Answer:
Kristin's answer is the best.
Explanation:
It is the only correct answer.
The student that best explains whether Cell A or Cell B is a plant or animal cell is Kristin who said that "Cell A is a plant call because it has large vacuole in the middle of the cell to provide support, structure, and storage for the cell".
Distinctive features of plant and animal cellsCell is the structural and functional unit of the living organism which contains organelles that carry out specific functions.
The plant cells can be distinguished from an animal cell through the following features:
it possess a larger vacuole which is centrally placed and helps in the storage of cell wastes.It possess cellulose cell wall that provides support and structure to the cell.They also possess chloroplasts which are not seen on animals cells.Therefore, the student that best explains whether Cell A or Cell B is a plant or animal cell is Kristin who said that "Cell A is a plant call because it has large vacuole in the middle of the cell to provide support, structure, and storage for the cell".

The graph below shows the population of mice living in a certain area over fifteen years Which numeral on the graph points to a time when the birth rate exceeded the death rate of the mice?
I
II
III
IV
Answer:
I
Explanation:
In section I, the graph has a positive slope.
Birth rate - death rate = positive, the birth rate is more than the death rate
Sections II and IV have a balanced population where the birth and death rate are the same
In section III the death rate exceeds the birth rate
The numeral I on the graph points to a time when the birth rate exceeded the death rate of the mice.
What is death rate?The mortality rate, also known as the death rate, is a measure of the number of deaths in a given population per unit of time, scaled to the population's size.
The birth rate is the number of people born in a population in a given period of time. The number of people born per year per 1000 in the population is referred to as the human birth rate.
In section I, the graph has a positive slope. Birth rate and death rate difference is positive here, it means the birth rate is more than the death rate.
Sections II and IV have a balanced population with the same birth and death rates. Section III has a higher death rate than a higher birth rate.
Thus, the answer is numeral I.

What would happen if there were no greenhouse gases to trap heat?
Answer:
The Earth would be covered in ice and be about -18°C in temperature.
Explanation:
Greenhouse gases in the air, mainly carbon dioxide, methane and water vapour, trap radiation from the Sun and work as a thermal blanket around the planet. Without the Greenhouse effect, the Earth would be ice-cold.

The Pearson Correlation Coefficient is a tool used in understanding the behavior of gene expression. A positive ratio means a gene is induced in cancer cells and is transcribed at a higher rate. A negative ratio means a gene is suppressed in cancer cells or is transcribed less frequently than in normal cells. What form of gene expression do you think would lead to a correlation coefficient of one
Answer:
the gene is being expressed at an equal rate in both cell types
Explanation:
In statistics, the Pearson correlation is a linear measure of the association between two continuous variables. The Pearson's Correlation Coefficient may exhibit values between -1 and +1. A value equal to 1 shows a perfect correlation, indicating that when one variable increases the second variable also increases (when this value is +1) or decreases (when this value is -1). Moreover, when the Correlation Coefficient is equal to 0 it means that there is no correlation.
For each phrase below, choose the most appropriate key term from the list above
a. The improper or unsafe use of a drug
b. A drug that is inhaled as vapors
c. a drug that temporarily increases energy and alertness
d. drug withdrawal occurring in newborn infants
e. laboratory made drugs that closely resemble common illegal drugs in chemical structure and effect
f. a drug that slows the body and the brain
Answer:
a. Drug abuse
b. Inhalants
c. Stimulants
d. Neonatal abstinence syndrome
e. Club designer drugs
f. Depressants
Explanation:
Drug abuse can be defined as the excessive use of drugs that can be harmful to the individual or to others, which is associated with social, behavioral, physical and job-related problems. Inhalants drugs (e.g., glue, cocaine) are volatile drugs whose inhalation may induce psychoactive and/or mind-altering effects. Stimulant drugs (e.g., cocaine, amphetamines) are drugs that excite body functions by accelerating the activity of the central nervous system (CNS), while depressant drugs (e.g., alcohol) slow down the CNS. Neonatal abstinence syndrome occurs when a neonate withdraws from certain drugs (usually opioid drugs which interact with opioid receptors) to which he/she was exposed before birth. Finally, designer drugs (e.g., ecstasy, ketamine, LSD) are drugs synthesized in illegal labs which are commonly known as “club drugs” because they are often used and sold in nightclubs.

What is boiling factor ?
The boiling factor of a liquid varies in keeping with the carried out strain; the everyday boiling factor is the temperature at which the vapour strain is identical to the same old sea-degree atmospheric strain (760 mm [29.92 inches] of mercury). At sea degree, water boils at 100° C (212° F).
Thus it is well explained.

Explain how the formation of a submergent coastline differs from the formation of an emergent
coastline.
Answer:
One occurs when sea level rises whereas the other happens when the sea level drops.
Explanation:
The main difference between Submergent coastlines and emergent coastlines because Submergent coastlines formed when sea level rises or in other words, the land sinks down. Examples of submergent coastlines are estuaries, barrier bars, and barrier island systems while on the other hand, emergent coastlines occurs when sea level drops or the land rises. Hudson Bay and Eastern Coastal Plains are the examples of emergent coastlines.

What is biosphere?
The biosphere refers to the global ecological system that encompasses all living organisms and their interactions with the physical environment. It includes various interconnected ecosystems, such as forests, oceans, grasslands, and deserts, along with the diverse array of species and their habitats.
Climate change, with its wide-ranging impacts on temperature, precipitation patterns, and other environmental factors, can disrupt ecosystems and alter the distribution and abundance of species within the biosphere. These changes can have cascading effects on communities of organisms, populations of species, and the overall functioning of ecosystems. Therefore, the biosphere represents the highest level of organization that climate change can potentially impact.

1. Why should we care that the panthera tigris is going extinct? Explain how humans might be affected by the loss of the panthera tigris.
Answer: I believe tigers, also known as "Panthera tigris" are important to humans because they balance the ecosystem. When creatures go extinct they leave behind a scar that affects the ecosystem that is around them. Since Tigers are secondary consumers they control natural prey populations. The connection to the food web is very important and essential to keep this food web stable. Once something goes extinct it will cause the food web to shift and some primary producers will go out of control.
Explanation: Not sure if this helped at all this is just what I know about the food web. Panthera Tigris are secondry consumers so they control the primary producer population. This is just basic food web and ecosystem thinking. This is how they impact humans if they go extinct.

The principal reason we consider tunicates similar to the ancestor of all chordates is that Select one: a. tunicates have a lophophore-style mouth. b. tunicate adults are very similar to the ancestors of cephalochordates and vertebrates. c. tunicate larvae are primitive in all of their features. d. tunicate larvae possess the synapomorphies of adult chordates and thus reveal close evolutionary relationships with chordates. e. the body plan of adult tunicates parallels that of chordates.
Answer:
d. tunicate larvae possess the synapomorphies of adult chordates and thus reveal close evolutionary relationships with chordates.
Explanation:
In evolutionary biology, a synapomorphy is a shared, derived character/trait which is present in an ancestor and its descendants. Synapomorphies are useful markers to establish phylogenetic relationships between sets of taxa. Tunicates (subphylum Tunicata) are sessile marine invertebrates that are considered chordates (phylum Chordata) because the larval stage has characters/traits that are similar to other chordates. Larval tunicates have a nerve cord, a notochord, tail and gill slits (conserved in adults).
