As hominids evolved, their litter sizes decreased and their gestation period increased. Which of the following inferences can be made based on this observation?Reproductive success would increase, since mothers had to carry fewer offspring.
Hominids would have less difficulty finding mates, since competition is reduced.
Maternal care for offspring would increase due to a greater investment to protect.
Offspring would likely migrate in order to expand their territory and find mates.

Answers

Answer 1
Answer:

The correct answer is - Maternal care for offspring would increase due to a greater investment to protect.

During the hominid evolution, the litter sizes decreased and the gestation period increased, and that has resulted into a slower reproductive cycle. The smaller number of the litter means that the newborns are much more precious in the sense of the survival of the species, as any loss can have a very big negative effect on the future generations.

Because of that, the maternal protection, but also the protection of the father and everyone in the tribe is very big, and the young ones are well taken care of for much longer periods of time than before. That has made the hominid youngsters very dependent on the elderly for over a decade for their survival, thus prolonging their independence and ability to survive on their own.

D):Cell membrane

Hill is known for working out reactions taking place during the _____ of photosynthesis

Answers

Answer: The correct answer for the fill in the blank is Light dependent phase of photosynthesis.

Photosynthesis ( synthesis of food in presence of sunlight) is primarily divided into Light dependent and light independent phase.

Light dependent phase occurs in the thylakoid membrane within chloroplast and the chemical reactions taking place in this phase are also called Hill reaction. Energy from sunlight is absorbed and converted into chemical energy in the form of ATP and NADPH and Oxygen is produced due to splitting of water in this phase.


Hill is known for working out reactions takin gplace during the light reaction of photosynthesis. The process was described by Robin Hill, a biochemist, who discovered that the process of creating oxygen was not the same one that turns carbon dioxide into sugars in plants during photosynthesis. His theories became the foundation for the understanding of photosynthesis.

Answers

Intelligence in general definition, is defined as the orientation of the individual's capacity to solve problems, make decisive decisions, respond to situations and how the individual perceives and faces the situation. Moreover, this becomes a subjective ideology when authors are quoted.

1. What's a stalactite? A. Large mound of dirt created by erosion
B. Poisonous mass found in caves that is formed by polluted water
C. Mound-shaped stone shaped by weathering
D. Dripstone produced by a buildup of minerals precipitated from groundwater
AND
2. Which of the following statements describes rill erosion?

A. The population increases next to a shoreline.
B. Sand along a shoreline is repeatedly picked up by waves.
C. Sediment is deposited by a river.
D. Running water cuts small channels into a slope.

Answers

1. D dripstone produced by buildup of minerals precipitated from groundwater. Water drips down from, for example, the roof of a cave and slowly leaves behind mineral deposits which form a shape similar to an icicle
  2. D running water cuts small channels into a slope Rill erosion is formed by soil removal from small streams of running water. They form based on how the water falls down a slope and tend to migrate to already depressed or softer areas of soil.
