Answer:
What can be deduced of cell that have densely packed mitochondria and the cristae are very closely together is that its function requires large amounts of energy.
Explanation:
Mitochondria are cellular organelles in charge of energy production. In these organelles occurs oxidative phosphorylation and electron transport chain, whose final product is ATP, an energy molecule.
A cell with a large number of mitochondria, whose crests are very close together and tight, belongs to a tissue that has a lot of activity and its energy requirement is high.
An example of cells with densely packed mitochondria are skeletal muscle and heart muscle.

What is the function of tRNA?
a bring an amino acid to the ribosome
b catalyze the assembly of amino acids into a protein
c carry genetic instructions for building a protein
Answer:
[tex]\boxed {\boxed {\sf A. \ Bring \ an \ amino \ acid \ to \ the \ ribosome}}[/tex]
Explanation:
tRNA, or transfer RNA, plays an essential role in the process of protein synthesis (creation).
After DNA is transcripted and translated, the messenger RNA is created in the nucleus and sent to the ribosome. The mRNA has codons or sets of three nucleotides. Then, the tRNA enters. The tRNA has an amino acid (the monomer of proteins) and an anticodon (three nucleotides that are complementary to the mRNA).
The codon and anticodon create base pairs, and the amino acids attach to form a protein.
Based on this information, the best answer choice is A. bring an amino acid to the ribosome

What characteristic of water helps in regulating cell temperature and maintaining homeostasis?
Someone please help i need a claim, evidence, then a reasoning !
Answer:
The characteristic of water that helps regulate the temperature of the cells and maintain homeostasis is specific heat (Claim).
Explanation:
Specific heat is a physical property that is defined as the amount of heat needed to raise one gram of a substance by one degree Celsius. In the case of water, its specific heat is higher than that of other substances, being its value 4.186 joules/gram °C, or also 1 calorie/gram °C.
- Claim: The property of water that allows cells to regulate temperature and maintain homeostasis is specific heat.
- Evidence: a high specific heat value of water means that in bodies that possess this molecule in large quantities it is more difficult to raise the temperature
- Reasoning: Living beings are formed mostly by a high percentage of water, much of it in the intracellular compartment. The specific high heat of the water makes it difficult to have sudden changes in the internal temperature, even when the environmental temperature is high, which is a property of water that allows thermoregulation and maintains the balance or homeostasis.

The correct option is D. The brain, part of the nervous system, sends a message to the eyes to detect the ball and then the nerves swing the bat.
What is brain?
The brain is a sophisticated organ that manages every bodily function as well as thought, memory, emotion, touch, motor skills, vision, respiration, temperature, and hunger. The central nervous system, or CNS, is made up of the spinal cord that emerges from the brain.
There are two distinct parts of the central nervous system: gray matter and white matter. Gray matter in the brain refers to the thicker, outer layer, and white matter to the thinner, inner layer beneath. This arrangement is reversed in the spinal cord, where the gray matter is located within and the white matter is on the outside.
Therefore, The correct option is D. The brain, part of the nervous system, sends a message to the eyes to detect the ball and then the nerves swing the bat.

3. Tupai is part of the Leeward Islands. For years, people were not
allowed on this island. Recently, it has been opened to tourists. How
will increased development and human interactions likely affect
succession on this island?
A. Lichens will increase quickly, creating a climax community.
B. Mature trees will decrease, creating a pioneer community.
C. Biodiversity will decrease as the number of species decreases.
D. More diverse species will move into the area as biodiversity increases.
Answer:
C. Biodiversity will decrease as the number of species decreases.
Explanation:
When Tupai which is part of the Leeward Islands is opened up to tourists, the need for infrastructural development will arise in the area.
For instance, there will be a great need to build hotels and resorts for the tourists, hospitals to handle medical emergencies, houses for residents that may move into the area in order to provide essential services to the visiting tourists.
All these will further decrease the biodiversity in the area as entire communities of organisms will be displaced and ecosystems destroyed in the wake of infrastructural development. This will ultimately lead to a decrease in biodiversity and number of species.

The behavioral inhibition system(BIS) according to Jeffery Gray can be explained as neuropsychological system which gives the prediction of response from individual to signal of anxiety-relevant in a particular area or environment. He stressed that BIS have a relationship of sensitivity to punishment along with avoidance motivation. The The behavioral inhibition system is usually activated when individual is experiencing negative event/ stimuli, boring moments, or punishment. Then by the time the body respond to the cues of the negative stimuli involving punishment, then the (BIS) brings avoidance of the negative event. When there is activity of( BIS) then there will be heightened sensitivity to punishment as well as nonreward experience.
It should be noted that the behavioral inhibition system (BIS) is activated by danger signals arising from both the brain stem and the cortex resulting in the experience of anxiety.

Write the important of biology in our daily lives with respect to agriculture and industry
Answer:
Biology is an interesting subject that has been intriguing scientific minds for several centuries
Explanation:
Despite exponential developments in technology over the past few centuries, the origin of life on earth is still one of the biggest mysteries yet to be unraveled.
The basis of our very origin and existence on earth lies within the depths of the biological sciences. Biology has an endless array of species( at least as of now because there are an estimated 8.7 million species on earth out of which only 1.9 million species have been discovered, so there is a long way to go!).
Every creation which is a part of nature is so adorable and unique in its own way.
Biology exists every second - when we inhale and exhale each time, respiration is taking place within our bodies, each cell receives oxygenated blood and releases carbon dioxide and other excretory wastes.
Let aside other species, we haven't yet understood our own bodies completely!!How is it that our hearts work so tirelessly throughout our life span, how is it that we are able to interpret even minute emotions and gestures without even understanding the mechanism behind it!.How is it that each one of us is able to perceive things differently?What exactly is consciousness?..The list of questions seeking their answers is endless!
Biology helps us to sort things out and find answers to such questions.
Humans aren’t the only living things biology is concerned with. It also tells us all about plants and animals – how they live, what they’re made up of, and how they interact with mankind and each other. This enables us to make the most of our planet’s natural resources while trying to minimize the impact we have on the environment.

A 2. Which of the following are features that help scientists classify annelids into their respective classes? O presence of setae and tentacles presence of setae and parapodia presence of setae and septa presence of coelom and parapodia
Answer:
presence of setae and parapodia
Explanation:
Annelids are groups of organisms under the phylum "Annelida". They are organisms that possess the following characteristics or features: setae, parapodia, coelom, tentacles etc. However, via the possession of not of the setae and parapodia, annelids have been classified into four major classes viz: Polychaeta, Oligochaeta, Hiradinea and Archiannelida, on the basis of their setae and parapodia mainly.
- Polychaeta: possess numerous setae and parapodia
- Oligochaeta: few setae, no parapodia
- Hiradinea: No setae, no parapodia
- Archiannelida: No setae, no parapodia
Hence, the presence of setae and parapodia will enable the scientists classify annelids into their respective classes.
Answer:
presence of setae and parapodia
Explanation:
Scientists determine what class Annelids are categorized into based on whether or they have parapodia and/or setae.
