Height of the tree upto which the squirrel climbed.
Solution-
Potential energy of a body = mgh
34.3 = 0.5×h (mg = 0.5kg)
h = 34.3/0.5

Answer:
The cell’s membrane separates the cytoplasm, forming two cells.
Explanation:
Cytokinesis is the physical process during cell division that separates the cytoplasm of the parental cell into two different daughter cells. Cytokinesis occurs after the telophase of mitosis. During this process, the cell membrane grows to surround each daughter cell and thus separate them. In animal cells, cytokinesis occurs by a ring of contractile microfilaments that lead to the constriction of the parental cell.

The fluid in glomerular capsule is similar to plasma except that it does not contain a significant amount of ________. The fluid in glomerular capsule is similar to plasma except that it does not contain a significant amount of ________. hormones plasma protein electrolytes glucose
Answer:
plasma protein.
Explanation:
An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).
This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.
Glomerular capsule is also referred to as Bowman's capsule and it can be defined as a cuplike sac (structure) with a double wall, which makes up the tubular part of a nephron within the kidney of mammals. It is saddled with the responsibility of first filtering blood (ultrafiltration) under pressure to generate urine in the mammalian kidney.
Plasma comprises of about 97 percent of water by volume and it typically contains mineral ions, glucose, carbon dioxide, hormones, plasma protein, etc.
Hence, the fluid in glomerular capsule is similar to plasma except that it does not contain a significant amount of plasma protein.

What are examples of things that can cause mutations?
Answer:
Exposure to chemicals.
Explanation:
Mutations arise spontaneously at low frequency owing to the chemical instability of purine and pyrimidine bases and to errors during DNA replication. Natural exposure of an organism to certain environmental factors, such as ultraviolet light and chemical carcinogens (e.g., aflatoxin B1), also can cause mutations. Hope this helped. :D

How many kingdoms are there in the domain Eukarya? O A. 1 O B.2 O c. 4 O D. 3
Answer:
There are 4 kingdoms
There are currently four kingdoms in the domain named Eukarya. The correct option is c.
What is domain?In biological classification, a domain is a taxonomic category above the kingdom level. Bacteria, Archaea, and Eukarya are the three domains of life.
These domains are defined by differences in cell structure, biochemistry, and other characteristics of the organisms that inhabit them.
Bacteria and Archaea are both prokaryotic domains, whereas Eukarya is a eukaryotic organism domain that includes animals, plants, fungi, and protists.
In biology, a kingdom is a taxonomic rank made up of smaller groups known as phyla (or divisions, in plants).
Historically, the highest taxonomic rank, or the most general taxon used in classifying organisms, is kingdom.
Animalia, Plantae, Fungi, and Protista are the current kingdoms in the domain Eukarya.
Thus, the correct option is c.

Carbon is transferred from the geosphere to the atmosphere by natural processes and human activities. Which of the following processes contributes to the transfer of carbon to the atmosphere?
A.
photosynthesis
B.
formation of fossil fuels
C.
precipitation
D.
volcanic eruptions
The processes which contributes to the transfer of carbon to the atmosphere are formation of fossil fuels and volcanic eruptions.
What is carbon cycle?The cycle in which transfer of carbon to the atmosphere from the Earth and back into the atmosphere is called carbon cycle.
Carbon is transferred from the geosphere to the atmosphere by natural processes and human activities.
Let's check all the options one by one-
A. Photosynthesis- This is a process through which the plants transfer light energy into chemical energy. In this process, carbon move from atmosphere to the biosphere.B. Formation of fossil fuels-The fossil fuels are developed by decomposing plants and animals in a million of years. This decomposition contributes to the transfer of carbon to the atmosphere.C.Precipitation- Precipitation is the product of water cycle, which falls by gravitational pull from clouds.D. Volcanic eruptions-The product such as lava and the gases which are released by a volcano is called the volcanic eruptions. These eruptions add carbon to the atmosphere.Hence, the processes which contributes to the transfer of carbon to the atmosphere are formation of fossil fuels and volcanic eruptions.

Brown eyes in humans are dominant to blue eyes. A brown-eyed man, whose mother was blue-eyed, marries a brown-eyed woman whose father had blue eyes. Figure out each member’s genotype
Answer:
Man: Bb
Man’s mother: bb
Woman:Bb
Woman’s father: bb
Explanation:
Brown eyes are dominant over blue eyes, so, in order for a person to have blue eyes, they must carry both recessive alleles for blue. This means the man’s mother and the woman’s father must have the genotype bb. The man and the woman on the other hand have brown eyes, which means they got the dominant brown eye trait from their other parent and will have a heterozygous genotype Bb.
