In moving from the outside environment to the inside of a bacterium, the first layer encountered would be:__________

Answers

Answer 1

In moving from the outside environment to the inside of a bacterium, the first layer encountered would be Glycocalyx.

The cell coat or outermost first layer of bacterial cells is called the glycocalyx. Glycoproteins, glycolipids, and proteoglycans make up its composition. It is a network of lipids and membrane proteins connected by polysaccharide chains. On the lumen side, it encircles the vascular endothelial cells.

Various bacterium have varied glycocalyx layers with different compositions and densities. It serves as a protective layer and participates in cell interaction, signalling, and identification.

Answer:

Greatly affected.

Explanation:

The deer's behavior has greatly affected the survival and reproduction of these two  types of cactus because one cactus is eaten by deer while the other is saved from it. The cactus with no spines are eaten by deer which destroy the vegetative as well as reproductive parts of cactus so its survival and reproduction does not occur whereas the other cactus have spines on its body is save from deer and increase in the chances of survival and reproduction occur.

How many moles are present in 10, 0 grams of sodium hydroxide (NaOH )

Answers

Answer:0.250 mols

Explanation:

That’s the answer I got it wrong using the guy that previously wrote that the answer is 19 mols his totally wrong don’t trust him

We have that Moles that  are present in 10, 0 grams of sodium hydroxide (NaOH ) is

Moles\ NaOH =0.25moles

From the question we are told

How many moles are present in 10, 0 grams of sodium hydroxide (NaOH )

Generally the equation for the  Molar mass of sodium hydroxide is

[tex](NaOH) = (22.990 + 15.9994 + 1.008) \\\\ {(NaOH)} = 40 g/mol[/tex]

Where

Mass_{NaOH}taken = 10 g.

[tex]Moles\ NaOH =\frac{(mass of NaOH taken)}{(molar mass of NaOH)}\\\\Moles\ NaOH = \frac{10}{(40}\\\\Moles\ NaOH =0.25moles[/tex]

Therefore

Moles that  are present in 10, 0 grams of sodium hydroxide (NaOH ) is

Moles\ NaOH =0.25moles

What would happen to the production of the high energy sugars if water or carbon dioxide were not
available to plants?
ATD

Answers

Answer:

There would be no production of high energy sugars in the plant.

Explanation:

Plants produce their food (autotrophism) in a process unique to them called PHOTOSYNTHESIS. Photosynthesis is the process whereby plants produce energy-storing sugars (glucose) in the presence of light from sun.

This photosynthetic process combines Carbon dioxide (CO2) and water (H2O) as reactants to form sugar (C6H12O6) and oxygen (O2) as products. The equation for photosynthesis is as follows:

6CO2 + 6H2O → C6H12O6 + 6O2

This means that water and carbon dioxide are strictly needed for the process of photosynthesis to occur in plants. Hence, if water or carbon dioxide were not available to plants, there would be no photosynthetic process and ultimately no production of high energy sugars.

How is the brain involved with the senses and what is the relationship to the wat a personreacts to objects?

Answers

Answer:

The senses are the components of our nervous system that capture stimuli from the environment for transmission to the brain, and it is there where the information is processed to issue a response. All sensations are electrical signals that travel through neurons which form a network that communicates all organs with the center of the nervous system, and communicate with each other to transmit the electrical impulse through a process known as synapsis.

Explanation:

The brain is an organ that controls the activity of the body, both its conscious and unconscious functions. It is located in the head and corresponds, therefore, to the encephalon of humans and other vertebrates and is subdivided into forebrain, midbrain and hindbrain.  

The brain acts on the rest of the organism by generating muscle activity or by the production and secretion of chemicals called hormones. Thereby the brain controls responses to changes in the environment. Some basic types of response such as reflexes may be mediated by the spinal cord or peripheral ganglia, but sophisticated intentional control of behavior based on complex sensory information requires the integration of information.

The thalamus, which is located in the central part of the brain, processes and coordinates the messages from the senses that it receives from the body. Five senses are considered to exist: sight, touch, smell, taste and hearing. For that, the information perceived from the outside must reach the brain.

The senses are the components of our nervous system that capture stimuli from the environment for transmission to the brain, and it is there where the information is processed to issue a response. Therefore, all sensations perceived from the outside are electrical signals that travel through neurons. For example, the eyes transform light signals into electrical impulses, which travel to the brain where they are transformed into electrical signals.

Neurons form a network that communicates all organs with the center of the nervous system, and communicate with each other to transmit the electrical impulse through a process known as synapsis, which is mediated by molecules called neurotransmitters. Since the electrical impulse cannot jump directly from one neuron to another, these neurotransmitters are needed. When the active neuron produces them, the next neuron in the network detects them and becomes electrically charged. Once this has happened, it produces neurotransmitters again so that the next one becomes electrically activated. This is how the electrical impulse reaches the brain.

It is proper to put the _____________ allele before a recessive allele when determining the genotype of the offspring in a Punnett square.

Answers

Answer:

dominant

Explanation:

the dominant allele is the capital letter (for example, T) whereas the recessive allele is the lowercase letter (for example, t). the dominant allele is usually written first.

It is proper to put the dominant allele before a recessive allele when determining the genotype of the offspring in a Punnett square.

What are alleles?

Alleles are the variation present in the gene or DNA sequence. It is the sequence of nucleotides that encodes the production of the product of a gene.

There are two types of alleles, dominant and recessive, the dominant gene is denoted by a capital letter, and it is placed before the recessive allele.

Thus, in a Punnett square, the dominant allele should come before the recessive allele when determining the genotype of the offspring.

What is Water vapor?

Water vapor may be defined as the gaseous form of water that is usually dispersed across the atmosphere with the help of wind. This state of water is significantly found in the hydrosphere.

This gaseous form of water is formed from the evaporation or boiling of liquid water or from the sublimation of ice.

Water vapor requires to combine with dust particles and cool air along with atmospheric humidity in order to produce rain or snow. Due to the combination of such compounds, water droplets become too heavy.

Snow or ice is the solid appearance of water which is usually formed from the compaction of crystallized structure.

Please help!!!! Grizzly bears and polar bears are very closely related, so much so that they can reproduce to form hybrid offspring. Use your understanding of natural selection to describe how polar bears became a separate classification from the grizzly.

Answers

Scientists believe that at first these bears scavenged seal carcasses that had washed ashore, and gradually began to hunt the seals by waiting at the water's edge as the seals surfaced to breathe. This is believed to be an important step in the evolution of a new bear species, the polar bear

Over time the new polar bears were used to the cold climate and learnt how to fish, they then separated from the grizzly bears, they developed new creatures which would help them survive in one of the most dangerous climate.

Polar bears become separate classification from the grizzly by the natural selection known as divergent and adaptive evolutionary change.

Polar bears and grizzly bears are considered as closed to one another so they can interbreed. They both diverged from one another due to the harsh climate of the Arctic and the ecology of the region.

The changes that took place are camouflaging and pigment-free fur-coat that helped them in order to adapt to the different climates.The genetic mutation leads to such Adaptive changes when the polar bears migrated northwards.The populations living in different climates undergo natural selection that is divergent natural selection and the adaptive evolutionary changes that result in different species.
