Answer:
d. theories are bases on sets of hypotheses
A scientific theory is a theory based on suggestions. It can change with the new evidences. Theories explain natural phenomenon. Thus, correct option is D.
What is a Scientific theory?A scientific theory is a model which explains the facts on the basis of observations and experimentation. A scientific theory can be proved by methods involving procedures, measurements, observations and evaluation of results. Scientific theory validates all the facts of nature and summarizes patterns found in nature.
Scientific theories are testable this means that new evidence should be compatible with a theory. If it is not then the theory is refined or rejected. A theory needs to be substantiated, explanatory, predictive, and testable.
A scientific theory is an explanation of some aspect based on a body of facts that have been repeatedly confirmed by observation and experiment.
Therefore, the correct option is D.

A. It increases the percentage of recombinants.
B. It results in 50% recombinants.
C. It reduces the percentage of recombinants.
Answer:
C. It reduces the percentage of recombinats
Explanation:
When linkage between two genes increases, the chance of these two crossing over is reduced, because linkage keeps these particular genes together, unlike crossing voer which will mix them up.

Although bipedalism is unusual, humans are not the only living bipeds. For example, some flightless birds are also bipedal. Identify a living nonprimate animal that is also a biped. Then, compare its bipedalism to our biped-alism.
Answer:
Explanation:
Human and birds as the basis for comparison. Some birds walk and run with their backs and femurs tilting at small angles to the horizontal and with bent knees while most human walk uprightly with legs straight and this can be seen in the duty and task performed by man.
Humans exert on the ground while walking two-peaked pattern of force which makes some human work very fast but Birds do not exact two-peaked pattern of force.
Human walking for individual with same body mass is relatively economical of metabolic energy while Bipedal locomotion is economical for wading birds, it is expensive for geese and penguins.

Question 29 (3 points)
Predict a change in the Earth's surface or effect observed at each of the following for
1 point each:
- TRANSFORM BOUNDARY
- DIVERGENT BOUNDARY
- CONVERGENT BOUNDARY
Answer:
Divergent boundaries occur along spreading centers where plates are moving apart and new crust is created by magma pushing up from the mantle. Picture two giant conveyor belts, facing each other but slowly moving in opposite directions as they transport newly formed oceanic crust away from the ridge crest.
Perhaps the best known of the divergent boundaries is the Mid-Atlantic Ridge. This submerged mountain range, which extends from the Arctic Ocean to beyond the southern tip of Africa, is but one segment of the global mid-ocean ridge system that encircles the Earth. The rate of spreading along the Mid-Atlantic Ridge averages about 2.5 centimeters per year (cm/yr), or 25 km in a million years. This rate may seem slow by human standards, but because this process has been going on for millions of years, it has resulted in plate movement of thousands of kilometers. Seafloor spreading over the past 100 to 200 million years has caused the Atlantic Ocean to grow from a tiny inlet of water between the continents of Europe, Africa, and the Americas into the vast ocean that exists today.

The cell membrane consists of ONE layer of phospholipids.
A. True
B. False
Answer: Hi there I think That I can help You!!!
The cell membrane contains a phospholipid bilayer, but the terms are not interchangeable. Part of the cell membrane is a phospholipid bilayer, made of two layers of phospholipid molecules. However, the cell membrane also contains other macromolecules like membrane proteins, and carbohydrates.
Explanation: So the correct answer is TRUE! don't forget to ate 5 stars and give brainlist!
The statement "the cell membrane consists of one layer of phospholipids" is absolutely false.
What is a Cell membrane?A Cell membrane may be defined as a type of biological membrane that significantly separates the interior components of the cells from the external environment. It also provides protection to the cell as well as other cell organelles.
A cell membrane is made up of a phospholipid bilayer. This illustrates that the two layers of phospholipid molecules are utilized in order to make an effective cell membrane.
It acts as selectively permeable in nature. The head or polar region of phospholipid is hydrophilic while the non-polar tail is hydrophobic in nature.
Therefore, the statement "the cell membrane consists of one layer of phospholipids" is absolutely false.

3) Part of a process necessary for reproduction in complex organisms is represented below. Step C results in the production of A) four zygotes that will develop into embryos B) embryonic cells that could unite and develop into an organism C) four cells that will recombine to form two offspring D) gametes that could be involved in the formation of a zygote
Part of a process necessary for reproduction in complex organisms is explained below, and the correct options are gametes that could be involved in the formation of a zygote, which is in option D.
What is a zygote?Reproduction in complex organisms involves a process called sexual reproduction, which involves the fusion of gametes from two parents, such as the male making the sperm and the female making the ovum, and then the zygote is formed. In the case of humans, this zygote develops into a baby after 9 months.
Hence, the correct options are gametes that could be involved in the formation of a zygote, which is in option D.

What is the adenosine triphosphate or ATP molecule?Adenosine triphosphate or ATP is a high energy molecule used by the cell to carry out different types of chemical reactions because this molecule releases energy that is coupled to the generation of other reactions.
The adenosine triphosphate or ATP molecule is produced mainly during the process of cellular respiration in an aerobic organism which requires the presence of oxygen. Moreover, anabolism occurs when polymers break down into monomers. while catabolism occurs when polymers are synthesized from monomers.
Therefore, with this data, we can see that the adenosine triphosphate or ATP is the energy coin of the cell which is mainly generated during a series of metabolic reactions called cellular respiration in organisms such as humans.
