13. Which human characteristic is the result of our genetic material?
a. values
b. gender
c. language
d. personality
Answer:
b
Explanation:
this is because the father has an XY chromosome while the mother has an XX chromosome which is then genetically shuffled to get the offspring
Gender is the result of our genetic material, this is due to the genetic shuffle caused by the father's XY chromosome and the mother's XX chromosome, which results in the progeny, hence option B is correct.
What are sex chromosomes?The X and Y sex chromosomes are present in humans and the majority of other animals. Males have both X and a Y gene in their cells, whereas females have two X chromosomes.
Sperm cells have either an X or Y genome, whereas all egg cells have an X, because of this setup, the male decides the sex.
Since it occurs in people, the XX/XY sex-determination system is the most well-known. The majority of other animals and some insects have the XX/XY system.
Therefore, a chromosome variety known as a sex chromosome plays a role in determining sexual orientation.

Joe When scientists analyze the fossil record, they find organisms that are similar to some organisms of today with noticeable changes. How does this help scientists to
interpret the past?
O A. It doesn't help them at all
B. It allows them to see how organisms have changed over time.
OC. It allows them to see how organisms have remained the same over time.
OD. It allows them to see that there is no relationship between the past and today.
Answer:
B
Explanation:
This allows them to see how organisms have changed over time by comparing fossils to current organisms, which can help scientists understand the organism more and why they lost or gained traits over time

Which two statements support the idea that energy is conserved in this example?
According to law of conservation of energy , statement B and D support the idea of energy being conserved.
What is law of conservation of energy?According to law of conservation of energy, it is evident that energy is neither created nor destroyed rather it is restored at the end of a chemical reaction .The law is now called as the first law of thermodynamics.
Law of conservation of mass and energy are related as mass and energy are directly proportional which is indicated by the equation E=mc².Concept of conservation of energy is widely used in field of chemistry, fluid dynamics.
Law needs to be modified in accordance with laws of quantum mechanics under the principle of mass and energy equivalence.This law was proposed by Julius Robert Mayer in the year 1842.

Paleozoic is not one of the 3 major periods of the Mesozoic Era
Hope that helps!
From 252 to 201 million years ago was the Triassic Period. Between 201 and 145 million years ago is the Jurassic Period. Between 145 and 66 million years ago was the Cretaceous Period, hence option D is correct.
What is the Mesozoic Era?54 million years of the Mesozoic Era, or 199.6 to 145.5 million years ago, are referred to as the Jurassic Period.
The Jurassic Period, so named after the Jura Mountains in France and Switzerland, where rocks from this era were first investigated, has gained widespread recognition.
The Cretaceous is the final part of the Mesozoic Era, lasting from 145.5 million years ago to 65.5 million years ago, and is characterized by the demise of the dinosaurs (except birds).
Therefore, the Paleozoic is not a period of the Mesozoic Era, hence option D is correct.

What is an Non-native or Invasive species do to the environment?
Answer:
They can destroy the ecosystem or out - compete a native species.
Explanation:
For example, if an invasive species of tree is taller than the native species of tree and therefore takes up more sunlight, leaving the shorter native tree not enough sun, then it will effectively kill the native tree.
Also non - native and invasive are not the same thing. A non - native species doesn't necessarily mean it's invasive. It is only invasive if it begins to have a significant impact on the ecosystem it is inhabiting.

A section of a chromosome that contains instructions for building a protein.
What is a gene?A gene is a specific section of DNA, a long molecule that carries genetic information, located on a chromosome. Genes contain the instructions that cells use to make functional molecules called proteins.
Proteins are large molecules that perform a wide variety of functions in the body, including speeding up chemical reactions (as enzymes), building and repairing tissues, and helping to fight infections.
The process by which genetic information in a gene is used to build a protein is called gene expression.
Thus, genes play a critical role in determining the traits and characteristics of an organism, and they are essential for the proper functioning of cells and tissues in the body.
