I need help to answer these questions as well please

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.

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.

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.

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)

Answer:

Answer: are flawed

Explanation:

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.

Answer:

1. Transcription, Nucleus

2. Translation, Ribosome (Cytoplasm)

Explanation:

All living organisms contains genetic material in their nucleus (for eukaryotes), usually in the form of DNA. The DNA stores the information that encodes the synthesis of useful products (proteins). However, the encoded information needs to be expressed, which is done in two major stages namely: transcription and translation.

Transcription is the first process of gene expression which occurs in the NUCLEUS of eukaryotic cells, since the DNA is located there. Transcription involves the synthesis of a RNA molecule from a DNA template i.e. the information in the DNA is used to produce a RNA.

Translation is the second process of gene expression. In eukaryotes, the RNA transcript moves out the nucleus into the cytoplasm of the cell, where organnelles called RIBOSOME attach to it. In the ribosome, the RNA is used to synthesize amino acid sequence, which eventually becomes a PROTEIN. Hence, the information contained in the RNA molecule is translated into a protein molecule.

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 :)

Sorry, I would type more and give a better answer but I'm lazy and my brain works even worse at 12 am

Answer: A fatty acid in which the hydrocarbon molecules have a hydrogen atom every carbon and thus are fully hydrogenated. Byway of comparison the hydrocarbon molecules of unsaturated fats have two carbons that share double or triple bonds and are therefore not completely saturated with hydrogen atoms.

Explanation:

After the sperm successfully reaches to the woman’s egg it goes to the Fallopian tube and so on

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.

Answer:

individual - population- community- ecosystem

Explanation:

several individuals join to form population. community is organisms in a given unit area

and ecosystem is the living and non living organisms interacting each other in a given specific area

Homo erectus. it first spread through africa and eurasia.

pls mark brainliest

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

Answer:

Autosomes is tge correct one Explanation:

Protein

It’s on ape x

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.

Answer:

Explanation:

Answer: Wool, chemicals, soaps and other substances can irritate the skin and cause itching. Sometimes the substance, such as poison ivy, parasites or cosmetics, causes an allergic reaction. Also, reactions to certain drugs, such as narcotic pain medications (opioids) can cause itchy skin.

Explanation:

Answer:

To protect your skin.

Explanation:

The itch sensation is technically known as pruritus, and it's thought to have evolved as a way to protect skin - our largest organ - from parasites and build-up of dead cells.

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.
