Which describes the role of
oxygen in photosynthesis?
• It is a reactant, so it is released by the plant.
O It is a
product, so it is released by the plant.
• It is a reactant, so it enters the plant.
• It is a product, so it enters the plant.

Answer: The correct option is (the region of an enzyme that attaches to a substrate).

Explanation:

The anabolic and catabolic processes in a cell are directed and regulated by enzymes. An enzyme has the ability to speed up a metabolic reaction by lowering the amount of energy needed to start the reaction. Without enzymes, these processes would be extremely slow. They also arrange the reacting molecules in a manner that will cause the chemical change to take place rapidly. It does so through the following steps:

--> molecules of substrate combine with the enzyme at its active site.

--> the substrate molecules combine with enzyme molecules for a short time, forming an enzyme-substrate complex.

--> New substance ( product) is formed which leaves the active site of the enzyme thereby making it free for another reaction to take place.

In conclusion, the ACTIVE SITE of an enzyme is the region of an enzyme that attaches to a substrate allowing chemical reaction to take place.

Answer:

Signal transmission paths Learn how signals are transmitted within a cell from the cell membrane receptor. The chains of molecules that pass intracellular signals are known as intracellular signal transduction pathways.

Signal transduction pathways that include a phosphorylation cascade cause a structural change in each phosphorylated protein, with the addition of a phosphate group to activate the protein. Thus, the correct option for this question is D.

The Phosphorylation cascade may be characterized as a series of signaling pathways that significantly involve the activation of one enzyme through the effect of other in order to accomplish the downstream signaling pathway.

According to the context of this question, the process of phosphorylation involves the addition of a phosphate group over the compound in order to stimulate its activity. This is accomplished by the structural change in each phosphorylated protein, with the addition of a phosphate group to activate the protein.

Therefore, the correct option for this question is D.

The cells in the prey that are most likely influenced by the poison present in the darts exist the muscle cells.

A muscle cell exists also known as a myocyte when directed to either a cardiac muscle cell or a smooth muscle cell as these exist both small cells. A skeletal muscle cell exists long and threadlike with many nuclei and is named a muscle fiber. Muscle cells originate from embryonic precursor cells named myoblasts.

The muscle cells exist as a specialized kind of cell (one of the four tissues) that can contract to exert action.

These cells (muscle cells) can be paralyzed by utilizing various inhibitors of movement such as poisons.

In conclusion, the cells in the prey that exist most likely affected by the poison present in the darts exist the muscle cells.

There are 4 phenotypes are possible from the 3 alleles coding for human blood. The correct option is B.

The set of qualities or characteristics that can be observed in an organism are known as its phenotype in genetics.

The word includes an organism's anatomy, developmental processes, physiological and biochemical characteristics, behaviour, and the outcomes of behaviour.

The genotype of an individual is their own DNA pattern. More specifically, the two alleles a person acquired for a particular gene are referred to by this phrase.

The clinical presentation of a patient is the observable expression of this genotype, or phenotype.

A, B, AB, and O are the four phenotypes of blood that can occur. The gene that determines blood type has three alleles. Six distinct genotypes are possible because there are three different alleles.

Thus, the correct option is B.

Answer:

IS THIS EVEN ENGLISH YES

Explanation:

The statement is False, it should read, Most features are caused by inheritance of a character. Thus option A is correct.

Inheritance is defined as the transfer of genetic information from parents to their offspring.

The transferred characters or traits include eye color, hair color, and blood type.

Trait can be defined as the genetic character which can be transmitted by the parent to its offspring during fertilization.

The trait which is expressed phenotypically is called as dominant trait while the other trait which is not expressed called as recessive trait.

These variations are observed in the species due to survival benefits or genetic drift.

Acquired traits are acquired by an individual in his lifetime which is due to their own activities or external influence.

Like inherited traits, acquired traits are unable tp pass to the next generation like ability to dance, cook.

Thus option A is correct.

Answer:

The angiosperms, or flowering plants, are the largest and most species-rich phylum of plants, with more than 250,000 species estimated.

Defining Characteristics

The term "angiosperm" derives from two Greek words: angeion, meaning "vessel," and sperma, meaning "seed." The angiosperms are those plants whose seeds develop within a surrounding layer of plant tissue, called the carpel, with seeds attached around the margins. This arrangement is easily seen by slicing into a tomato, for example. Collectively, carpels together with the style and stigma are termed the ovary, and these plus associated structures develop into the mature

Answer:

centimeter

Explanation:

Description:

All answer choices are units that are used to measure length so the first hint isn't much help.  

The only unit listed that is smaller than a meter is a centimeter so the answer would be centimeter.

1 Centimeter = 0.01 Meter

( If it helps to remember centi means one hundredth, so centimeter means one hundredth of a meter )

centimeter is the lowest standard unit of measure the length.

The product of speed and time can be represented as distance.

d=s×t, where d is the distance m, t is the time taken to cover s

s is the speed in m.s-1

Different units can be used to measure Length like centimeters, inches, meters, it can be classified into two types such as Standard units of measuring length and non-standard units of measuring length.

Standard Units of Measuring Length include the pre-defined  such as If two measure the length of the same object using any standard unit will get the same result.

standard units of length are measured in the form of meters, centimeters, inches, feet. It can be up two types such as Imperial units and metric system units.

Imperial System is based on existing units, examples are nautical mile,  mile, rod, inch etc.

Metric units are kilometer, hectometer, decameter, meter, centimeter, and millimeter etc.

First, there is a need to understand what the carrying capacity is as it relates to the environment:

Now let us look at the graph. The population size grew from 0 and then leveled off at 2,000 with time. The leveling-off also happened without any oscillation, meaning that the maximum population size the environment can support is 2,000.

Hence, the portion on the graph that indicates the carrying capacity would be the plot where the population size is 2,000 and the time being between 12 and 18. This has been circled and labeled as 'K' in the attached image.
