Ecologists are interested in quantifying different kinds of biodiversity. In each of the two studies outlined here, which kind of biodiversity are ecologists studying?

a. Ecologists draw blood samples from basking shark (Cetorhinus maximus) specimens caught from a single large population in the Atlantic Ocean. From each blood sample, the ecologists isolate DNA. Comparing several DNA sequences across the individuals that were sampled, the ecologists are able to estimate the variation in DNA sequences in the entire population.

b. Ecologists establish 20 small areas, called plots, randomly scattered across a California grassland. They count the number of different plant species present in each plot. By noting how many species appear in the plots, the ecologists are able to estimate the number of species in the entire grassland.

Answers

Answer 1

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.

How does a tree grow? Explain in detail

Answers

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.

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).

Answers

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.

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!)

Answers

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.

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).

Answer:

b. Pasteurized milk stored at room temperature for 4 days

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.

I think option B and C is correct answer

Mendel used pea plants as they were easy to grow and exhibit several distinct traits that vary.

Mendel's Experiment

Mendel'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.

A body is made of matter and matter is made of very small particles called molecules, which are constantly moving.

The molecules in a cold body move little but in a hot body they move more because we have provided heat.

When a hot body comes into contact with a cold body these things happen:
1) the hot body cools down (becomes cold).
2) the cold body heats up (gets hot).
3) both bodies reach the same temperature.

In summary, the heat passes from the hottest body to the coldest body until thermal balance is reached (the two bodies reach the same temperature).
