25. How do the excretory systems of animals that secrete uric acid differ from those of animals that excrete urine?
34. Explain why maintaining water balance is part of the process of excreting nitrogenous wastes.

thanks!!

Answers

Answer:

25.Nitrogenous wastes in the body tend to form toxic ammonia, which must be excreted. Mammals such as humans excrete urea, while birds, reptiles, and some terrestrial invertebrates produce uric acid as waste. Uricothelic organisms tend to excrete uric acid waste in the form of a white paste or powder.

34.The excretory system removes cellular wastes and helps maintain the salt-water balance in an organism. In providing these functions, excretion contributes to the body's homeostasis, the maintenance of constancy of the internal environment. When cells break down proteins, they produce nitrogenous wastes, such as urea

A disadvantage of sexual reproduction in plants is

Answers

Answer:

These are some of the disadvantages of sexual reproduction: time and energy are needed to find a mate.

hope this helps!

A disadvantage of sexual reproduction is the fact that ADDITIONAL ENERGY is required to complete a life cycle.

Sexual reproduction can be defined as a type of reproduction that involves a complex life cycle in which germinal haploid cells called gametes combine to produce a diploid (2n) cell called the zygote.

Subsequently, this zygote then divides to produce an adult organism.

In plants, the most important disadvantage of sexual reproduction is that energy is required to complete a complex life cycle (i.e., zygote development).

The diploid (2n) multicellular stage in the life cycle of a plant is known as the sporophyte.

In conclusion, a disadvantage of sexual reproduction in plants is that ADDITIONAL ENERGY is needed to complete a complex life cycle.

Which compound is a reactant of both cellular respiration and dehydration synthesis? (1 point)
O glucose
O oxygen
O water
O ATP

Answers

Answer:

glucose

Explanation:

I had a test with this, and it was glucose.

Glucose is a reactant of both cellular respiration and dehydration synthesis

WHAT IS CELLULAR RESPIRATION?

Cellular respiration is the process by which living organisms obtain energy from organic sources.

Cellular respiration combines glucose and oxygen as reactants to form carbon dioxide (CO2), water (H2O), and energy.

WHAT IS DEHYDRATION SYNTHESIS?

Dehydration synthesis is a reaction whereby two smaller molecules come together to form a larger molecule with the loss of water.

An example of dehydration synthesis reaction is the formation of starch from the reaction of glucose molecules with the loss of water.

Therefore, glucose is a reactant of both cellular respiration and dehydration synthesis.

Which question can be used to evaluate reliability of a source

Answers

Answer: The question can be used to evaluate the reliability of a source is Do these results support the author's own opinion?

In sources (books, articles, etc), reliability implies the information of a source can be trusted. This occurs if:

All the information is based on facts

The information is not manipulated by the author's opinion or interests

In this context, it is expected the information of the source is objective rather than influenced by the author's opinion. Therefore, one way to check the reliability of a source is "Do these results support the author's own opinion" because if the information is manipulated by a personal opinion, the source is not reliable.

Also, other questions are not appropriate because they are related to other aspects such as relevance, not reliability.

The answer as to which question can be used to evaluate the reliability of a source lies in the following options :

“Do these results support the author's own opinion?” “Is this data challenged by anyone in the public?” “Is this research relevant to me?” “Who was paid to do this research?”

The correct answer would be “Do these results support the author's own opinion?”

First, the reliability of a source refers to the level of dependability or trustability of the source.That a data is challenged by someone in the public does not make it more or less dependable, all other things being equal.Who is paid to do a research has no bearing on the reliability of the outcome as long as the scientific method is followed to the core.However, if a result supports the opinion of the author of the result, this might call the reliability of the result into question.

A result that reflects the opinion of its author might be scrutinized for confirmation bias. Hence, such a question can be sued to evaluate the reliability of a source.

7. Observations and inferences are
important in science. How would you
explain the difference between the
two words?


Answers

Hey there! I'm happy to help!

Observations are things that can be written down or described. You can observe something with any of your five senses: you can see what color something turns, you can hear the noise something makes, you can taste a cookie with a different amount of an ingredient, you can smell an odor produced by a chemical reaction, and you can feel the texture of different samples.

You can also create observations by using scientific tools. For example, instead of feeling if water is hot or cold, you could use a thermometer. This will give you numerical data which can be put into a table or graphed for further analyzing.

Inferences are created from observation. You cannot make an inference without observation. Observations lead to inferences. Inferences are conclusions or guesses made from the observations. You could infer that sugar makes a cookie taste sweeter after experimenting with no sugar and observing that it tasted bitter. You could infer that more weight allows things to travel further after going down a ramp after measuring the distances different weights travel, graphing it, and observing the data.
