In asexual reproduction, genetic information comes from only one parent; whereas, in sexual reproduction, genetic information from two parents to form an offspring.
What is asexual reproduction?Asexual reproduction is a type of mechanism by which only one parental organism may produce offspring and therefore it is not associated with the formation of gametes.
In sexual reproduction, the cells from different parents having half genetic material fuse to produce an egg that will develop into an adult organism by a process known as fertilization.
The different types of asexual reproduction in organisms include, among others, vegetative propagation, binary fission (bacteria), Budding, fragmentation division, reproduction by spores (sporogenesis), etc.
In conclusion, in asexual reproduction, genetic information comes from only one parent; whereas, in sexual reproduction, genetic information from two parents to form an offspring.

What type of stain is a gram stain?
a. simple
b. differential
c. negative
d. specific
Gram stain is a type of differential stain.
Differential staining is a type of staining that is used to distinguish different types of microorganisms by differentiating their characteristics or composition. Therefore, gram stain is considered a type of differential staining since it uses two types of stains to distinguish gram-positive organisms from gram-negative organisms. These stains are crystal violet and safranin stains.
In contrast to differential staining, simple staining is used just to study the features of a particular bacteria and cannot be used for distinguishing purposes.
Negative staining also cannot be used for differentiating purposes as it can just be used to analyze the morphological features of cells that cannot be stained easily.
Another factor that differentiates gram stain from other staining techniques is that it uses two stains while other techniques only use one type of stain.

OA. fact.
B. law.
OC. theory.
OD. hypothesis.
Law is based on the fact (here, gravitational pull) and shows the relation between the moon and the earth (tides). Thus, option B is correct.
What are tides?
Tides are the waves observed in seas. It is mainly due to the gravitational pull exerted by the moon on the earth. The tidal force so generated is responsible for high tide and low tide.
Tides, high or low can be predicted timely. Usually there are two high tides and two low tides observed in a day. However, during the full moon and new moon, the earth, moon and the sun align in orientation, creating a combined gravity.
This is responsible for 'spring tides' which can be considered even more higher or lower in amplitude.

speciation occurs when: any two mutations become fixed differences between two populations. two populations become physically separated from each other. partial reproductive isolation between two populations is achieved. two populations become reproductively isolated from one another. all deleterious mutations have been eliminated from two populations.
Speciation occurs when two populations become reproductively isolated from one another.
In the middle of the 20th century, Ernst Mayr gave the biological concept of species.
According to the biological concept of species, a species is defined as a group of individuals who can interbreed to produce fertile offspring.
Two groups of individuals are considered different species if they cannot interbreed to produce fertile offsprings i.e, they are reproductively isolated from one another
Generally, speciation occurs due to mutations.
Mutations are large differences that arise suddenly in a population.
These mutations keep on accumulating and due to this reason, a group of individuals become different from their species and lead to the creation of a new, different species.
Hence, speciation occurs when two populations become reproductively isolated from one another.\

Proteins provide the primary function of enzymes, which are catalysts that quicken practically all chemical events within cells. Although some biological reactions can be catalyzed by RNAs, proteins are responsible for the majority of them. A biological catalyst called an enzyme is usually always a protein. It accelerates a certain chemical reaction in the cell.
An enzyme will cling to (bind) one or more reactant molecules in order to catalyze a process. The substrates of the enzyme are these substances. Proteins called enzymes are made up of amino acids connected by one or more polypeptide chains. The fundamental structure of a polypeptide chain refers to this arrangement of amino acids.

Within each year, what is the pattern of change in CO₂ concentration? Why does this pattern occur?
The pattern of change in CO₂ concentration is new plant growth in the spring increases photosynthesis rates, which lowers CO2 concentrations; this decline continues until autumn, when leaves fall and decompose, raising CO2 concentrations.
The level of carbon dioxide within the surroundings rises and falls every 12 months as plant life, thru photosynthesis and respiration, absorbs the gas in the spring and summer season, and launches it in fall and wintry weather. Now the range of that cycle is expanding as extra carbon dioxide is emitted from burning fossil fuels and different human activities.
In spring, flora in the Northern Hemisphere starts to develop and absorb CO2 from the atmosphere, so atmospheric CO2 attention decreases as the road dives down. In fall, flora starts to decay and release their CO2 again into the ecosystem, so atmospheric CO2 attention increases the line shoots up. plants are accumulating carbon within the spring and summer while they are lively, and they're liberating carbon again to the air in the fall and winter.

Explanation:
Thinking about our nutritional needs and feeding behavior, propose an evolutionary explanation for why amylase, unlike other digestive enzymes, is secreted into the mouth.
Salivary glands secrete amylase, which causes starch to break down into maltose in the mouth. As a result, the adaptation to find food sources that provide rapid energy is salivary amylase secretion.
Three pairs of salivary glands are the parotid, submaxillary, and sublingual. Saliva is a viscous fluid that is produced by salivary glands. Saliva contains two enzymes called salivary amylase and lysozyme.Salivary amylase detects maltose by dissolving starch. As a result, the mouth is where carbohydrate digestion starts. The antimicrobial and antibacterial characteristics of lysozyme.Starch-containing food molecules have long been important parts of the human diet. The amylase enzyme (AMY) genes are heavily selected in every generation due to the high sugar content of the human diet.The pancreas and salivary glands both express these genes. Since sugar molecules supply more immediate energy than protein and fat, the presence of amylase in the saliva facilitates the quickest possible digestion of these molecules. The use of foods high in starch has led to the development of the adaption.Learn more about the Human digestive system with the help of the given link:

The correct option is (b) natural selection favors altruistic acts when the resulting benefit to the recipient, corrected for relatedness, exceeds the cost to the altruist.
Kin selection is the reproductive success of an organism's colony as a result of the individual organism's altruistic conduct. The term "inclusive fitness" is used. An organism sacrifices its life to ensure the survival of its colony in this sort of natural selection. Altruistic conduct is favored by natural selection in organisms, which is advantageous for the entire colony.At the group level, altruistic behavior is favorable. Any population that has evolved toward altruism is willing to sacrifice itself for the good of the whole. Altruistic behavior might develop as a result of the group's improved relative fitness.Altruism is therefore favored by natural selection for the benefit of the group even though it can cost the individual their life.

The phylogenetic tree expresses the relationship between different taxa and how different homolog groups evolved. The correct option is c). the homolog has evolved more rapidly in mice.
What is a phylogenetic tree?
Phylogenetic trees are graphic representations that express the evolutive process through which several groups -taxa- emerged through history.
The phylogenetic tree is composed of
Root ⇒ It represents the oldest common ancestorNodes ⇒ Divergence point in which single taxa differentiate or diverge. These nodes are the most recent common ancestor of the new diverging groups.Branches ⇒ The extremes of branches represent taxonomic groups or lineages.All the taxa in the tree share a far common ancestor. New traits emerge through history that drives the evolution of new lineages. These traits might be either morphological or molecular.
Two taxonomic groups are more related if they have a recent common ancestor. There are fewer differences (morphological or molecular) between these two groups.
On the other hand, two lineages will be less related if their common ancestor is not a recent one and is located far away in the tree. Several differences exist between these groups because many changes occurred in the middle.
Two groups are homologous when they have a common recent ancestor, even when one of the groups evolved into new groups later in time.
In the exposed example, the frog is homologous to the group composed of chicken, human, and mouse. They share a common ancestor.
