'the fern are more terrestrially adapted 'explain this statement
Answer:
The reason for this is that both moss and fern species are relatively primitive plants that are only Imperfectly adapted to a terrestrial environment. ferns have both roots and vascular tissue and therefore, can grow larger than moss species, but like the mosses, ferns require water for reproduction.

true or false the typical X shaped chromosomes is the result of DNA replication
Answer:
True
Explanation:
Truly, the typical X shaped chromosomes is the result of DNA replication. When the DNA has replicated, it then condenses and coil into the X-shaped of the chromosome. This then implies that replicated chromosomes take the X-shaped structures seen under a microscope.
When this replication occurs, the chromosome is made of two structures that are identical. They are known as the sister chromatids. These chromatids are actually joined at the centromere.
How can humans mitigate the effects of human development on biodiversity?

The polar region (arctic and antarctic circles) is cold all year and experiences low precipitation.
What is the polar region?Any location on Earth that lies between the North or South Pole and the Arctic or Antarctic Circles is referred to be a polar region. The Arctic Ocean and a portion of several nearby land masses are included in the northern polar area, sometimes known as the Arctic.
Extremely cold temperatures, heavy glaciation wherever there is enough precipitation to create permanent ice, brief and cold summers, and extreme variations in daylight hours, with 24 hours of daylight in the summer and total darkness in the middle of the winter, are all characteristics of polar regions.
Hence, the polar region (arctic and antarctic circles) is cold all year and experiences low precipitation.

1. There are 2 types of rabbits in a population: those that eat grass, and those that eat flowers and berries. One
year, a drought occurs, and the plants have a hard time producing extras such as flowers or berries. They
can only try and keep themselves green. All year the rabbits have had babies, but many get eaten by
predators like foxes and hawks. Due to the drought, though, many have also starved. Explain what type of
natural selection will occur to this population of rabbits, including what trait is selected FOR and which is
selected AGAINST, and how the population will evolve as a result of the natural selection.
Answer:
Answer:
Against: rabbits that eat berries or flowers
For: grass eating rabbits
Explanation:
I hope this helps you out with your question! Can you plz consider marking me brainliest and thanks! Plz tell me how the answer was! It feel nice to be appreciated! Comment /free for a giveaway entry of 20 thanks and 2 brainliest. Have an awesome day! Let me know if you have any questions! -KaraYeaton18
Answer:
I'll explain it to make it easier on you :)
Explanation:
This type of natural selection is called disruptive selection. Because of the drought, foxes, hawks, and other animals eating the rabbits, the population of them is being disrupted Think of when a student is being disruptive in class. The teacher usually has to stop the class to 'punish' the student. This situation is similiar. There are things disrupting production and population of the rabbits.
FOR: The population of rabbits
AGAINST: The drought and predators
As a result of disruptive natural selection, the population of rabbits will only decrease due to predators and the drought.

23. What event most likely took place after photosynthetic organisms were introduced on earth? a. The atmosphere content changed from highly oxygenated to CO2 b. Mitochondria began converting glucose into ATP at a higher rate c. Oxygen was introduced into the environment allowing for many other organisms to survive d. The water cycle was thrown off causing super storms
Answer:
C. Oxygen was introduced into the environment allowing for many other organisms to survive
Explanation:
A is not correct because that is the opposite of what photogenic organisms do.
B is not correct because ATP and glucose do not apply.
D is not correct because photosynthesis does not have a direct affect on the water cycle itself.

Aquifer is the process of seeping of water under the ground.
Answer:
The process of seeping of water into the ground is called infiltration. The groundwater thus gets recharged by this process. At places the groundwater is stored between layers of hard rock below the water table. This is known as an aquifer.
Answer:
Explanation:
An aquifer is an underground layer of water-bearing permeable rock, rock fractures or unconsolidated materials (gravel, sand, or silt). Groundwater can be extracted using a water well. The study of water flow in aquifers and the characterization of aquifers is called hydrogeology.
You have purified the receptor for a hormone by affinity chromatography. During gel filtration chromatography under native conditions the receptor elutes between pyruvate decarboxylase (250 kDa) and glutamine synthetase (620 kDa). During SDS-PAGE, in the absence of reducing agents, the receptor migrates as a single band of approximately 230 kDa. When SDS-PAGE is carried out in the presence of 2-mercaptoethanol the receptor migrates as two bands of approximately 95 and 135 kDa. Explain this result.
Answer:
the hormone receptor is a heterotetramer composed of two subunits with 95 kDa and two subunits with 135 kDa
Explanation:
In this case, the heterotetramer is composed of two heterodimers, each composed of two subunits that held together by disulfide bonds. These heterodimers bind together through hydrophobic interactions in order to form a tetramer. The Sodium Dodecyl Sulfate (SDS) is a denaturing detergent that dissociates both heterodimers by interfering with hydrophobic interactions that hold heterodimers together. It is for that reason that only a single band of 230 kDa is observed (135 kDa + 95 kDa = 230 kDa). Moreover, 2-Mercaptoethanol breaks disulfide bonds, thereby separating the two subunits in the heterodimer. In consequence, after the use of this chemical compound (2-Mercaptoethanol), two different bands with 135 kDa and 95 kDa can be observed.

Explanation:
Option D:production of body heat: The skeleton serves six major functions: support, movement, protection, production of blood cells, storage of minerals and endocrine regulations. Hence, production of body heat is not a function of the skeletal system.
The major functions of the skeletal system are body support, facilitation of movement, protection of internal organs, storage of minerals and fat, and blood cell formation
How would an increase in the global surface air temperature affect the
water cycle?
Answer:
The answer is b because with more air the clouds would get more water and when the clouds get full it will rain and may cause a flood
Explanation:
i love your pfp by the way
Answer :
Climate change intensifies this is cycle because as air temperature increases, more water evaporates into the air. Warmer air can hold more water vapour, which can lead to more intense rainstorms, causing major problems like extreme flooding in coastal communities around the world.
