Suggest two specific reasons why determining the cause of death can sometimes be difficult.
Answer:
1. The person has been dead for a while so the body is old.( Decomposed)
2. The manner or cause of death (injuries)
Explanation:
1.
Determining the cause of death could be difficult if the person has been dead for sometime. This is going to make the body to be more decomposed since the body has become old.
2.
Another reason is if the cause of death is from an accident and the dead person sustained great injuries. The condition of the body would be poor and this is going to make examination difficult.

Are gender traits completely a result of societal expectations?
[tex]\huge\star{\underline{\mathtt{\red{A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}}\star[/tex]
No. Gender traits in humans are largely determined by biophysical processes. There seems to be a vocal political faction that is trying to convince people in the name of liberty and equality that gender traits are completely learned, and therefore arbitrary.
But this claim disagrees with scientific evidence. In general, boys play more with cars and girls play more with dolls not because their parents are perpetuating outdated gender stereotypes, but because their brain is telling them to.
This fact does not mean that boys have to play with boy toys, or that boys who play with dolls aren't really boys. It is just a scientific observation about average behavior and its link to fetal development

A change in the nucleotide sequence
produced during DNA replication
DNA is a dynamic and adaptable molecule. As such, the nucleotide sequences found within it are subject to change as the result of a phenomenon called mutation. Depending on how a particular mutation modifies an organism's genetic makeup, it can prove harmless, helpful, or even hurtful.

Which statement correctly describes the flow of energy in photosynthesis?
A Photosynthesis releases energy when carbon dioxide and water combine to form glucose molecules.
B Photosynthesis releases energy when the reactants rearrange and form the bonds in the products,
Photosynthesis stores energy because energy is released when glucose is formed from carbon dioxide and water.
D Photosynthesis stores energy because more energy is stored in glucose than it is in carbon dioxide or water.
Answer:
Photosynthsis stores energy because more energy is stored in glucose than it is in carbon dioxide or water is the correct answer.

Natural selection causes what to occur?
1. evolution
2. survival of the fittest
The law of independent assortment
3. Mendel's law of segregation
4. genetic drift
Answer:
(1.) Natural selection causes evolution to occur.
Explanation:
Over time, the naturally occurring variation within a population that arise from mutations, alter in frequency. Some of these variants or traits, may confer advantages to certain organisms, allowing them to reproduce and pass on genes more successfully. These traits become fixed within the population, and eventually the individuals evolve to form a species.
Natural selection, acts on evolution, for or against traits. It ensures that individuals with traits well-suited to their environments and reproductive fitness survive.
Answer:
1. evolution
Explanation:
Natural selection causes populations to become adapted, or increasingly well-suited, to their environments over time. Natural selection depends on the environment and requires existing heritable variation in a group.

What are the three forces that drive (create and cause to continue) ocean currents?
Answer:
The rise and fall of the tides. Tides create a current in the oceans, which are strongest near the shore, and in bays and estuaries along the coast. ...
Wind. Winds drive currents that are at or near the ocean's surface. ...
Thermohaline circulation.
Explanation:
The three forces that drive (create and cause continuing) ocean currents are wind, water density differences, and tides.
What are ocean currents?Gravity, wind, and water density all contribute to the continuous, predictable, directed movement of seawater known as ocean currents. Water in the ocean can move both horizontally and vertically. Horizontal movements are referred to as currents, while vertical changes are called upwellings or dwellings.
The three main water flows in oceans are waves, tides, and ocean currents. Waves are produced by the wind's effect on the ocean's surface. The temperature difference between the warmer equator and the cooler poles causes ocean currents.
Therefore, the three factors of wind, water density variations, and tides are what drive (make, generate, and sustain) ocean currents.
