They are autotrophs - meaning they create their own energy from inorganic materials. They do this through a process called PHOTOSYNTHESIS.

Answer:

B. The make their own food through photosynthesis.

Explanation:

Plants convert energy from sunlight into sugar in a process called photosynthesis. Photosynthesis uses energy from light to convert water and carbon dioxide molecules into glucose (sugar molecule) and oxygen (Figure 2).

Answer:

Darwin noticed that the plants and animals on the different islands also differed. For example, the giant tortoises on one island had saddle-shaped shells, while those on another island had dome-shaped shells (see Figure below). People who lived on the islands could even tell the island a turtle came from by its shell.

Answer:

B

Explanation:

Gregor Mendel chooses to use purebred plants in his experiments because they exhibit only one form of a trait. The correct option is B.

Mendel altered pure pea plant lineages. First-generation hybrids (F1) displayed dominant qualities like purple flower color while hiding recessive traits like white bloom color.

But in second-generation (F2) pea plants, recessive characteristics returned in a 3:1 ratio (dominant to recessive). Every pea plant has both male and female reproductive organs, and they all typically procreate by self-pollinating.

This was crucial to make sure that there were no other factors influencing the result of the cross when he crossed two plants with different features.

Therefore, the correct option is B, They exhibit only one form of a trait.

Answer:

A. exposure - use of artificial sweeteners

disease - bladder cancer

In this research artificial sweeteners are used as the exposure that leads to bladder cancer disease.

B.                                 Bladder cancer          No bladder cancer

Artificial sweeteners      1293(a)                       855(b)

No artificial sweeteners  1707(c)                      2145(d)

Total                                3000                        3000

Cases -

- Risk factor (Artificial sweeteners) present (1293)

-   Risk factor (Artificial sweeteners) absent (1707)

Controls

- Risk factor (Artificial sweeteners) present (855)

- Risk factor (Artificial sweeteners) absent (2145)

Odds ratio or strength of association between exposure and disease

OR= Cases with exposure/cases without exposure= a/c divided by b/d

So, the putting value ad/bc= 1293*2145/855*1707

= 1.9

OR would be 1.9

C. this interprets that there is a 90% increase in the chance of bladder cancer if exposed to artificial sweeteners or people with bladder cancer have a 1.90 times higher odds of using artificial sweeteners compared to controls

Answer:

Electrons

Explanation:

Answer:

A current is a flow of electrons for this to happen there must be a closed circuit.

- The electricity is nothing but a flow of free electrons present in the external surface of the electricity conducting substance.

The flow direction of this electron flow is also the direction of electricity flow.

- There is a type of electrical circuit which is known as the closed circuit. This circuit is completely connected with the two terminals of the battery and there are no hindrances in the path of electricity flow in these circuits. That's why current can only flow through these complete circuits.

Answer:

A. True

Explanation:

We could just split the two parts of "extremophile'' and we get the gist.

"extremo-" (from Latin extremus) means to the highest degree of something.

"-phile" (from Greek philia), means love.

As a result, the term means "loving being in the highest degree (or something like that)."

To explain things, archaea are adapted to these extreme environments (hence the name extremophiles), except for hyperthermophily. Fungi, for example, live in mining areas, which are acidic and metal enriched.

Answer:

In transcription, the DNA sequence of a gene is "rewritten" in RNA. In eukaryotes, the RNA must go through additional processing steps to become a messenger RNA or mRNA. In translation, the sequence of nucleotides in the mRNA is "translated" into a sequence of amino acids in a polypeptide (protein chain).

Translation starts at a methionine (Met) codon, which specifies the amino acid methionine (Met). Translation stops at a Stop codon, which does not specify an amino acid.

Translation of an mRNA molecule by the ribosome occurs in three stages: a. initiation

b. elongation

c. termination.

During initiation, the small ribosomal subunit binds to the start of the mRNA sequence.

Translation happens in four stages: activation (make-ready), initiation (start), elongation (make longer), and termination (stop). These terms describe the growth of the amino acid chain (polypeptide).

Answer:

Because the organism is asymmetrical and it was able to regenerate, it’s probably (an amphibian), and belongs to the phylum (Mollusca).

In regeneration, the organism is asymmetrical and it was able to regenerate, it’s probably (an amphibian), and belongs to the phylum (Mollusca).

In plants and animals, regeneration is the natural process of restoring damaged or missing cells, tissues, organs, or even entire body parts to full function.

One of the processes by which an organism split into multiple pieces regrows to its original state is regeneration. Stem cells are specialized cells that carry out this process. It happens in life forms that have an exceptionally basic construction with not many particular cells.

Plants and animals can replace or restore damaged or missing cells, tissues, organs, and even entire body parts to full function through a natural process known as regeneration. Regeneration is being studied by scientists for its potential medical applications.

Answer:

D

Explanation:

The simple answer is the electrons in the outermost energy level.

Hydrogen has 1 electron in the outermost energy level.

Magnesium has 2 so this tells you that magnesium has a charge of 2

Oxygen has 6  oxygen has a charge of - 2

Fluorine has 7

For most elements, the electrons in the most outer ring determine the valence of the element.

Notice that the non metals work differently than the metals. Mg may have a charge of 2 and that is the number of electrons in the valence right.

Oxygen is a non metal it has a charge of - 2. It gets 6 electrons by subtracting the number of its charge from 8.

Answer:

D. electrons in the outermost energy level

Explanation:

The valence electrons are the electrons in the outermost energy level.

Answer:

B. 6 water + 6 carbon dioxide (+ light) --> 6 oxygen + glucose

Explanation:

Remember that in a chemical equation the reactants (input) are on the left and the products (output) are on the right. For photosynthesis to occur 3 different reactants are needed: water, carbon dioxide, and light. Note that because the light is not an element or molecule, it is sometimes written in paratheses or left out of the equation. Then, the products are glucose, which is the intended product, and oxygen, which is an unintentional byproduct that is released back to the atmosphere. Additionally, the equation for cellular respiration is the opposite of this, with the products as reactants and vice versa (except ATP is switched in for light).
