Answer:
The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases The absorbed energy warms the atmosphere and the surface of the Earth.
Explanation:
Hope this helps
Answer:
The atmosphere pretty much blocks the greenhouse gases from escaping, and it warms the Earth, hence global warming.

Since plant matter generates heat as it decomposes, where would a fire be most likely to start in the piles of grass?
Answer:
In the middle of the pile of grass.
Explanation:
The fire would be most likely to start in the middle of the piles of grass if spontaneous combustion occurs because the heat doesn't easily move through the medium due to the insulating nature of grass. A pile of grass can catch fire due to spontaneous and quick combustion in the middle of piles of grass. So the fire starts in the middle of the pile of grass.

Raquel is having difficulty becoming pregnant, and her doctor believes it could be due to the position of her uterus. Which organ should the body of the uterus be immediately superior to in the pelvis
The given question is incomplete, the complete question is:
Raquel is having difficulty becoming pregnant, and her doctor believes it could be due to the position of her uterus. Which organ should the body of the uterus be immediately superior to in the pelvis? Multiple Choice Urinary bladder Rectum Ovary Vagina
Answer:
The correct answer is urinary bladder.
Explanation:
In the pelvis, the urinary bladder is the organ to which the body of the uterus would be immediately superior. In the pelvis or the lower abdomen, a pear-shaped hollow composition, present between the urinary bladder and the rectum is known as the uterus. The structure or the composition located superiorly lateral to the uterus body and associated with the utero-ovarian ligament is known as the ovary. The vagina and the rectum are located underneath the uterus or the uterine cavity.

Consider substitutions accumulating at neutral loci (i.e., the fixation of mutations due to drift) in populations of two organisms, milkweed beetles with a huge population and mountain lions with a small population. In which organism would you expect substitutions to accumulate at a higher rate
Answer:
substitutions will accumulate faster in mountain lions
Explanation:
Genetic drift is the stochastic change in the allele frequencies in a population due to random sampling events. Genetic drift is known to produce the fixation of alleles (where allele reaches a frequency of 1) or loss of neutral genetic diversity in a population. Genetic drift conducts a population towards genetic uniformity over time. Neutral substitution refers to the emergence of a previously non-existent gene variant that arises by neutral mutations (i.e mutations that do not confer an adaptive advantage), which may be subsequently fixed or lost by genetic drift. The rate of neutral allele fixation is higher in smaller populations because drift (random sampling) is maximized, whereas in populations with infinite size fixation cannot be achieved. In consequence, neutral substitutions will accumulate faster in small populations than in large populations.

Which of the following is true concerning mangrove forests?
a. Mangrove forests are found at temperate latitudes.
b. Mangrove forests are not found at tropical latitudes.
c. Mangrove forests are named for the mangrove tree.
d. Mangrove trees are named for the mangrove forest.
Answer:
c.
Mangrove forests are named for the mangrove tree.
Explanation:
Salt Marshes and Mangroves
Edge 2020
Mangrove trees, which grow in these forests, are what give them their name, hence option C is correct.
What is mangrove forests?These trees are native to salty environments and coastal areas. These trees are effective water purifiers and provide fish with a breeding site.
Mangrove forests are fertile wetlands that grow in coastal intertidal zones. They are also known as mangrove swamps, mangrove thickets, or mangals.
Due to mangroves' inability to survive subfreezing temperatures, mangrove forests are primarily found in tropical and subtropical latitudes. Mangroves come in roughly 80 different species, all of which require soil with low oxygen levels to develop.
Therefore, Mangrove forests are named for the mangrove tree.

Forensic pathologists and anthropologists are usually able to identify the exact moment in time that death occurs.
A.
True
B.
False
Answer:
B. False
Explanation:
"Forensic pathologists" and "anthropologists" are usually unable to identify the exact moment in time that death occurs because they have to consider many factors in order to do so. Aside from examining the dead body's tissues, they also have to examine the other parts of the body (nails, blood, hair, etc.). The results will then be related to each other in order to tell whether the death was caused by a s.uicide, homicide and so on. They also need to collaborate with other specialists in order to arrive at a reasonable time of death. When they do, they just come up with a timeframe and not the exact time of death.

Answer:
It should be mostly in forest or in the ocean
Explanation:
Because, a forest is really crowded so some species wouldn't be visible to the human eye. And the ocean hasn't been fully discovered so we would be finding aquatic life the more we go deeper in the water.

How are matter and energy transformed during photosynthesis? Be sure to address carbon and chemical energy in your answer.
The glucose synthesised in photosynthesis is transferred to different animals and used by them to produce energy such as ATP. This explains the transfer of matter and energy during the photosynthesis process.
What is the photosynthetic reaction?Glucose and oxygen are the results of photosynthesis, which is carried out by green plants. Green plants and aquatic phytoplankton are the producers of the ecosystem.
The carbon dioxide and water are taken up by green plants, and the food (glucose) is synthesized. This food is the matter that is used for several cellular reactions to produce energy, which is ATP. Most of the ATP is produced by mitochondria via the Krebs cycle and electron transport chain.
The plant breaks down the water with the help of sunlight at Photosystem II (PSII), and an electron is released. The flow of electrons is helpful for proton gradient formation and ATP generation. The carbon dioxide that plants absorb is reduced or fixed at the stroma to produce glucose. This glucose is used by animals and plants themselves to produce energy.
Hence, glucose is transferred to animals, and ATP is produced as a result. It is chemical energy.

The Davson-Danielli model is a ______ model that shows the cell membrane is sandwiched between two layers of _______. A. true, lipids B. true, protein C. false, protein D. false, lipids
Answer:
The Davson-Danielli model is a false model that shows the cell membrane is sandwiched between two layers of protein .
Explanation:
In 1935, scientists Hugh Davson and James Danielli proposed a model of cytoplasmic membrane, which received their name.
The Davson-Danielli model explained that, in the structure of the cell membrane, the lipid bilayer was located inside a double layer of proteins, resembling a sandwich.
The characteristic of the proteins of being hydrophilic and the impossibility of these molecules to maintain their continuity in the exterior of the membrane put in doubt the viability of this model.
In 1972 it is proposed the model of fluid mosaic of the cellular membrane, by Singer and Nicholson, model that explains the structure of the cellular membrane —lipidic bi-layer and structural proteins— still in effect.
