Answer: The part of the enzyme where the substrate binds is called the active site (since that's where the catalytic “action” happens). ... Thanks to these amino acids, an enzyme's active site is uniquely suited to bind to a particular target—the enzyme's substrate or substrates—and help them undergo a chemical reaction. To catalyze a reaction, an enzyme will grab on (bind) to one or more reactant molecules. These molecules are the enzyme's substrates. In some reactions, one substrate is broken down into multiple products. ... The products then leave the active site of the enzyme.

What are the characteristics of flowering bulb?Bulb is a modified stem that is the resting stage of certain seed plants, particularly perennial monocotyledons. A bulb consists of a relatively large, usually globe-shaped, underground bud with membraneous.
Bulbs can be easily and effectively propagated using a variety of techniques, but always use disease-free material. Try lilies, snowdrops, daffodils, tulips and alliums.
Examples of true bulbs: onion, garlic, allium, daffodil, tulip, amaryllis, grape hyacinth, Dutch hyacinth, Dutch iris, scilla, lily.

neutrons.
B. Plutonium-240 breaks apart into xenon, zirconium, and three
neutrons.
C. Methane gas combines with oxygen to form carbon dioxide and
water.
O D. Two isotopes of hydrogen fuse to form helium.
SUBMIT
Answer:
C
Explanation:
Because its a chemical reaction or whatever but it's correct
A reaction where the atoms of elements are rearranged is when two isotopes of hydrogen fuse to form helium, which is option D. In this reaction, the atoms of elements (hydrogen isotopes) are rearranged.
The fusion process involves the combination of two hydrogen isotopes, typically deuterium and tritium, to form a helium nucleus. This nuclear fusion reaction is the primary process that powers stars, including our Sun, where hydrogen atoms combine to form helium, releasing a tremendous amount of energy in the process. Deuterium is an isotope of hydrogen that contains one proton and one neutron, while tritium is another isotope of hydrogen that contains one proton and two neutrons.

Name at least two ways in which insects are beneficial to humans.
Answer:
Natural and biological control :
The balance of nature depends on the activities of parasites and predators, the majority of which are species of insects. Researchers use this concept in biological control, and have been dramatically successful in many programs.
Silk :
The recognition of silk as a valuable product dates back to China, arguably in the year 2640 B.C. Presently, China annually produces some 30,000 tons of raw silk, which accounts for 80 percent of the world's supply. Most silk is produced from the cocoons of the Silkworm.

hardness
Explanation:
Mohs hardness, rough measure of the resistance of a smooth surface to scratching or abrasion, expressed in terms of a scale devised (1812) by the German mineralogist Friedrich Mohs. The Mohs hardness of a mineral is determined by observing whether its surface is scratched by a substance of known or defined hardness.

Answer:
So blood can reach the fetus
Explanation:
The blood can reach the fetus so that's why estrogen most likely need to increase blood flow in a pregnant woman's body
What is the function of estrogen?Estrogen refers to a group of hormones produced in the ovaries. The increase in estrogen during pregnancy enables the uterus and placenta to improve vascularization (the formation of blood vessels) transfer nutrients which support the developing baby.
In females, estrogen helps develop and maintain both the reproductive system and female characteristics, such as breasts and pubic hair.

ver a long period of time, flower shapes and color variation have changed as a direct response to attract more pollinators, such as bees and hummingbirds. This is an example of --
Predation
Competition
Parasitism
Commensalism
Answer:
This is an example of parasitism
Ver a long period of time, flower shapes and color variation have changed as a direct response to attract more pollinators, such as bees and hummingbirds. This is an example of Predation. Thus, option A is correct.
What are predators?A predator is a creature that eats all or a portion of the body of its victim, which may be alive or recently deceased. Predators are distinguished from decomposers, such as fungus and bacteria, which break down the remaining remnants of dead species, by the phrase "living or recently killed."
We can confidently classify a lion as a predator if we witness it devouring a zebra. However, the zebra is included in the wide definition as well! Prey for a predator can include both plants and fungi as well as living things.
Additionally, a predator is not required to kill its victim. Instead, it can just remove a part of the prey's body and leave it alive, like a grazing cow or a bloodsucking mosquito. Herbivory is the term for a predator-prey situation in which an animal or insect eats a plant; herbi- stands for plant, and -vory implies eating.
Therefore the correct option is B.

Natural selection involves energetic trade-offs between ________. Group of answer choices high survival rates of offspring and the cost of parental care increasing the number of individuals produced during each reproductive episode and a corresponding decrease in parental care producing large numbers of gametes when employing internal fertilization versus fewer numbers of gametes when employing external fertilization choosing how many offspring to produce over the course of a lifetime and how long to live Next
Answer:
The correct answer is ''high survival rates of offspring and the cost of parental care''
Explanation:
Natural selection is the differential reproduction of some genetic variants with respect to others. Natural selection favors individuals who maximize their total reproductive success throughout life, that is, it favors certain phenotypes or variants are associated with greater offspring and / or greater survival, that also means that selection will favor those who stop spending on a particular breed at the right time to invest in another, that is, the amount of energy invested in each of them. This same natural selection also favors those genes that make it effective when the body that carries them is in development to extract all possible parental investment from their parents.
