Answer:
The correct answer is -
A. Genetic diversity.
B. Species diversity
Explanation:
In the first study, ecologists are studying the DNA sequences of the basking sharks and comparing the DNA they collected from the blood sample for finding the variation in DNA. The study of DNA and comparing the variations of DNA of a species is studying the genetic diversity of the species.
In the second study, the ecologists tried to study the different types of species present in small patches or plants, they created small patches of land, it is the study of species diversity.

7) Rank the following milk samples from most expected bacterial growth to least: Be sure to explain your rankings. (0.5 points) a. Pasteurized milk stored at 4*C for one week b. Pasteurized milk stored at room temperature for 4 days c. Autoclaved milk
Answer:
b. Pasteurized milk stored at room temperature for 4 days
a. Pasteurized milk stored at 4*C for one week
c. Autoclaved milk
Explanation:
Autoclaved milk has least expected bacterial growth because Autoclaved sterilization kills all the bacteria present in it so little chance of bacterial growth. Pasteurized milk stored at room temperature for 4 days has more bacterial growth due to favorable environment whereas little growth occur in the Pasteurized milk which stored at 4*C for one week due to less favorable environment.

Haley knows that plants and animals are made up of many different materials. She wants to know how these materials can cycle through an ecosystem.
What question could Haley ask to learn more about this topic?
A.
What kind of organism is the most popular at Haley's school?
B.
What happens to the materials that make up a living organism after it dies?
C.
What will happen to a sunflower plant if it is grown in a dark closet?
D.
What kind of plant should Haley buy her mom for her birthday
Answer:
B. What happens to the materials that make up a living organism after it dies.
Explanation:
An ecosystem can be defined as the natural living habitats of both living and non-living organisms.
Ecosystem services such as plant pollination, nutrient cycling and water purification are essential services that are being provided by the ecosystem. These services are really very vital, important and useful for the sustenance of life, both for humans, plants and animals because they enhance social welfare.
In this scenario, Haley knows that plants and animals are made up of many different materials. She wants to know how these materials can cycle through an ecosystem. Therefore, the question Haley could ask to learn more about this topic is; what happens to the materials that make up a living organism after it dies?
Basically, the material that make up a living organism decomposes after it dies and are then used up as nutrients by plants growing on the soil.

why do orangutans need so much space?
Answer:
Orangutans are the heaviest tree-dwelling animal
They spend most of their lives swinging through the canopies and need vast stretches of forest to find enough food and mates. Deforestation and hunting are the biggest threats to orangutans.orangutans need so much space because orangutans live in only a few places, and because they are so dependent upon trees, they are particularly susceptible to logging in these areas.Orangutans have large home ranges, which may overlap. Each adult female usually lives in a stable home range of about 3.5 square miles (9 square kilometers). An adult male's territory may be up to 15 square miles (39 square kilometers).

Sun burning can be seen as: a. the failure of an adaptation when normal (historical) environmental variation is exceeded. b. a misfiring of the mRNA system in cases where the ribosome is damaged. c. an adaptive response to avoid skin cancer. d. a result of too much vitamin D e. none of the above is correct
Answer: The correct option is E.
none of the above is correct
Explanation:
This is because sun burning refer to the over exposure of the skin to Ultraviolet radiations of the sun. It is as a result of too much exposure if the genetic content if the skin cells to Ultraviolet radiations of the sun and the symptoms include skin redness, the skin become swollen and sometimes wrinkled.
Describe the basic characteristics of organisms, including prokaryotic and eukaryotic, unicellular and multicellular, autotrophic and heterotrophic, and sexual and asexual reproduction, that classify organisms into the currently recognized kingdoms.
(Do NOT make a list. Write it as a paragraph!)
Answer:
Prokaryotes are those organisms which lack true nucleus and membrane bounded organelles while eukaryotes have true membrane bound nucleus as well as membrane bound organelles.
Unicellualr organisms composed of only one cell while multicellular organisms consists of large number of cells.
Heterotrophic organisms get their food from other organisms while autotrophic organisms synthesize their own food b with the help of photosynthesis.
sexual reproduction involves meiosis for production of gametes then fertilization and dvelopment while in asexual reproduction cells simply divide by mitosis and develops a new organism.
these ar the basic characteristics used for classifcation. plants are autotrphic multicellular sexually or asexually reproducing organisms, while animals are hetertrophic, multicellular and can also reproduce sexually as well as asexually.

Answer:
d. carbohydrates
Explanation:
The products of this equation actually belong to carbohydrates.
Carbohydrates are known to be a large group of organic compounds which is seen in foods and living tissues. Carbohydrates usually contain hydrogen and carbon and are in the ratio 2:1. When broken down, it releases energy which animals use for work.
Two known common carbohydrates are the starch and cellulose. They are macromolecules and are also polymers. Their monomers are units of sugar (glucose). Carbohydrates have the general molecular formula Cm(H2O)n (where m and n represent numbers).
Produces energy for the cell by converting glucose into ATP.

Why did the Vancouver Fraser Port Authority select Maplewood Flats as a restoration area to
offset their Centerm Expansion Project (CEP), rather than another location in Burrard inlet?
Select one:
a. Because it offers the greatest improvement in environmental conditions, sufficient to
match the damage caused by CEP, for the least expense.
b. Because it is the most species diverse site in the Burrard inlet
c. Because it is the most polluted site in the Burrard inlet
d. Because it has been identified as a significant anthropological and wildlife conservation
area
Answer:
a. Because it offers the greatest improvement in environmental conditions, sufficient to match the damage caused by CEP, for the least expense.
Explanation:
The businesses are required to restore the land to their original condition once they are with their business activities. The business operations often causes damage to the site and nearby land, for this reason restoration is mandatory in many countries. Vancouver Fraser Port Authority selects Maplewood Flats for the restoration activity because it offers the restoration at cheap cost.

Mendel used pea plants as they were easy to grow and exhibit several distinct traits that vary.
Mendel's ExperimentMendel's experiment was accomplished with the help of Pisum sativum, that is, the garden pea to study inheritance.
Mendel chose pea plants as they are easy to grow.
They also possess many visible features, which may vary.
These features comprise seed color, seed form, flower color, pod color and form, placement of flowers and pods on the stems, and length of the stem. Each of the feature has two common values.
Thus, the correct answers are options C and D.

How does a tree grow? Explain in detail
Answer:
Trees grow in height as a result of meristems that are located at their branch tips. These meristems are called apical meristems. ... The vascular cambium produces new xylem and phloem each year and as a result, the trunk, branches, and roots continue to increase in diameter.
Explanation:
hope this helps have a good rest of your day :) ❤
Answer:
in botany, a tree is a perennial plant with an elongated stem, or trunk, supporting branches and leaves in most species. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world.
