Answer:
having fewer humans on earth would solve this
Explanation:
Answer:
Improving the energy efficiency of buildings to reduce emissions from heating/cooling.
Planting forests and tree to remove excess carbon dioxide from our atmosphere.
Reducing fuel emissions associated with motor vehicles.
Explanation:
Human activities contribute to climate change by causing changes in Earth's atmosphere in the amounts of greenhouse gases, aerosols (small particles), and cloudiness. The largest known contribution comes from the burning of fossil fuels, which releases carbon dioxide gas to the atmosphere.

Which describes the geological time of the first land plants.
Conifers appeared after the first flowering plants.
Conifers first appeared around 182 million years ago.
The first flowering plants appeared around 240 million years ago.
The first flowering plants were introduced toward the end of the Mesozoic era.
Answer:
D. The first flowering plants were introduced toward the end of the Mesozoic era.
Explanation:
Following the Paleozoic Era, the Mesozoic Era or Age of Conifers began approximately 250 million years ago. This major geological era brought about the ancestors of many of the plant and animal groups still in existence today.
The Mesozoic era is marked by 3 divisions:
the Triassic Period, the Jurassic Period, and the Cretaceous Period.Animals and plants slowly recovered after the mass extinction in the Permian-Triassic extinction that led to the eradication of most aquatic marine species. They evolved to exploit varying niches in their environment, leading to a boom in terrestrial animals. Over time the planet's increasingly warm climate, abundant in atmospheric oxygen and carbon dioxide, contributed to the growth of diverse megaflora, that rapidly dominated the planet's terrestrial biosphere.
By the end of the Mesozoic Era, in the Cretaceous period, flowering plants (angiosperms) largely replaced the dominant seed ferns of the Triassic, and the conifers, cycads and gymnosperms of the Jurassic.
Varied dispersal mechanisms in angiosperms co-evolved with the evolution of certain types of fauna. Plants used animal life, including herbivorous reptiles and early mammal-like species to disperse large seeds.
Answer:
D

The first flowering plants were introduced toward the end of the Mesozoic era. Also Did The Test

Explanation:
Methamphetamine increases the brain's levels of dopamine, __________ and __________.
a) norepinephrine, serotonin
b) GABA, epinephrine
c) acetylcholine, enkephalins
d) glutamate, serotonin
Answer:
a) norepinephrine, serotonin
Explanation:
Neurotransmitters are special lipid-based molecules used in chemical signal transduction in the nervous system. They have receptor-specific roles in activating different regions of the central nervous system (CNS) and physiological responses. These include: dopamine, norepinephrine, and serotonin .
The CNS, which includes the brain and spinal cord, can be affected by certain drugs like methamphetamine. This drug is a stimulant that acts on brain regions such as:
prefrontal cortex the striatumthe nucleus accumbensIt causes the release of neurotransmitters while blocking their reuptake at synapses; meth is metabolized very slowly over time (12 hours). The buildup of dopamine, for instance, leads to altered moods, feelings of pleasure and euphoria.
Thus, this change or "high" leads to dependency by users for its mood-altering effect; however, less dopamine is released, and the pleasurable effects, become less potent. Studies show neurological damage with prolonged use, and habit formation and over time, addiction.

The processes of the Rocky Mountains most likely required the longest period of time to occur is large uplift of the land from tectonic forces. Thus, option C is correct.
What are rocks?
When compaction and cementing happens then, a sedimentary rock is made. The rock is made when layers of minerals are stacked upon each other. These minerals include dirt, soil, sand, and other stuff. Overtime these minerals will make the layers that you see in a sedimentary rock. So, the older minerals will be on the bottom while the younger minerals will be on the top.
The Sedimentary rocks refers to the type of rock that is formed from pre-existing rocks or pieces of once-living organisms. They mainly emerged from deposits that accumulate on the Earth's surface and often have distinctive layering or bedding.
The common types of sedimentary rocks include sandstone, limestone, and shale. They often start as sediments carried in rivers and deposited in lakes and oceans and when buried, the sediments lose water and become cemented to form rock.
Therefore, option C is correct.

What a consequence brings the fact that the cerebral cortex is more developed in humans than in animals
Answer: humans have a very high brain-weight-to-body-weight ratio, but so do other animals. ... Other intelligent animals, such as monkeys and dolphins, also have these folds in their cortex, whereas mice have smooth brains, he said. Humans also have the largest frontal lobes of any animal, Holland said.

If the resulting F1 rabbits are crossed, what proportion of the F2 offspring will have the Himalayan phenotype and what causes the hypomorphic ch allele to be unstable and result in the distinctive fur pattern
Answer:
3/4; temperature
Explanation:
When animal are crossed to produce a different hybrid having the features or characteristics of both the two crossed animal, a hybrid offspring is produced. The hybrid offspring have all the qualities and characteristics of the parents.
When a parental cross is done between rabbit with albino rabbit, having genotype cc and with Himalayan phenotype that have a genotype of chch, it results in the production of F1 rabbits having all the Himalayan phenotype.
And if the F1 rabbits are now crossed, three-fourth of the F2 offspring have the Himalayan phenotype. The distinctive fur pattern and the unstable allele of hypomorphic ch is caused by the temperature of the surrounding.

describe the functional and comparative genomics
Answer:
Comparative genomics is a field of biological research in which researchers use a variety of tools to compare the complete genome sequences of different species. By carefully comparing characteristics that define various organisms, researchers can pinpoint regions of similarity and difference.
Functional genomics is a field of molecular biology that attempts to describe gene (and protein) functions and interactions. Functional genomics make use of the vast data generated by genomic and transcriptomic projects (such as genome sequencing projects and RNA sequencing).

what is the percent by mass of 8.0g copper is added yo enough zinc to produce 100g an alloy brainly
Answer:
8%
Explanation:
Given that,
Mass of solute = 8 g
Mass of soultion, (mass of alloy) = 100 g
We need to find the percent by mass of 8.0g copper is added to enough zinc to produce 100g an alloy. It can be calculated by the formula as follows :
[tex]\text{Mass}\%=\dfrac{\text{Mass of solute}}{\text{Mass of solution}}\times 100\\\\=\dfrac{8}{100}\times 100\\\\=8\%[/tex]
So, the percent by mass is 8%.
The percent by mass of the given copper in the alloy formed is 8%.
The given parameters;
mass of the copper = 8 gmass of the copper-zinc alloy = 100 gThe percent by mass of the given copper in the alloy formed is calculated as follows;
percent by mass of zinc = [tex]\frac{mass \ of \ zinc}{mass \ of \ the \ alloy} \times 100\%[/tex]
percent by mass of zinc = [tex]\frac{8}{100} \times 100\%[/tex]
percent by mass of zinc = 8%
Thus, the percent by mass of the given copper in the alloy formed is 8%.
