The tundra is cold year-round. it has short cool summers and long, severe winters. The tundra has a permanently frozen sublayer of soil called permafrost. Like the desert, the tundra receives little precipitation, about 4 to 10 inches per year, and what does fall is usually in the form of snow or ice. It has long days during the growing season, sometimes with 24 hours of daylight, and long nights during the winter. Which adaptations would you expect to see in plants growing in the tundra?
A) leaves with hair help shade the plant, reducing water loss.
B) small and grow in clumps for protection from the wind and cold
C) deep roots to help capture nutrients from deep below the surface
D) tall plants with broad, thin, waxy leaves leaves so water easily runs off

The correct answer is "compete".
Explanation:
The missing options of this question are:
compete
fight
work
The correct answer is "compete".
Populations are defined as groups of living beings that live in a certain location. Usually, the term population is used to describe groups of persons, but it applies for groups of animals and plants as well. Populations depend on an compete with each other, either for resources, new lands or because they are natural enemies. Populations are constantly competing, which is the base of natural selection.
Answer:
Populations depend on and compete with each other.
Explanation:
The competition between organisms and species is an interaction where both parties are harmed either by an external factor such as territory, water, food ...
Studies show that competition regulates demographic rates between species in an ecosystem.
And according to evolutionary theory, this competition for an external or internal factor is important for natural selection.
Consequently, competition requires species to adapt to change to survive or they will be in danger of disappearing.

What type of energy transformation takes place during photosynthesis?
A. Chemical energy is converted into light energy,
B. Chemical energy is converted into chemical energy.
c. Light energy is converted into chemical energy,
Answers
Answer:c
Explanation:the process of it
Answer: "C. Light energy is converted into chemical energy."
Explanation:
Photosynthesis is the process used mainly by plants by turning light energy (sunlight) into chemical energy (glucose + oxygen) that is later used to fuel themselves, similar to how humans eat food and drink water to fuel themselves.
The actual formula for photosynthesis is as follows:
[tex]6CO2 + 6H2O + light --> C6H12O6 + 6O2[/tex]

Shape
Answers
Answer:
Mass
Explanation:
Joseph is looking at how the mass, volume, and force of two objects compare to one another. When calculating the gravitational force between them and the mass of the object is taken into account.
What is gravitational force?Any two mass-containing objects are attracted to one another by gravitational force. In actuality, everything in the cosmos, including you, is pulling on every other object.
The mass of the objects and their separation from one another determine the gravitational force's strength.
The gravitational pull that different masses have on one another The force of gravity between the objects doubles if one of the masses is doubled grows, the gravitational force diminishes.
Therefore, studying the gravitational force mass of the object is necessary to study, hence option A is correct.

A scientist is studying the population of a particular species of beetle in an ecosystem. The beetles currently have an estimated population of 11,500 individuals on a wildlife preserve of 115 hectares. (One hectare is equal to 2.47 acres of land.) The scientist calculates the carrying capacity at 14,600 individuals.
Part A
Factoring a death rate from natural causes and predation, the beetle population increases approximately 5% each year. Use the Table button to create a table showing the estimated population for each year, starting with the current population and stopping when you’ve reached or exceeded the carrying capacity.
Answers
Answer/Explanation:
Given an estimated beetle population of 11,500, of which it is estimated to increase approximately by 5% each year, we can calculate the estimated population for each year as follows:
Year Calculation Est. Population
1st yr (current yr) 11,500
2nd yr 11,500*105% 12,075
3rd yr 12,075*105% 12,679
4th yr 12,679*105% 13,313
5th yr 13,313*105% 13,979
6th yr 13,979*105% 14,678
The above is how the table would like showing the estimated population for each year.
Answer:
To find the population of beetles each year, we multiply the previous year’s population by 105% (100% + 5%).
Year Population
1 11,500
2 12,075
3 12,679

What is the definition of photosynthesis
Answers
Answer:the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
Explanation:
Hey there!
Photosynthesis is the reaction that converts light energy to chemical energy in sugar and carbohydrates. Humans can't eat sunlight, so we eat plants. Plants convert the energy in the sunlight into chemical energy using chlorophyll. Chlorophyll is a molecule produced by plants, algae, and cyanobacteria, which aids in the conversion of light energy into chemical bonds. It is the green pigment found in the chloroplasts of higher plants. They are a part of our ecosystem, and they are lower on the food chain.

Answers
Answer:
Explanation:
does it give any other info on the woman or is that it?
The average temperature of an area can give a rough estimate of time since death, but other factors need to be considered for an accurate calculation. Consulting a forensic expert is essential.
Explanation:The average temperature of a given area can provide some insights into the time of death of a person. However, it is important to note that estimating the postmortem interval (time since death) based solely on temperature can be challenging due to many factors. In this case, the average temperature of 70°F in the area can give a rough estimate, but it would be necessary to consider other factors such as body temperature at the time of death, insulation, clothing, body composition, and external factors like shade or direct sunlight. Consulting a forensic expert would be vital in accurately estimating the time since the woman's death.

What would happen to the cell or organism if the protein is changed as a result of the mRNA being produced incorrectly?
A. The cell or organism will definitely have changes
B.The cell or organism may or may not have any noticeable changes
C.The cell or organisms life expectancy will drastically decrease
D.The cell or organism will not have any changes
Answers
Answer:
B. The cell or organism may or may not have any noticeable changes.
Explanation:
Some mutations can cause small changes, if any, such as different colored hair, or they can cause massive changes such as uncontrollable cell division, AKA cancer. Mutations are random so nothing is definite.
The mutation is the alteration in the nucleotide sequence or the proteins. If mRNA is incorrectly produced and alters the protein then there may be or may not be any noticeable changes. Thus, option B is correct.
What is mutation?The mutation is the state in which the bases or the amino acids coding the proteins during the mRNA translation are altered due to mutagens, genetic error, etc.
The mutation in the protein may or may not cause any change as some changes are not noticeable and very small, while some alterations may be big and dangerous.
Therefore, the mutation in the proteins may or may not be noticeable.
