How do changes in wind currents affect the short-term climate in a region?
88
O Prevailing winds can cause a milder climate with heavy rain.
Global winds can cause a longer summer.
O Prevailing winds can cause heavy rains or a dry climate.
O Global winds can cause a longer winter.
The changes in wind currents affect the short-term climate in a region occurs prevailing winds can cause heavy rains or a dry climate.
Why is the climate changing?Climate change can be caused by natural processes on the Earth itself or by external forces, including variations in the intensity of sunlight, or even more recently, by human action.
The changes in the sea currents which affect the waters and the climate of the region. Thus the answer is prevailing currents created large rain. These events lead to the creation of the changes that lead to the formation of the weather changes.

How do the chromosomes of an offspring cell compare with the chromosomes of the parent cells?
Answer:
Offspring will usually have half the amount of chromosomes from each parent. For example: Mother Human= 46 Chrom, Father Human= 46 Chrom, Baby Human= 23 Chrom from father and 23 Chrom from mother.
There are just half as many chromosomes. Typically, children inherit half of each parent's chromosomes.
What are chromosomes?As an illustration, the mother and father of a human have 46 chromosomes each, and the baby has 23 chromosomes from each parent.
The sister chromatids reach their opposing poles at this final stage of mitosis. The cell's tiny nuclear vesicles start to reform around the chromosome cluster at each pole. As the process by which the parent cell transfers its DNA to its two daughter cells, mitosis is a crucial component of cell division.
Homologous chromosomes align in pairs during meiosis. Chromosomes are independent of one another during mitosis.
Therefore, half as many chromosomes the chromosomes of an offspring cell compare with the chromosomes of the parent cells.

Explain two ways materials can enter the cell through passive transport. Include in your answer: the types of substance that is transported, the concentration gradient, and any structures in the cell membrane required to be used.
Answer:
Osmosis and facilitated diffusion are two forms of passive transport that are integral to cellular transport mechanisms.
Explanation:
Cells surrounded by a bilipid layer or plasma membrane are amphiphilic, with their polar, hydrophilic lipid heads facing outward, while their hydrophobic non-polar lipid tails facing each other inward.
Although lipid-soluble molecules travel quickly through the bilayer, traveling across its surface into the cell is often difficult for charged and large molecules. Thus, transport proteins, pores and gated channels, transmembrane channels, embedded within the membrane, help to preserve selective permeability.
Across plasma membranes as a form of passive transport in cells, substances move via:
osmosis - water molecules readily pass through the membrane; the molecules move from high concentration regions to low concentration regions at will through the membrane- they move down their concentration gradientfacilitated diffusion - channel proteins allow charged ions to move across the membrane. Sodium ions are able to pass freely through specialized sodium channel pores into some cells. These channels always remain open- the ions move down their concentration gradient.

An RNA sequence includes 12 nitrogenous bases, AUGGUGCAUGUC. What is the maximum number of amino acids for which this sequence could code?
A). 4
B). 3
C). 2
D). 12
Answer:
In the mRNA sequence AUGGUGCAUGUC the maximum number of amino acids that can be encoded is 4 (option A).
Explanation:
Messenger RNA (mRNA) has a sequence of nitrogenous bases produced by the transcription of a DNA strand. This sequence of bases is organized in triplets or codons —made up of 3 nitrogenous bases— that can encode an amino acid, or mark the beginning or end —STOP codon—of protein synthesis.
From the sequence:
AUGGUGCAUGUC
Four codons are obtained, each of which encodes a different amino acid:
Codons: AUG-GUG-CAU-GUC
Amino acids: Met - Val - His - Val
Methionine Valine Histidina and Valine are the four amino acids encoded by the 12 nucleotide sequence of the mRNA.

Which system helps regulate body
temperature and water loss?
A. Outegumentary
B. Integumentary
C. Excretory
Answer:
b
Explanation:
Integumentary system helps regulate body temperature and water loss. Thus option B is correct.
What is the integumentary system?In our body integumentary system is present in the outer layer. It’s made up of your skin, nails, hair, and the glands and nerves on your skin. It acts as a physical barrier — protecting your body from bacteria, infection, injury and sunlight. It also helps regulate your body temperature and allows you to feel skin sensations.( like hot and cold.)
Integumentary system present in skin:-
Dermis, epidermis, Hypodermis
Integumentary system present in nails:-
Nail plate, Nail bed, Cuticle, Matrix, Lunula
Integumentary system present in hair:-
Hair shaft, Hair bulb
Functions of integumentary system:-
Provides physical protection against bacteria and germs.Protects you from the sun’s ultraviolet (UV) rays and sunburn.Helps you feel heat, cold and detect other sensations.Synthesizes vitamin D.
Hence, integumentary system is more important in body for the regulate temperature and water loss. Thus option B is correct.

During an infection, white blood cells travel to the infected site and phagocytize the pathogens. After phagocytosis, primary lysosomes fuse with the phagocytic vesicle to form a larger vesicle called a secondary lysosome. The reason for this is:
answer choices
a) to introduce antibodies to the phagocytic vesicles
b) to wrap the pathogen in additional membrane, rendering them harmless
c) to prepare the bacteria for export from the body
d) to mix the pathogens with strong hydrolytic enzymes and destroy them
Answer:
d) to mix the pathogens with strong hydrolytic enzymes and destroy them
Explanation:
phagocytosis occurs when a cell engulfs a molecule to break it down.
white blood cells are known as phagocytes as they ingest invading bacteria to break them down and destroy them.
The bacteria is first enclosed by a phagocytic vesicle that lysosomes fuse with on fusing lysosomes then break down the bacteria by mixing them with strong hydrolytic enzymes.

Which of the following is a way ATP is used in cellular processes? Select all that apply.
detoxification
muscle contraction
oxygen production
biosynthesis
polyatomic ions
Answer:
detoxification muscle contraction biosynthesisExplanation:
ATP, adenosine triphosphate, is a molecule high in chemical energy. It is made up of a ribose ring, the nitrogenous base adenine, and 3 phosphate groups in a phosphoester linkage at carbon 5
ATP is broken down, losing a phosphate group, and energy is released from breaking the phosphate bond. The other two phosphates in ADP are lined by stable p hosphoanhydride bonds.
[tex]ATP+H_{2}O[/tex] → [tex]ADP+Pi+free \hspace{0.1cm} energy[/tex]
In the body, ATP molecules are used to provide energy for detoxification in forms of active transport; fueling biosynthesis- the modification of different compounds to form macromolecules; and muscle contraction, providing energy to myosin, and braking myosin actin cross-linkages to free myosin for other contractions.
