Type the correct answer in the box. Spell all words correctly. What is the source of continuous heat and energy that we receive from the Sun? The ____ chain reaction is the source of continuous heat and energy that we receive from the Sun.
Answer:
Nuclear fusion
Explanation:
Nuclear fusion powers our sun as nuceli fuse together and this reaction is exothermic (until some point), releasing energy which is light and heat.
What are greenhouse gases
and how do they contribute
to global warming?
Answer:
they contribute to global warming because the greenhouse gases affect the ozone layer making it having holes which allow more sunlight to reach Earth surface which results to global warming
Explanation:
they contribute to global warming because the greenhouse gases affect the ozone layer making it having holes which allow more sunlight to reach Earth surface which results to global warming
Answer:
"Greenhouse effect" is the warming of the climate that results when the atmosphere traps heat radiation from Earth towards space. Certain gases in the atmosphere resemble glass in a greenhouse, allowing sunlight to pass into the "greenhouse," but block Earth's heat from escaping into space. These gases that contribute to the greenhouse effect include water vapor, carbon dioxide (CO2), methane, nitrous oxides, and chlorofluorocarbons (CFCs). Carbon dioxide is responsible for 53% of the of global warming. It is the result of processes of the use of products such as fuel deforestation and production of cement and other materials. Its permanence in the atmosphere varies, but it’s very high at all times since 80% lasts for 200 years and the other 20% can take up to 30,000 years to disappear. Methane is the next of the greenhouse gases which has the biggest effect on global warming with 15%. This is produced by activities such as livestock production, agriculture, sewage treatment, natural gas and oil distribution., coal mining, fuel use and is also given off from waste tips, and lasts an average of 12 years in the atmosphere.
Hope this helps :)

Explanation:
Answer:upright man
Explanation:Upright man
Homo erectus
Homo erectus appeared about 2 million years ago and, in several early migrations, it spread throughout Africa (where it is dubbed Homo ergaster) and Eurasia. It was likely the first human species to live in a hunter-gatherer society and to control fire
Predict the most likely effect of a two-nucleotide deletion in the middle of the intron located between exons 4 and 5 on the structure of protein A. Justify your prediction.
Will mark brainliest!
Answer:
The question is incomplete; however, it is important to note that the deletion of two nucleotides in an intron generally doesn't have effect on gene function, thereby they are generally neutral.
Explanation:
Introns are gene regions that were historically considered as junk DNA because they do not encode for proteins, and therefore they were thought to have no biological function. However, in the last years, it has been discovered that introns are gene regions that encode non-coding RNA (ncRNAs), which are involved in gene regulation.

How were redi’s and pasteur’s experiments similar
Answer:
Both tested the idea of spontaneous generation.
Explanation:
The Redi's and Pasteur's experiment was performed to disprove the theory of spontaneous generation. They proved that life come from the pre existing life by working on the maggots and condition that originates the maggots from the flies.
Scientists must be able to repeat an experiment and get very similar results; otherwise their conclusions will be questioned. If the
results of a repeated experiment are different from the original results, the results of the experiment
Answer: are flawed
Explanation:
Punnett squares are grids that show:
A. the phenotypes of an offspring
B. All possible results of a genetic cross
C. Actual results of general crossing (mating)
What do you mean by endocytosis ? Answer me in ur own words
Answer:
Endocytosis means taking things in, or absorbing things. The prefix endo- helps me remember that.
Examples are pinocytosis and phagocytosis, which is where a cell envelops a food particle or a drink particle in its cell membrane and takes it into the cytoplasm to be digested and consumed.

I think the third one is right
Explanation:
How do substances like CO2 and water move in and out of the cell?
(Please Answer) :)
｡☆✼★ ━━━━━━━━━━━━━━ ☾
There are three processes you need to know of:
Diffusion, Osmosis and Active Transport.
Liquids (such as water) move via osmosis.
Osmosis is literally the movement of particles across a partially permeable membrane from an area of high conc to an area of low conc.
CO2 would move via either diffusion or active transport.
Diffusion is the movement of particles across the concentration gradient (i.e from high conc to low conc)
Active transport is the movement of particles against the conc gradient (i.e from low conc to high conc)

Which of the following describes surface tension in water?
Choose 1 answer:
Choose 1 answer:
(Choice A)
A
Surface tension occurs due to ionic bonding.
(Choice B)
B
Surface tension is caused by water molecules repelling one another.
(Choice C)
C
Surface tension allows water to support small objects if they are placed carefully on its surface.
(Choice D)
D
Surface tension of water is weakened by hydrogen bonding.
Answer:
C
Explanation:
Small objects usually do not permeate the surface of the water due to its high tension. The covalent bonding of water allows for its unique ability of high surface tension.

How does a genotype differ from a phenotype?
The sum of an organism's observable characteristics is their phenotype. A key difference between phenotype and genotype is that, whilst genotype is inherited from an organism's parents, the phenotype is not. Whilst a phenotype is influenced the genotype, genotype does not equal phenotype.
Answer:
What is the difference between a genotype and a phenotype? A genotype refers to the genetic characteristics of an organism. A phenotype refers to the physical characteristics. For example, having blue eyes (an autosomal recessive trait) is a phenotype; lacking the gene for brown eyes is a genotype.

The front legs of a cat and the arms of a human share a bone structure that suggests a common evolutionary lineage. Therefore, these skeletal structures are
Answer:
homologous
Explanation:
Since the front legs of a cat and the arms of a human share a bone structure that suggests a common lineage, these structures are said to be homologous.
Homologous organs are organs that share some similarities in different organisms but whose function differ in these organisms.
The organs are structurally similar but functionally different. Homologous organs represent one of the evidences scientists use to support evolution.
The front legs of cats and the arms of humans are functionally different, even though their structure is based on the same five digit plan.
