Answer:
This question is incomplete
Explanation:
This question is incomplete. However, it should be noted that the idea of blocking the drainage, which could cause waterlogging (since the water will not be able to leave the field), is a type of irrigation that ensures there is sufficient amount of water for the plants to grow during a growing season. Although, some plants do not grow well in environments like this (in the case of waterlogging) because this environment lowers oxygen level in the root o the plant (caused by the water at the top of the soil).
4. When an offspring grows off from the body of a parent organism it is called __________________. *
a.fission
b.budding
c.fragmentation
d.sporulatioin
Answer:
Budding
Explanation:
It is asexual reproduction in which offspring grows out of the parents organisms.
In the process of budding, an offspring grows off from the body of a parent organism and buds off when fully matured. Thus, the correct option is B.
What is Asexual Reproduction?
Asexual reproduction is the type of reproduction only a single parent is involved. In this process, offspring are developed from a single parent called mother cell and these offspring are genetically identical to the parent hence are also called as clones.
During the process of budding which is a types of asexual reproduction, a new organism develops from an outgrowth or bud which is formed on the parent plant due to the cell division at a particular site on the parent plant. For example, the small bulb-like projections coming out from the yeast cell are the buds which give rise to new yeast organism.
Therefore, the correct option is B.

feel things around you
Explanation:
Motor neurons
Motor neurons play a role in movement, including voluntary and involuntary movements. These neurons allow the brain and spinal cord to communicate with muscles, organs, and glands all over the body.
Interneurons
Interneurons are neural intermediaries found in your brain and spinal cord. They’re the most common type of neuron. They pass signals from sensory neurons and other interneurons to motor neurons and other interneurons. Often, they form complex circuits that help you to react to external stimuli.

Answer:
4. According to what is observed in the diagram, the maltose (substrate) binds to the maltase (enzyme) to obtain glucose molecules (product), in a process of hydrolysis of the maltose.
5. Three factors that can affect intestinal maltose activity - slowing it down or stopping it - are temperature, pH and substrate depletion.
Explanation:
4. Enzymes, such as maltase, have the function of making a reaction faster and decreasing the activation energy. Maltase is responsible for breaking down a maltose molecule, a dimer, into two glucose monomers, which is a hydrolysis reaction of the bonds that hold glucose molecules together.
5. There are several factors that can cause the decrease or cessation of the activity of an enzyme. Enzymes are activated when substrate is available and work best under ideal temperature and pH conditions. When there are alterations of these factors, the enzyme will reduce or stop the reaction in which it intervenes.
pH: when the pH increases or decreases it produces a decrease in the speed of reaction that catalyzes an enzyme. Very high or low pH levels can denature the enzyme and make the expected reaction not occur. Temperature: like pH, changes in temperature can slow or stop maltase activity. Substrate availability: It is a fact that when the specific substrate of an enzyme becomes depleted, the rate of reaction slows down, stopping when no substrate is available.What structure would not be found in a cell from human skin

Explain how photosynthesis and cellular respiration work together.
Answer:
photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

Which types of mutations in the lac operon stop Escherichia coli from utilizing lactose as a carbon source? a) promoter deletion b) lactose-binding site mutation c) repressor DNA-binding site mutation d) operator deletion
Answer:
D.) repressor DNA-binding site mutation
Explanation:
lacl prevents the repressor polypeptide is a mutant that prevent operon from binding lactose, and thus will bind to the operator and be non-inducible.. This mutant will represses the lac operon whether lactose is present or not and the lac operon will not be expressed. It is also called“super-supperesor".
The lacI locus – One type of mutant allele of lacI (callled I-) prevents the production of a repressor polypeptide or produces a polypeptide that will not allow to bind to the operator sequence.
This is also a constitutive expresser of the lac operon because absence of repressor binding permits transcription.
T/F Osmosis and diffusion are both examples of passive transport.
A.True
B.False
Both osmosis and diffusion are passive transport processes, meaning that no additional energy is needed for them to take place. In both diffusion and osmosis, particles move from an area of higher concentration to one of lower concentration.
The given statement "Osmosis and diffusion are both examples of passive transport" is True.
Passive membrane transfer methods are the most direct. Passive transport is a phenomena that happens spontaneously and doesn't require the cell to use energy to move. Diffusion is the process by which chemicals travel passively from a region of higher concentration to a region of lower concentration. A concentration gradient is a difference in the concentration of one substance throughout a physical region.Transport that is done passively is called diffusion. Until the concentration is the same across the space, a single substance has a tendency to travel from an area of high concentration to an area of low concentration.Based on the gradient of water concentration across the membrane, osmosis is the mechanism by which water diffuses through a semipermeable membrane. Osmosis moves just water across a membrane, and the barrier restricts the diffusion of solutes in the water, whereas diffusion distributes material across membranes and into cells.Learn more about the passive transport with the help of the given link:

Orms of obvious, overt prejudice, which are considered inappropriate by most social standards today, are sometimes called:________.
Answer:
Discrimination
Explanation:
Discrimination of prejudice refers to the act of treating a person or people in a way that is wrong, unlawful, and inconsistent with the generally accepted moral standards just because they are different especially with respect to age, nationality, gender, etc
There are two categories of discrimination:
Overt and Covert.Discrimination or prejudice is over when those who practice it are unafraid to make their thoughts and actions public. Many times this is so because the society in which they live condones such behavior and because there are no repercussions, they bold to make their unjust acts public. For example, name-calling, intentional rejection of job applications, etc.
Covert refers to using the system or giving logical reasons for discriminatory behavior. This is more subtle. For example, an employer may say they are not taking females due to the prerequisites of the job. Refusing "nicely" to be treated by a person of color in a hospital is another example.
Covert aggression of prejudice is often masked and occurs where the laws are relatively stiff on those who practice them. Also, a society that is evolving from largely prejudicial to less discriminatory will see more covert forms that overt forms of discrimination because those who practice overt prejudice are bold because they know that there are many more who think like them.

Why dont solar eclipses happen every time the moon is in between the sun and the Earth?
Answer:
because the moon doesn't line up exactly between the sun and the earth every time it passes.
Explanation:
A solar eclipse can only occur when the Moon is close enough to the ecliptic plane during a new moon. ... Total solar eclipses are rare at any particular location because totality exists only along a narrow path on the Earth's surface traced by the Moon's full shadow or umbra. An eclipse is a natural phenomenon.

What methods would the body use to provide a
person with energy throughout a race?
DONE
C
Intro
Answer:
The methods the body would use to provide a person with energy throughout a race is using the ATP in the muscle cells for the first 3 seconds.
For the next 8 to 10 seconds, the body replaces the used ATP and produces more.
Within the next 90 seconds of the race, anaerobic respiration is used up to make more ATP (Adenosine triphosphate).
Therefore, during the whole process, the three energy systems used are:
the ATP-PC System
the Glycolytic system
the Oxidative system

Which categories of amino acid would you expect to find on the surface of a soluble protein, and which would you expect to find in the interior? What distribution of amino acids would you expect to find in a protein embedded in a lipid bilayer?
Answer:
Polar and charged amino acid residues (the remainder after peptide bond formation) are more likely to be found on the surface of soluble proteins where they can interact with water, and nonpolar (e.g., amino acid side chains) are more likely to be found in the interior where they are sequestered from water.
Explanation:
The amino acids with POLAR and CHARGED side chains are expected to be observed on the membrane surface, whereas amino acids with NON-POLAR and HYDROPHOBIC side chains are expected to be found inside the lipid bilayer.
The lipidic bilayer is mainly composed of phospholipids.Phospholipids have hydrophilic, polar phosphate heads facing out on each surface to interact with water and hydrophobic fatty acid tails facing each other inside the lipid bilayer.The polar and charged side chains of amino acids are expected to be observed on the surface of membrane proteins because they can interact with water (H2O) molecules.On the other hand, nonpolar side chains of specific amino acids are expected to be observed inside the lipid bilayer to interact with the hydrophobic fatty acid tails of phospholipids.The polar amino acids include glutamine, glutamic acid, arginine, asparagine, aspartic acid, histidine, lysine, serine, and threonine.Moreover, amino acids with hydrophobic side chains include leucine, isoleucine, glycine, alanine, valine and proline.In conclusion, amino acid residues with POLAR and CHARGED side chains are expected to be observed on the membrane surface, whereas amino acids with NON-POLAR and HYDROPHOBIC chains are expected to be found inside the lipid bilayer.

Explanation:
1. Compare and contrast mitosis and meiosis. 2. What major event occurs during interphase?
Answer:
1.
contrast between mitosis and meiosis
Mitosis
- it takes place in somatic cells in multi cellular organisms in order to provide growth, however, in unicellular organisms it is reproductive division as well. is the means of reproduction in single-celled organisms. Other organisms use it for the growth of tissues (somatic cells)
- exact number of chromosome in offspring
- no recombination or crossing over
- no pairing found
- major phase: prophase, metaphase, anaphase, telophase
Meiosis
- takes place in sex cells to form gamete formation during sexual reproduction
- half of the chromosome number found in gametes of the parents thus, known as reduction division
- due to crossing over takes place recombination found.
The pairing of chromosomes takes place
- major steps:
Meiosis 1 – prophase, Metaphase, anaphase, Telophase, and
Meiosis 2: Prophase, Metaphase, Anaphase, and Telophase
2. Interphase takes place prior to both mitosis and meiosis which is divided into 3 sub phases-G1, S and G2 phases.
The major events are as follows:
G1- RNA and protein synthesis takes place and cell grows in size
S- DNA replication takes place, Centriole duplication occurs and synthesis of histone proteins.
G2- RNA and Protein synthesis continues.
