A substrate enters the active site of enzyme.The enzyme and the substrate bind to form the enzyme substrate complex.The chemical reaction occurs.New substance called product is formed.What is enzyme substrate complex?
When an enzyme binds to its substrate, an enzyme-substrate complex is formed. The activation energy of the reaction is reduced, and the reaction proceeds more rapidly thanks to the complex's provision of certain ions or chemical groups that actually form covalent bonds with molecules at a vital point of the reaction process.

When do land breezes develop? Which way does wind move during a land breeze?
Answer:
A low-pressure zone forms above the land surface from the rapid loss of heat. A high-pressure zone forms as the cooler land cools the air immediately above the surface. Winds aloft flow from the ocean to the land. Winds at the surface flow from high to low pressure, creating a land breeze

Refer to the diagram provided. This cell can conduct cellular respiration. Name a product of cellular respiration that is used as a reactant in photosynthesis?
CO2
ATP
Glucose
02
Answer: CO2
Explanation: A product of cellular respiration is Carbon Dioxide. Carbon dioxide is also needed for plants to go through photosynthesis. Therefore, that would be the product to cellular respiration and the reactant in photosynthesis.
A. CO₂
Cellular respiration is the process by which organisms use oxygen to break down food molecules to get chemical energy for cell functions. The energy released is captured in molecules of adenosine triphosphate, or ATP, which then supply it to fuel other cellular processes.The process begins in the cytoplasm and is completed in a mitochondrion. Cellular respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport.Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water.
Therefore, option A is correct.

The ability of the carboxyl and amino groups to adopt a charge in biology makes
them very important functional groups in proteins. Use the image to choose the
correct statement below?
O Negatively charged regions of molecules tend to have carboxyl groups.
O Positively charged regions in molecules tend to have long carbon chains.
O Only one region of molecule can carry a positive charge at once.
The correct statement regarding the structure in the above image is as follows: negatively charged regions of molecules tend to have carboxyl groups (option A).
What are amino acids?Amino acids are the monomeric components of proteins. They are any organic compound containing both an amino and a carboxylic acid functional group.
The amino group has a formula -NH₂ while the carboxyl group has a formula -COOH.
According to this question, the ability of the carboxyl and amino groups to adopt a charge in biology makes them very important functional groups in proteins.
As observed in the image of the amino acids, only the carboxyl group carries a negative charge (-), hence, it is correct that negatively charged regions of molecules tend to have carboxyl groups.

What statistical measure is used to measure narrow-sense heritability by comparing parents to their offspring
For assessing the almost full additive genetic variation while potentially avoiding biases that can occur when modeling close relatives is possible by correlating phenotypic similarity to degree of IBD sharing among conventionally unrelated people.
What is heritability?Heritability is an important genetics parameter is heritability. Traditional estimates based on family or twin research may be inaccurate because of genetic variance that is not additive or shared environmental factors.
The narrow-sense heritability supplied by uncommon or otherwise poorly labeled causative variations is often underestimated by those based on genotyped or imputed variants, on the other hand.
All variations across chromosome pairs are shared by identical-by-descent (IBD) portions of the genome, with the exception of fresh mutations that have developed since the last common ancestor.
Using phenotypic simulation with thousands of people to use an IBD-based technique (GREML-IBD) to evaluate heritability in unrelated individuals.

The correct answer is - Sclerenchyma
Explanation:
Sclerenchyma are the dead cells with narrow lumen lignified cells. These dead cells has numerous pits that helps in trading the various substances to neighboring cells. At matuarity, hese cell lack the protoplast so therefore called dead cells .
Sclerenchyma cells are lignified which makes them thick and these cells help in the supporting the plants. These cells are impereable to almost everything gases, substances and many more.

Considering the drifting of continents, how do you explain the abundance of marsupials and the absence of native placental mammals in Australia
Answer:
this phenomenon is a natural consequence of evolutionary processes and continental drift
Explanation:
Marsupials are mammals in which newborn offspring are carried in a pouch of the female (mother) body. On the other hand, placentals are mammals that complete embryo development in the mother's body, in the placenta. All the extant marsupials are endemic to Australia and the Americas. It has been shown that marsupials diverged (evolved) in South America, Australia and Antarctica when these landmasses were joined. In Australia, marsupials evolved to fit an ecological niche, which can be attributed to geographic isolation due to continental drift, while placental mammals are relatively recent and more scarce (mainly bats and rodents) within this region.
