Answer:

Evolution is an adjustment of the heritable attributes of natural populaces over progressive ages. These attributes are the outflows of qualities that are given from parent to posterity during generation. There are also three main types of evolution: divergent, convergent, and parallel evolution.

Explanation:

Classification is a method of grouping things together based on common qualities. Animal classification is critical since it aids in the identification and naming of all species on the planet. Animalia, Chordata, Mammalia, Primata, Hominidae sapiens are the classifications for humans.

Answer:

Because there are tens of thousands of genes in humans and other organisms, DNA contains a tremendous amount of information about the evolutionary history of each organism. ... It determines evolutionary relationships among organisms, and it indicates the time in the past when species started to diverge from one another.

Answer:

Neighboring Cells

Explanation:

Neighboring Cells are known to be the type of cells that influence development by controlling the fate of other cells in their local environment.

Typically Neighboring cells through the process often referred to as Induction simply influence the development of other cells nearby or in their local environment. This process of cell influence is either by direct cell-cell contact or through the release of practice chemical signals.

Hence, in this case, the correct answer is "Neighboring Cells."

Explanation:

The tRNAs contain I sound that base pair A C U advantageous to the species rabbit.

A form of RNA molecule called transfer ribonucleic acid (tRNA) aids in the translation of a messenger RNA (mRNA) sequence into a protein.

Translation, which creates a protein from an mRNA molecule, uses tRNAs at particular locations on the ribosome. A protein's amino acid composition is determined by codons, which are three-nucleotide mRNA sequences.

Every codon corresponds to a distinct amino acid, and every codon is accepted by a particular tRNA. The three hairpin loops that make up the tRNA molecule's characteristic folded structure give it the appearance of a three-leafed clover.

Therefore, The tRNAs contain I sound that base pair A C U advantageous to the species rabbit.

Answer:

I believe replication would not be possible, therefore the DNA would cease to help recreate cells which are essential to the human body.

Explanation:

This question by far is highly interesting, in fact it is very controversial too. However, with the sudden beginning of an actual hydrogen bond forming within nitrogenous bases, then replication would not be possible. This is so because replication relies only on nitrogenous bases rather than hydrogenous bonds. Therefore, resulting in a possible defect in the process of replicating to occur. However, if possible, I believe there might be even a chance of a mutation to occur, yet that is highly rare given the stance that the DNA molecule would not be able to pretty much do anything if that were to occur.

Ecosystem services of provision or supply

Explanation:

Ecosystem services

When talking about ecosystem services, we are referring to the benefits that ecosystems provide us. There are four types of ecosystem services:  

These are the products obtained by nature to be used or consumed, directly or with previous processing. Among them, we might mention food, clear freshwater, fertile soils, geotic materials (such as salt), raw materials (that can be used for clothing, construction), renewable fuels, biochemical compounds, pharmacological/medicinal resources, among others. Provisioning service has an impact on the economy, as many of these products are used to commercialize.  

Refers to ecological processes that improve life. Among others, we might mention climate regulation, CO² absorption, water purification, air purification, erosion control, natural disaster avoidance such as flooding, soil fertility maintenance, waste recycling, pests/plagues control, etc.  

Refers to not the material benefits. Ecosystems also provide a recreational place or area to spend time, to learn, provide a spiritual/religious space, are a source of inspiration. Ecosystems are considered to be cultural patrimony. Ecosystems are the source of scientific knowledge.

Involves ecological processes needed for the production of the other three previously mentioned services. There are five different support services:

→ Soil formation

→ Photosynthesis

→ Primary production

→ Nutrients cycles

→ Water cycle

Under certain circumstances, regulation services can also be considered support services.

Support service affects human beings indirectly, or direct but causing an effect in a long-term period.  

Answer:

Explanation:

i used a punnet square to calculate the output:)

Answer:

25%

Explanation:

There's a 50% chance of the offspring being male & 50% chance female. The genotypes must be co-dominant otherwise their question doesn't give enough information to get an anwser. Also a 50/50 chance of red/white, so added together a 25% chance.

A. Oxygen in the alveoli diffuses into the blood in the capillaries.

The overgrowth of microscopic algae is an algal bloom. The correct order is people overfertilize, excess nutrients transported by rain to nearby water bodies, excess nitrogen and phosphorus leads to algal bloom, algae overgrow, become overcrowded, decomposers that break down dead algae take in oxygen for cellular respiration and finally lack of oxygen causes death of fish and other aquatic life.

The overgrowth of microscopic algae or algae-like bacteria in fresh or salt, waters is referred to as algal bloom.

Depending on the type that cause it, an algal bloom may produce bad-smelling, foam, or a paint-like slick.

According to the given scenario, the correct order will be:

Explanation:

If we do end up colonizing Mars, Earth could slowly get better as time goes on, but when we do colonize Mars, wont we just do the same thing we did to Earth?

Answer:

Yes it could be, here are the pros.. Colonizing Mars is one of the most promising backup plans for humanity . Mars is relatively close to our Earth . Colonizing Mars may become possible in just a few decades . Many celebrities support those plans . Many scientists advocate for this kind of backup plan . Extraction of additional natural resources . May help with the search for other life forms . We could learn as global human species . Humanity needs challenges to progress . Knowledge is power . May help to mitigate the overpopulation problem on Earth . Colonizing Mars is an image project . Future generations would be able to adapt quite quickly on Mars . May be a good long-term investment for institutional investors

But there are also some cons.. Colonizing Mars is extremely expensive . It takes a while to travel to Mars ; Lack of water may become a serious problem . Plenty of insecurity involved in this plan . Completely different living conditions . Humans need protective equipment before going outside . It’s freezing cold on Mars . Some people have to make the beginning . May not be justifiable from an ethical standpoint . Colonizing Mars may conflict with religion . Money can be better used to solve our problems on planet Earth . Some scientists believe that efficient live on Mars will not be possible . Quality of life on Mars would be much lower . Rather insecure food supply . Radiation may become a problem . Still unclear if living on Mars is sustainable . We would alter the balance in our universe . Colonizing Mars can be dangerous . Space exploration implies significant pollution . Other life forms may not be welcoming towards us humans . Short-term costs vs. long-term gains

In conclusion, no it would not be a good idea.

Direct relationship.

Explanation:

There is direct relationship between growth rates and time which means growth rate of organism increases with the passage of time. Direct relationship means if one increases the other automatically increases and if one decreases, the other also decreases. The growth of bacteria becomes double when more time passes and vice versa. After every 20 minutes, the population of bacteria becomes double.

Answer:

* Glucose may cause an increase in bacterial growth - HYPOTHESIS

* The bacterial colonies grown without glucose don’t have capsules around their cells - OBSERVATION

* Bacterial growth in the glucose environment increased rapidly and then stopped after some time - OBSERVATION
