Explanation:
A laboratory experiment is an experiment conducted under highly controlled conditions (not necessarily a laboratory), where accurate measurements are possible.
The researcher decides where the experiment will take place, at what time, with which participants, in what circumstances and using a standardized procedure.
A snake species that has migrated from the mainland to a small island eats banana slugs instead of lizards and mice, its usual diet. Which statement best explains this change in behavior?
1. The genotype that affects food choice is not isolated to a single phenotype.
2. Instinctual food choice by snakes is not related to genotypic flexibility.
3. Diet is exclusively controlled by snake genetics, not by nature.
4. Gene expression for mainland snakes is rigid and confined to one phenotype.

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.

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.

Which answer best compares the end result of a cell that goes through meiosis to that of a cell that goes through mitosis?
A) The cell that goes through meiosis will have the same number of daughter cells as the one that goes through mitosis.
B) The cell that goes through meiosis and the one that goes through mitosis will both produces haploid cells.
C) The cell that goes through meiosis results in haploid cells, while the one that goes through mitosis produces diploid cells.
D) The cell that goes through meiosis will produce half as many daughter cells as the one that goes through mitosis.
Answer:
A
Explanation:The cell that goes through meiosis will have the same number of daughter cells as the one that goes through mitosis.
A
They will have the same number
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.

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).

Describe how epinephrine has different effects in different target tissues
Answer:
Epinephrine binds to receptors on some smooth muscles (ex: around arterioles) → Ca++ released from ER → intracellular Ca++ up → stimulates contraction. c. Epinephrine binds to receptors on some smooth muscles (ex: around bronchioles) → phosphorylates protein needed for response to Ca++, preventing response.

Explain how organisms can compete for abiotic factors in an ecosystem.
Answer:
An organism's niche includes food, shelter, its predators, the temperature, the amount of moisture the organism needs to survive, etc. When two or more individuals or populations try to use the same limited resources such as food, water, shelter, space, or sunlight, it is called competition.

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).

Complete question:
Beak Length in Finches
In a certain population of finches, a single gene controls beak length. There are two possible alleles: S, which leads to a short beak, and s, which leads to a long beak. Individuals with the genotype SS will have a short beak, individuals with the genotype ss will have a long beak, and individuals with the genotype Ss will have a medium-length beak. Scientists measure that in this population of 1,128 total birds, 321 birds have short beaks, 562 have medium-length beaks, and 245 have long beaks.

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. This will save company's cost and the land will be to its original condition with least possible damage to environment.
