Which explanation is most likely an effect of the evolution of a larger brain in humans? A larger brain allowed humans to use tools. A larger brain allowed humans to solve complex problems. A larger brain allowed humans to better survive disease. A larger brain increased humans' ability to fight.

Answers

Answer 1

Answer:

Answer:

The correct answer is the option: A larger brain allowed humans to solve complex problems.

Explanation:

Hello! Let's solve this!

Evolution shows that characteristics have developed over time that have allowed living things to survive in the environment.

In this case, it involves the size of the brain. The brain grew so that the human being could solve more complex problems.

We conclude that the correct answer is the option: A larger brain allowed humans to solve complex problems.

Answer 2

An organism is multicellular, has chloroplasts, and is made up of eukaryotic cells. In which domain would a scientist place this organism?

Answers

The answer is Eukarya.

There are three domains in the tree of life: Archaea, Bacteria, and Eukarya. Archae and Bacteria are Prokaryotes, unicellular organisms without a nucleus and organelles. Eukarya mostly includes multicellular organisms with a nucleus and organelles.
The mentioned organism is multicellular made up of eukaryotic cells and has organelles (chloroplasts). According to the characteristics of three different domains, the organism could be placed only in the domain Eukarya.

Which of the following statements is not true about the digestive system and its contribution to homeostasis? A. The digestive system helps to maintain the correct amounts of nutrients for the body tissues to do its job. B. The digestive system is responsible for monitoring the oxygen and carbon dioxide amounts in the blood and tissues. C. The digestive system breaks down food sources into the needed nutrients and deposits these nutrients into the blood for use by the cells. D. All of the above

Answers

Answer;

B. The digestive system is responsible for monitoring the oxygen and carbon dioxide amounts in the blood and tissues.

Explanations;

Homeostasis involves the maintenance of a constant body environment.

The digestive system is not responsible for monitoring the amounts of oxygen and carbon dioxide in the blood and tissues. (It is the function of the breathing system together with the circulatory system).

Digestive system instead helps maintain homeostasis in a number of ways, For instance;

-By changing the pH from the saliva for example, which makes the gastric environment acidic which helps the break down of food readily and fast and also protect the body from bacteria.

The statement that is NOT true about the digestive system and its contribution to homeostasis is: The digestive system is responsible for monitoring the oxygen and carbon dioxide amounts in the blood and tissues. The correct answer is B.

Sediments can be deposited by wind or water but water moves most.
Loess is wind deposited particles. Alluvium is water deposited soil.
The particles are one part but the place they settle impacts how they become rock because the geologic process will be different at the bottom of a deep marine sea than it is in a shallow off shore shelf.

Only the very smallest particles will be moved to mid-ocean but there will be many plankton and other organic deposits.

Coastal particles will vary in sizes . Water temperature will have more impact on the organic contributions here. Shallow tropical waters have coral and can form limestone.

Double fertilization results in the formation of select one:a. two diploid embryos and a haploid endosperm.
b. one diploid embryo and a triploid endosperm.
c. two diploid embryos.
d. one diploid embryo and a diploid endosperm.
e. two diploid embryos and a diploid seed coat.

Answers

Double fertilization results in the formation of one diploid embryo and a triploid endosperm. Double fertilization is characterized by the formation of two embryos; the embryo proper which is diploid and the fusion product of the central cell with one male gamete which is triploid. This secondary triploid zygote develops into the endosperm.
