functions. The word eukaryotic means “true kernel” or “true nucleus,” alluding to the presence of the membrane-bound nucleus in these cells. The word “organelle” means “little organ,” and, as we learned earlier, organelles have specialized cellular functions, just as the organs of your body have specialized functions
Define the following types of sexual reproduction: Binary fission, budding. fragmentation, parthenogenesis
Answer:
Binary fission-Binary fission, asexual reproduction by a separation of the body into two new bodies. In the process of binary fission, an organism duplicates its genetic material, or deoxyribonucleic acid (DNA), and then divides into two parts (cytokinesis), with each new organism receiving one copy of DNA.
Budding-Budding is a type of asexual reproduction in which a new organism develops from an outgrowth or bud due to cell division at one particular site. The small bulb-like projection coming out from the yeast cell is called a bud.
Fragmentation-Fragmentation in multicellular organisms is a form of asexual reproduction in which an organism is split into fragments. Each of these fragments develop into matured organism, full grown individuals that are genetically and morphologically identical to their parents.
Parthenogenesis-
Parthenogenesis is a form of reproduction in which an egg can develop into an embryo without being fertilized by a sperm. Parthenogenesis is derived from the Greek words for “virgin birth,” and several insect species including aphids, bees, and ants are known to reproduce by parthenogenesis.

9. Explain why burning fossil fuels releases carbon dioxide.
10. Describe the path that carbon took to become a fossil fuel.
Answer:
4) The carbon dioxide comes from the animals and the oxygen comes from plants
7) Animals need to get their energy from other living things, but in order to do that said other living things need to have energy for the animals to get. Photosynthesis is the means by which plants and algae get their energy. Animals also need elemental oxygen,and photosynthesis produces this as a waste product as well
9) Fossil fuels consist mainly of carbon and hydrogen. When fossil fuels are combusted (burned), oxygen combines with carbon to form CO2 and with hydrogen to form water (H2O). These reactions release heat, which we use for energy

Compare how the nervous system and endocrine system work to send messages through the human body.
Answer:
Here is Your answer vote me as brainlist.
Explanation:
One of the most significant differences between the nervous system and endocrine system is that the nervous system uses electrical impulses to send messages through neurons while endocrine glands use hormones to send messages to the target cells through the bloodstream.
The nervous system uses electrical and chemical signals to quickly send messages through the body, while the endocrine system uses hormones to gradually send messages through the bloodstream.
What is nervous and endocrine system?The nervous system uses electrical and chemical signals to transmit information rapidly and directly to specific target cells. This system is composed of neurons, which transmit impulses through the body, and specialized cells called neuroglia, which support and protect the neurons. The nervous system is divided into two parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS includes the brain and spinal cord and the PNS includes the nerves that extend out to the rest of the body.
The endocrine system, on the other hand, uses hormones to transmit information more slowly and diffusely throughout the body. Hormones are chemical messengers that are secreted by glands and travel through the bloodstream to target cells. The endocrine system includes a variety of glands, such as the pituitary gland, thyroid gland, and adrenal gland, that produce hormones that regulate various physiological processes, such as growth, metabolism, and reproduction.

what are two organisms in the food web that have a predator-prey relationship? i need examples
Answer:
Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit. The words "predator" and "prey" are almost always used to mean only animals that eat animals, but the same concept also applies to plants: Bear and berry, rabbit and lettuce, grasshopper and leaf.
Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit.
What do you mean by predator-prey relationship?In the predator prey relationship, one species is feeding on the other species. The prey species is the animal being fed on, and the predator is the animal being fed. The predator prey relationship develops over time as many generations of each species interact.
Predator and prey populations cycle through time, as predators decrease numbers of prey. Lack of food resources in turn decrease predator abundance, and the lack of predation pressure allows prey populations to rebound.
The relationships between predators and prey play an important role in structuring ecological communities, with predators influencing the dynamics of their prey in ways that cascade through ecosystems.

Fermentation is a chemical process by which molecules such as glucose are broken down anaerobically. Therefore, option (A) is correct.
What do you mean by fermentation?Fermentation is a metabolic process that produces chemical changes in organic substrates through the action of enzymes. In biochemistry, it is narrowly defined as the extraction of energy from carbohydrates in the absence of oxygen.
Moreover, fermentation occurs in the absence of oxygen (anaerobic conditions), and in the presence of beneficial microorganisms (yeasts, molds, and bacteria) that obtain their energy through fermentation.
Hence, fermentation reactions occur in the cytoplasm of both prokaryotic and eukaryotic cells. In the absence of oxygen, pyruvate does not enter the mitochondria in eukaryotic cells.
