Euglena and several other protists that use their cilia or flagella to move around and gather food are classified along with the plant-like protists. What is the most logical conclusion that can be drawn from this grouping?
They are parasitic on plants and use the plant chloroplasts to photosynthesize.
They must also be able to gather energy through photosynthesis.
Their ancestors were plants that lost their multicellular characteristics.
There must be a point in their life cycle when they produce leaves.
Answer:
They must also be able to gather energy through photosynthesis.
Explanation:
Some algae are considered protists and have photosynthetic pigments in the body, such as certain species of Chlorela, Chlorogonium, Euglena and Navicula are able to grow normally in the dark or in a carbon-deficient environment provided they are supplied with substances. high energy and easily metabolizable chemicals such as fatty acids, acetates, carbohydrates, etc.
For this reason, we can say that Euglena and several other protists, as well as plants, must also be able to collect energy through photosynthesis.
Answer:they must also be able to gather energy through photosynthesis

What are the set of microtubles which move to opposite ends of the cell to aid in cell division called
Answer:
A centriole
Explanation:
is a small set of microtubules arranged in a specific way. There are nine groups of microtubules. When two centrioles are found next to each other, they are usually at right angles. The centrioles are found in pairs and move towards the poles (opposite ends) of the nucleus when it is time for cell division.

Answer:
1) In cellular respiration, water and carbon dioxide are products. According to the graph, the products have a lower energy level than their reactant counterparts. - ANSWER IS C
2)
3)
4) Cellular respiration releases carbon dioxide into the atmosphere. - ANSWER IS B
5) Anna is correct that all cellular processes that require energy require ATP, but those that do not require energy occur without ATP. However, the process of glycolysis requires the input of ATP energy.
For each cell of the body to perform its normal cell functions, ATP is the primary energy-driving molecule that must be present in the cell. As a result, ATP is referred to as the "energy currency" of the cell.
However, there may be some processes that do not necessitate the use of energy. Diffusion, osmosis, and other processes that occur along a concentration gradient are examples of such processes.
ATP is required for the processes of glycolysis and the Krebs’s Cycle. - ANSWER IS B
I hope this at least gets you a good start. I am still working on the other two answers, but had something come up that I needed to do. So I will be back with the other two answers in a bit!

Explanation:
why the dates on the geologic time scale are often changed and updated.
Answer:
Absolute time measurements can be used to calibrate the relative time scale, producing an integrated geologic or "geochronologic" time scale. ... The overall duration and relative length of these large geologic intervals is unlikely to change much, but the precise numbers may "wiggle" a bit as a result of new data.

Answer:
C.) The variable that is observed or measured by the experimenter.
Explanation:
The dependent variable is the variable that is being measured or tested in an experiment.
For example:
In a study looking at how tutoring impacts test scores, the dependent variable would be the participants' test scores, since that is being measured.

The small intestines of cows are similar in general structure and function to the small intestines of humans. In a cow, damage in the wall of the small intestine reduces the number of villi due to which the cow loses weight and becomes weak. What could be the reason for weight loss and weakness?
Answer:
Low absorption of nutrients into the bloodstream from digested food.
Explanation:
This question is regarding the small intestine of a cow, which is said to be similar in general structure and function to the small intestines of humans. The small intestine is an organ found in the digestive tract of the cow or human in this case. Its primary function is to absorb the nutrients from the food, that has undergone series of digestion, into the bloodstream.
The small intestine is able to do this with the aid of the finger-looking extensions found on its wall called VILLI. The villi further contains MICROVILLI, which together helps the small intestine absorb nutrients into the blood. Hence, in a case whereby damage in the wall of the small intestine of the cow reduces the number of villi, resulting in weight loss and weakness.
This damage to the intestinal wall will cause a disruption in the absorptive function of the small intestine due to the reduced number of villi. Therefore, THE INABILITY OR LOW ABSORPTION OF NUTRIENTS INTO THE BLOOD THAT THE DAMAGE CAUSES is responsible for the weight loss and weakness in the cow.
The reason for the weight loss and weakness is as a result of decreased
absorption of nutrients from digested food.
The villi is a finger-like structure found in the small intestine which helps in
the absorption of nutrients from digested food into the bloodstream. When
the villi are reduced, the absorption of nutrients are reduced.
This thereby brings about weight loss as a result of nutrient deficiency
caused by low absorption into the bloodstream of the animal(cow)

Sea otters are a keystone species, they eat sea urchins which feed on sea kelp A large variety of species depend on the kelp forests for food
and shelter. Which species would be impacted by the removal of sea Otters?
Answer:
All species within that ecosystem would be affected.
Explanation:
Keystone species are species that other organisms largely depend on, if they disappeared, then all organisms within the ecosystems would be affected. For example: Sea urchins would overpopulate and over eat on sea kelp, which may threaten extinction in that area. Sea kelp dying would effect the organisms living/eating sea kelp

How are ammonia, nitrite, and nitrate levels in an aquarium correlated with one another
Answer:
Ammonia, nitrite and nitrate at higher levels are toxic to fishes in the aquarium.
Explanation:
Ammonia,nitrates and nitrites are all byproducts gotten from organic wastes which is biodegraded in the aquarium. These byproducts are gotten from fish and plant wastes, uneaten algae , bacteria e.t.c. There are bacterias in the aquarium that help to break down nitrogenous wastes in the aquarium.
Therefore, the waste from fish and plants are breakdown by bacteria into ammonia.
Ammonia at high levels are very toxic to fishes. Then the nitrifying bacteria then help to convert ammonia to nitrite.
Nitrite also at high levels is very toxic to fishes in the aquarium.
Nitrite is also converted to nitrate by nitrifying bacteria.
Nitrate is not very toxic and it is use by algae or plants for growth in the aquarium.
