Give an example of exaptation in humans.
Answer:
As an example of an exaptation, Gould (1991) used the large size of the human brain and its function of enabling humans to produce speech. The large brain size, according to his argument, originally arose as an adaptation for some (unspecified) functions in humans' ancestral past ( Gould, 1991 ).

Question: How is it that traits can vary so much in the same family?
Answer: One component, called shared environment, includes all environmental influences that make children in a family similar to one another.
Explanation: Environmental variance not due to shared environment is called nonshared environment; this portion of environmental variance makes family members different from one another.

Which of the following does not have an effect on enzyme activity?
Temperature
Amount of oxygen
Number of substrates
Shape of active site
Enzyme activity is based on various factors. Some of these factors are temperature, number of substrates and shape of active site.
What is enzyme activity?Enzyme is a molecule or a chemical that alters the rate of reaction. It can either increase or decrease the reaction rate.
The part of enzyme which binds to the substrate is called active site.
There are many factors that affect the enzyme activity, these are:
Temperature. pH.concentration.Number of the substrate.Shape of the active site.Thus the correct option is b.

4. I need help with this question
Answer:
F
Explanation:
A lake has very deep water at the bottom, in the benthic zone. Why is it more difficult for plants to live in the benthic zone of this lake than in the limnetic zone
Answer:
See the answer below
Explanation:
It is quite difficult for plants to survive in the benthic zone due to the limited penetration of light in the zone when compared to the limnetic zone. The limnetic zone is a well-lit area of a lake or pond while the benthic zone represents an area around the bottom of any water body - marine or freshwater.
Light is an important factor for plants because the light is necessary for photosynthesis - a process through which plants get their foods. Hence, due to limited light in the benthic zone as opposed to the limnetic zone, plants would find it easier to survive in the latter compared to the former.

Mendel came up with two principles? True False
All Archaea and bacteria are microscopic, prokaryotic organisms. However, Archaea and bacteria differ in significant ways. Which of the following is the MOST important reason that Archaea and bacteria belong to separate biological domains?
Archaea are often resistant to antibiotics
O Archaea do not have a nucleus
O Archaea are found as single cells or colonies
O Archaea often live in more extreme conditions than bacteria
The most important reason that Archaea and bacteria belong to separate biological domains is Archaea often live in more extreme conditions than bacteria.
What are the examples of biological domains?There are three domains of life, the Archaea, the Bacteria, and the Eucarya. Organisms from Archaea and Bacteria have a prokaryotic cell structure, whereas organisms from the domain Eucary encompass cells with a nucleus.
Examples include memory, mate choice, relationships between kin, friendship and cooperation, parenting, social organization, and status.
This phylogeny overturned the eukaryote-prokaryote dichotomy by showing that the 16S rRNA tree neatly divided into three major branches, which became known as the three domains of (cellular) life: Bacteria, Archaea and Eukarya.

define thigmotropism, phototropism, and gravitropism and give an example of each
Answer:
a) Thigmotropism
b) Phototropism
c) Gravitropism
Explanation:
A) the turning or bending of a plant or other organism in response to a touch stimulus. example: the folding movement of the Mimosa pudica leaflets, can be considered as an example of thigmonastism.
B) the orientation of a plant or other organism in response to light, either towards the source of light ( positive phototropism ) or away from it ( negative phototropism ).example: Sunflower is a highly phototropic plant. They grow towards the sun and are also seen tracking the movement of the sun throughout the day. That is, the flower keeps changing its direction with the movement of the sun. Sunflower requires more light for its growth and survival.
C) The gravity-directed growth process, called gravitropism, dictates upward shoot growth to ensure a proper positioning of the leaves for efficient photosynthesis and gas exchange. example: tree has fallen over and due to gravitropism exhibits this arched growth.

how do organisms with many cell types develop from a single cell
Answer:
A multicellular organism develops from a single cell (the zygote) into a collection of many different cell types, organized into tissues and organs.During development, cells use both intrinsic, or inherited, information and extrinsic signals from neighbors to "decide on" their behavior and identity.
Volcanic eruptions, breathing, decaying dead matter, burning fossil fuels, and warm bodies of water are all carbon examples of which of the following?
A) sources
B) sinks
C) reservoirs
D) all the above
Answer:
the answer is a
Explanation:
Volcanic eruptions, breathing, decaying dead matter, burning fossil fuels, and warm bodies of water are all carbon examples of sources. Therefore, option (A) is correct.
What are sources of carbon?Carbon is one of the most important elements for life on Earth, and it can be found in a variety of sources. Some of the most common sources of carbon include:
Fossil fuels: coal, oil, and natural gas are all made from carbon-based materials that have been buried and transformed over millions of years.Plants: Plants take in carbon dioxide from the atmosphere during photosynthesis and use it to build their tissues.Animals: Animals obtain carbon by eating plants or other animals.The ocean: The ocean contains dissolved carbon dioxide, which can be absorbed by marine organisms and transformed into calcium carbonate, a key component of shells and other structures.Soil: Carbon is stored in soil as organic matter, such as decaying plant and animal material.The atmosphere: Carbon is present in the form of carbon dioxide, methane, and other gases in the atmosphereLearn more about carbon sources, here:
