When examining the groupings for life on Earth, a student lists six major groups, including archaebacteria, true bacteria, protists,
fungi, plants, and animals. The student wants to organize the groups by similar features. The student knows that plants are
autotrophic and can photosynthesize to make their own food. Which other groups can be organized into the group that is considered
autotrophs because they have some species that can photosynthesize? Select ALL that apply.
A
Fungi
B
Animals
Protists
D)
True bacteria
Archaebacteria
Autotrops are the organisms that can prepare their own food by process called photosynthesis. True bacteria and some archaebacterias are the one performing photosynthesis like plants.
What are archaebacteria?Archaebacteria are a group of microorganisms evolved separately from the bacteria and blue-green algae.
Archaebacteria can also survive in extreme environment. Examples include Halobacterium, Pyrolobus, etc.
Both archaebacteria and bacteria are able to photosynthesize their food.
Thus, correct option is D.

Why are some elements such as hydrogen, often found as diatomic molecules?
Answer:
Hydrogen chloride, carbon monoxide, or nitric oxide do all have diatomic molecules. In essence, what that means is that they are all gasses at room temperature. Because their atomic nuclei have its origin in different elements, scientists refer to them as heteronuclear.
Explanation:
The backbone vertebrae, skull, and rib cage make up the _______ skeleton. Among other types of cells, bone marrow produces _______ blood cells, which carry oxygen in the blood. _______ can eventually become osteocytes. If bones rapidly deconstruct faster than new bone tissue grows, this can lead to less dense and more fragile bones. When severe, this condition is called _______. _______ such as the MCL and ACL connect bone to other bone at joints.
Answers :
axial
red
Osteoblasts
osteoporosis
Ligaments
Osteoblasts are cells that build bone tissue, and are called osteocytes when they become surrounded by the bone that they have built. Osteoclasts are cells that break down bone tissue. The building and breaking down of bone tissue continues throughout a person’s lifetime and makes bones strong. If osteoclasts break down more bone than osteoblasts build, this can lead to osteopenia and osteoporosis, causing bones to be fragile and break more easily.
Answer:
1. axial
2. red
3. Osteoblasts
4. osteoporosis
5. Ligaments
Explanation:
The axial skeleton consists of the bones of the head and trunk of a vertebrate including skull, and rib cage.
Bone marrow produces red blood cells, which carry oxygen in the blood.
Osteoblasts can become osteocytes, which are the third type of bone cells.
Osteoporosis is a bone resorption disease in which bones rapidly deconstruct faster than new bone tissue grows, and decreases the mechanical strength of bones.
Ligaments connects one bone to other at joint such as medial collateral ligament (MCL) and anterior cruciate ligament (ACL) that joins knee.
Hence, the correct answer for the question is as follows:
1.axial
2. red
3. Osteoblasts
4. osteoporosis
5. Ligaments

A student conducts an experiment to test how the temperature affects the amount of sugar that can dissolve in water. In the experiment, she uses 100 milliliters of water in each trial and stirs for five minutes each time.
What is the dependent variable?
the amount of water
the temperature of the water
the time stirred
the amount of sugar
Answer:
b is the correct answer
Explanation:
In the experiment, she uses 100 milliliters of water in each trial and stirs for five minutes each time, the dependent variable is the temperature of the water. Thus option B is correct.
What are the types of variables in experiment ?Variables are the measure, manipulating parameter used in every experimental study and it is a controlling agent in research. For example person's eye color, the value can change from brown to blue and it is depend on different factors.
Three major types of variables observed such as An independent variable which is a singular characteristic, Age is an example; A dependent variable which can be influence by the effect of other variable.
A dependable variable can be changed by independent variable, For example a grade on an exam is a dependent variable type mainly depend on Independent variables.
Control variable referred as the variable which remain constant and no effect on other variables but it is used to prevent bias in an experiment and provide accuracy of the result.
Thus option B is correct.

By performing photosynthesis, plants create everything they need to build all biomolecules. Is
this true? Why or why not? (1 point)
This is true because photosynthesis produces glucose, and plants only need
sugars, not amino acids or fatty acids.
This is not true because plants need to sequester nitrogen from the soil to
build amino acids.
This is true because photosynthesis produces glucose, which has carbon,
hydrogen and oxygen-the building blocks for all biomolecules.
This is not true because plants need to perform cellular respiration to break
down the glucose into carbon, hydrogen, and oxygen.
Answer:
This is not true because plants need to sequester nitrogen from the soil to build amino acids.
Explanation:
This is the answer i got on my quiz
This IS NOT TRUE because plants need to sequester nitrogen from the soil to build amino acids.
Carbon (C), Hydrogen (H), and Oxygen (O) are building blocks of carbohydrates. Plants must obtain Nitrogen from the soil, as well as phosphorous (P) and sulfur compounds (among other critical compounds), to sustain life.For example, DNA and proteins, which are critical biomolecules to sustain life, are composed of Nitrogen (N).Amino acids are the building blocks of proteins.In conclusion, the statement above IS NOT true because plants need to obtain Nitrogen from the soil to build amino acids.

describe how the human body maintains the carbon dioxide consetration in the blood when it rises above normal limits
Answer:
carbonic anhydrase helps to maintain the acid-base balance in the bloodstream and is present in high concentration in erythrocytes
Explanation:
as levels of CO2 in the blood begins to rise,the body can respond through hypoventilation or hyperventilation respectivelyAs degrees of CO2 in the blood begin to upward push, the body can reply through hyperventilation or hypoventilation, respectively. The CO2 is sure to hemoglobin paperwork a carbamino compound. In circumstances in which the CO2 and H+ concentrations are excessive, the affinity of hemoglobin for O2 is reduced.
How does the frame adjust the quantity of carbon dioxide within the blood?The blood consists of carbon dioxide to the lungs, where it's miles exhaled. As carbon dioxide accumulates in the blood, the pH of the blood decreases (acidity will increase). The mind regulates the quantity of carbon dioxide that is exhaled by controlling the rate and depth of respiration (airflow).
How does the frame alter blood oxygen ranges?The carotid frame represents an international oxygen-sensing mechanism in mammals. whilst the glomus cells within the carotid frame locate hypoxia, they may be depolarized and ship signals to the respiratory centers within the medulla oblongata to boom respiration price.
