Answers
Both facilitated-diffusion carrier proteins and cell-membrane pumps are specific to the types of substances they transport.
What is Facilitated diffusion?Facilitated diffusion is defined as the process of spontaneous passive transport of molecules or ions across a biological membrane by means of specific transmembrane integral proteins.
In facilitated diffusion, molecules diffuse across the plasma membrane with the help of membrane proteins, such as channels and carriers where a concentration gradient exists for these molecules, so they have the ability to move down (or out of) the cell.

In the jar she places a beaker that contains a solution of bromothymol blue. Bromothymol blue turns green in the presence of carbon dioxide .
She will record observations on Day 1, wait 24 hours, and record again on Day 2
Day 1 - Bromothymol blue solution blue. Soaked Seeds.
Day 2 - Bromothymol blue solution is green. Germinating seeds.
Which question has Kali MOST LIKELY ASKED as she set up this investigation?
A. Do germinating peas release oxygen in the process of respiration?
B. Do germinating peas release water in the process of photosynthesis?
C. Do germinating peas absorb water in the process of photosynthesis?
D. Do germinating peas release carbon dioxide in the process of respiration?
Answers
The increase in water level shows that respiration in the conical flask is causing gram seeds to germinate, which releases carbon dioxide. Thus, option D is correct.
What gases are released by germinating peas?The KOH solution in the little test tube absorbs the CO2 that the germination of the seeds in the conical flask releases during breathing.
As a result, a small vacuum is created inside the flask, forcing the water up the delivery tube. It demonstrates that seeds that are germination carbon dioxide during respiration.
By mixing glucose with oxygen from the air, organisms create energy during the process of respiration. Glucose and oxygen are converted into energy and carbon dioxide during cellular respiration.
During the process of cellular respiration, carbon dioxide is released into the atmosphere.
Therefore, germinating peas release carbon dioxide in the process of respiration.

The human TPM1 gene encodes members of the tropomyosin family of cytoskeletal proteins. Which of the following best explains how different proteins can be made in different cell types from the one TPM1 gene?
(A) Different introns are selectively converted to exons.
(B) Different exons are retained or spliced out of the primary transcript.
(C) The GTP cap is selectively added to and activates different exons. (D) Different portions of the primary transcript remain bound to the template DNA.
Answers
The fact that different exons are retained or spliced out of the primary transcript explains how various proteins can be made in different cell types from the one TPM1 gene.
TPM stands for tropomyosin, which codes for the Tropomyosin alpha-1 gene in humans. It makes up the skeletal filaments and has a role in controlling the contraction and relaxation of muscles.
The mRNAs transcribed from the DNA strand carry information for protein synthesis. Gene splicing happens after transcription, where a single gene gets modified to code for various proteins. This process helps in protein diversity.
The intracellular concentration of calcium ions and the binding of the ion to troponin causes conformational changes and results in actin-myosin bridge formation and subsequent contraction and relaxation of muscles.

A. A yo-yo and handshake
B. A see-saw , chin raise
C. A swing set , a leg kick
D. A slide, a squat
Answers
Answer: Option B.
A see saw, chin raise.
Explanation:
A lever is a machine that can rotate and consist of a beam which is pivoted to fulcrum.
There are three classes of lever, the first class lever, second class lever and third class lever. These three classes of lever are classified base on the positions of effort, fulcrum and Load.
In first class lever, fulcrum comes between the effort and load. Examples is scissors , see saw, pliers. This is because effort is applied on the one side of the fulcrum and load is on the other side. Therefore, the childhood demonstration of first class lever motion is see saw and chin raise.
In the second class lever, load come between effort and fulcrum e.g wheelbarrow, bottle opener.
In the third class lever, effort comes between fulcrum and load e.g hammer, broom.

Which of the following are a part of the circulatory system? I. Blood II. Lungs III. Heart IV. Blood Vessels A. I, II, III, and IV B. II, III, and IV C. I, III, and IV D. I and IV
Answers
Option A is correct as I, II, III, and IV are all a part of the circulatory
system.
The circulatory system, also known as the cardiovascular system, is a complex network of organs and vessels responsible for transporting blood, oxygen, nutrients, hormones, and other necessary substances to different parts of the body. It also plays an important role in the removal of metabolic waste and carbon dioxide from the body.
I. Blood is a vital component of the circulatory system that flows through the blood vessels and carries oxygen, nutrients, hormones, and other substances to different parts of the body.
II. Lungs are also a part of the circulatory system as they help to oxygenate the blood by allowing oxygen from the air to enter the bloodstream and carbon dioxide to be eliminated from it.
III. Heart is a muscular organ that pumps blood to the entire body. It is the center of the circulatory system and also responsible for regulating blood pressure.
IV. Blood Vessels include arteries, veins, and capillaries. Arteries carry oxygen-rich blood from the heart to the body and veins return oxygen-poor blood to the heart. Capillaries are small, thin-walled vessels where the exchange of oxygen, nutrients, and other substances takes place between the blood and the tissues.(option-a)

exaplian two situations on a pedigree that would allow you to determine the genotype of an induvudal with the dominant phenotype
Answers
1. If the individual with the dominant phenotype has an affected parent with a recessive phenotype.
2. If the individual with the dominant phenotype has affected offspring with a recessive phenotype.
In a pedigree, two situations can help determine the genotype of an individual with a dominant phenotype.
1. If an individual with the dominant phenotype has offspring with a recessive phenotype, it indicates that the individual must be heterozygous (carrying one dominant and one recessive allele).
This conclusion is drawn because the recessive phenotype can only be expressed when an individual has two copies of the recessive allele.
2. Another situation is when both parents have the dominant phenotype, but they produce offspring with the recessive phenotype.
This scenario suggests that both parents are heterozygous (carrying one dominant and one recessive allele), and the recessive phenotype appears in their offspring due to the inheritance of two recessive alleles.
By analyzing these patterns in the pedigree, we can make inferences about the genotype of individuals exhibiting dominant phenotypes.

Why do teens tend to make riskier decisions than adults?
Answers
Brain Development: The brain undergoes extensive development and reorganization during adolescence, particularly in the prefrontal cortex, which is responsible for decision-making, impulse control, and weighing consequences. This region develops at a slower pace compared to the reward-seeking regions of the brain, such as the limbic system. As a result, teenagers may be more driven by immediate rewards and less inclined to consider long-term consequences.
Sensation Seeking: Adolescence is characterized by heightened sensation seeking and a desire for novel and exciting experiences. Teenagers often seek out new sensations and engage in risk-taking behaviors as a way to explore their own identity, gain independence, and test boundaries. The pursuit of thrills and excitement can overshadow the potential risks involved.
Social Influence: Peer influence plays a significant role during adolescence. Teenagers are highly attuned to social acceptance and approval, and they may engage in riskier behaviors to fit in, gain peer recognition, or conform to social norms within their peer group. The desire for social status and acceptance can override concerns about potential negative outcomes.
Incomplete Experience and Judgment: Compared to adults, teenagers have less life experience and exposure to various situations, making it more challenging for them to accurately assess risks and make informed decisions. They may lack the cognitive tools and judgment skills to fully evaluate the potential consequences of their actions.
Emotional Intensity: Adolescence is a time of heightened emotional intensity, with teenagers experiencing intense emotions and seeking ways to regulate them. Risk-taking behaviors can serve as a means to cope with or regulate these emotions, providing temporary excitement, distraction, or a sense of control
Does the pharynx of human respiratory system have cartilage and epithelium?
Answers
Answer:

Explanation:
The pharynx of the human respiratory system does not contain cartilage.
The pharynx, part of the human respiratory system, is a muscular tube that connects the nasal cavity and mouth to the larynx and esophagus. It serves as a passage for air and food. The gorge is made up of several regions, each with its own distinctive features.
The nasopharynx, the top part of the throat, contains no cartilage. Instead, it is lined with pseudostratified ciliated epithelium.This special epithelium helps to trap and transport mucus along with any particles or pathogens in the digestive system for elimination.
These regions also lack cartilage but are lined with stratified squamous epithelium. This type of epithelium provides protection from mechanical stress and potential abrasion caused by the passage of food and other substances down the pharynx.
