Answer 1

Answer:

tropicalis, or Western clawed frog. While the two can interbreed, the offspring survive only if the mother is African. With the occasional appearance of coydogs, pizzlies and ligers, it's clear that different species can often interbreed, even if the offspring are infertile.

Mitochondria
Cytoplasm

Answers

Answer:

Nucleus: blood

Cell Membrane: skin layer

Mitochondria; stomach

Cytoplasm: brain like structure

I'm not really sure of my answers.

Explanation:

The function of nucleus matches with that of brain and the function of cell membrane with that of Golgi bodies. Similarly, the function mitochondria is similar with that of liver and the function of cytoplasm is similar to that of skin.

What is a cell?

Cell is the basic unit of living bodies. A cell contains a nucleus, cell membrane, lysosomes, Golgi bodies etc.

Nucleus regulates all the functions of a cell as brain do in our body. Cell membrane helps to transport ions inside the cell as Golgi bodied do.

Mitochondria provide the energy and produce the chemicals needed for all chemical processes in the cell as liver do in our body.

Therefore, nucleus and brain matches in function and cell membrane and Golgi bodies matches in function. Similarly mitochondria and liver marches as well as cytoplasm and skin matches in functions.

Which of the following mechanisms of change in genefrequencies is responsible for the antibiotic resistance of E. coli in this experiment?

A. founder effect

B. natural selection

C. population bottleneck

D. genetic drift

Answers

Natural selection. It has evolved to survive against the antibiotic

Natural selection is the mechanism responsible for the antibiotic resistance of E. coli.

Natural selection is a mechanism that favors the adaptation of organisms to survive in their environment, thrive and reproduce.

In the context of antibiotic resistance, antimicrobial substances exert selective pressure on microbes that encourages the evolution of resistance.

Those capable of resisting the effects of antibiotics survive and reproduce, while the vulnerable either die or have their growth inhibited.

The excessive and inappropriate use of antibiotics favors selection for antibiotic resistance in bacteria.

E. coli is characterized by having Gram negative bacilli, it represents the greatest risks of zoonotic transfer of resistance.

In general, and when a treatment is short, there is an elimination of sensitive saprophytic strains of E. Coli and an enormous predominance of resistant strains.

Bacteria also acquire antimicrobial resistance through vertical or horizontal transfer of genetic information.

Therefore, we can conclude that resistance to antibiotics in E. coli is due to the process of natural selection since it evolves to resist the action of an antimicrobial agent.

- Named chemicals, including the end producys of fat digestion.​

Answers

Answer:

The majority of fat digestion happens once it reaches the small intestine. This is also where the majority of nutrients are absorbed. Your pancreas produces enzymes that break down fats, carbohydrates, and proteins. Your liver produces bile that helps you digest fats and certain vitamins.

Answer:

Triglycerides are large molecules, and unlike carbohydrates and proteins, they're not water-soluble. The digestive process has to break those large droplets of fat into smaller droplets and then enzymatically digest lipid molecules using enzymes called lipases. Digestion of fats mainly take place from fat enzymes produced in liver.

Due to the partial charges on atoms in a water molecule, ____ in water molecules are attracted to oxygen atoms in other water molecules.

Answers

Hydrogen bond in water molecules are attracted to oxygen atoms in other water molecules.

A hydrogen bond is a strong dipole-dipole attraction which occurs between:

the hydrogen atom attached to a strongly electronegative atom (for example oxygen in water molecules)another strongly electronegative atom with a lone pair of electrons

Hydrogen bonding occurs in the following compounds which include water, hydrogen fluoride and ammonia.

When an electronegative atom such as oxygen is bonded to hydrogen, a dipole develops causing the hydrogen to be partially positive while the other atom is partially negative.

Thus, this accounts for high boiling point in compounds that contains hydrogen bonds.

After three weeks, she measures the height of the seedlings and compares the two groups.Identify the parts of the experiment. Place only one term in each category. You will not place all the terms.

Answers

The purpose of this study is to determine the experimental group, the control group, the dependent variable, and the independent variable.

Designing and carrying out an experiment is the best approach to prove whether a hypothesis is true or incorrect. To ensure that an experiment examines exactly what the hypothesis claims, scientists must be cautious in how they construct it.

To ensure that only one factor is being altered in an experiment, the independent variables are therefore divided into two groups.

The control groupThe experimental group

The control group does not experience any changing variable.

The experimental group receives all of the experiment's circumstances, changes as well as the one variable that the experiment is testing.

In Ashley's experiment:

The experimental group:

Seedlings grown with coffee grounds.

The control group:

Seedlings grown without coffee grounds.

The dependent variable:

Seedling height

The independent variable:

Soil

Nitrogen-fixing bacteria are prokaryotic organisms that transform nitrogen gas into nitrogen compounds like ammonia and nitrates.

The graph that correctly shows the nitrogen-fixing bacteria in the soil is graph 2.

Nitrogen-fixing bacteria can be explained as:

Nitrogen-fixing bacteria are the organisms that fix the atmospheric nitrogen into the compounds of nitrogen as ammonia and nitrates.

The conversion of the atmospheric nitrogen is done in two steps, the first step involves the conversion of atmospheric nitrogen to ammonia. The second step involves the conversion of ammonium to usable nitrate.

Graph 2 represents the amount of atmospheric nitrogen decreasing with an increase in the amount of ammonia. It indicates that atmospheric nitrogen is utilized and converted into nitrogen compounds.

Thus, the correct answer is graph 2.

Stage 1 sleep is characterized by a predominance of ________ wave activity in the brain.

Answers

Answer: theta

Explanation:

Stage 1 sleep is characterized by a predominance of alpha and theta wave activity in the brain.

The stage of entering the state of sleep is also called stage 1 and is considered as a boundary between the waking state and sleeping.

In this stage, the rhythm alpha predominates, which tends to slow down and show the presence of waves called theta, which are of greater amplitude.

Alpha activity is a pattern that results from a person resting and relaxing.

Theta waves are broad, low-frequency waves that would indicate a state of extreme relaxation and drowsiness.

Eye movements at this stage are slow and muscle tone drops. Phase I is short-lived and occupies about 3-5% of sleep.

Therefore, we can conclude that in stage 1 of sleep the alpha waves would be combined, with a new activity, called theta.
