Answer:
Explanation:
Index fossils (also known as guide fossils or indicator fossils) are fossils used to define and identify geologic periods (or faunal stages). Index fossils must have a short vertical range, wide geographic distribution and rapid evolutionary trends.
Index fossil, any animal or plant preserved in the rock record of the Earth that is characteristic of a particular span of geologic time or environment. A useful index fossil must be distinctive or easily recognizable, abundant, and have a wide geographic distribution and a short range through time. Index fossils are the basis for defining boundaries in the geologic time scale and for the correlation of strata. In marine strata, index fossils that are commonly used include the single-celled Protista with hard body parts and larger forms such as ammonoids. In terrestrial sediments of the Cenozoic Era, which began about 65.5 million years ago, mammals are widely used to date deposits. All of these animal forms have hard body parts, such as shells, bones, and teeth, and evolved rapidly.
What is the molecule depicted in the figure above and in which organelle would it most likely be created?
A. ATP, the mitochondria
B. ATP, the nucleus
C.ADP, the chloroplast
D. ADP, the ribosome
Answer:
The answer is A.
Explanation:
ATP, the mitochondria
The molecule depicted in the figure above is ATP and the cell organelle in which it would most likely be created is: the mitochondria.
Cell organelles can be defined as the internal organs that are typically responsible for the performance of various functions (tasks) within the body of a living organism such as an animal, plant, and humans, especially for the survival of the organism.
Some examples of cell organelles found in the body of living organisms include the following:
Nucleus. Cytoplasm. Cell membrane. Chromosome.Endoplasmic reticulum (ER). Golgi apparatus (bodies).Vesicles.Mitochondria.Mitochondria is commonly referred to as the "power house" of a cell because it is saddled with the responsibility of providing and transforming all of the energy required by living organisms in the form of adenosine triphosphate (ATP).
In conclusion, it is very important that energy (ATP) is provided by mitochondria for the survival and optimum performance of a living organism.

Explanation:
Nucleus is the organelle that houses the genetic material DNA.
What do you mean by organelle?
"An organelle is a subcellular structure that has one or more specific jobs to perform in the cell, much like an organ does in the body."
What do you mean by genetic material?
"Any material of plant, animal, microbial or other origin that carries genetic information and that passes it from one generation to the next is called genetic material."
What do you mean by DNA?
"DNA or deoxyribonucleic acid is a long molecule that contains our unique genetic code."
What is called a nucleus?
"A nucleus, as related to genomics, is the membrane-enclosed organelle within a cell that contains the chromosomes. An array of holes, or pores, in the nuclear membrane allows for the selective passage of certain molecules (such as proteins and nucleic acids) into and out of the nucleus."

Six white-tailed deer and six sika deer were enclosed in a pasture for observation during an eight-year study in central Texas. White-tailed deer are a native species to central Texas, while
sika deer are a nonnative species to central Texas. White-tailed deer feed on flowering plants and the tips of trees and shrubs but do not eat grass. Sika deer feed on flowering plants, the
tips of trees and shrubs, and grass. All other grazing animals were kept out of the pasture during the study. The number of sika deer more than doubled after the eight years, while the
population of white-tailed deer decreased by 50 percent.
Which of the following statements best supports the results from the study?
A
The sika deer are generalists, while the white-tailed deer are specialists.
B
The sika deer out competed the white-tailed deer in consuming flowering plants and shrubs.
с
Parasites infected the sika deer population but did not infect the white-tailed deer population
D
Change in the local climate reduced the availability of food resources for the white-tailed deer population

Why is using the presence of chromosomes inside of a cell NOT a reliable method to
determine if the cell is a prokaryote or a eukaryote?
Because both prokaryotic and eukaryotic cells have chromosomes (prokaryotes, and more specifically, bacteria, generally have just one chromosome, but there are some bacteria as well as archaea—which are also prokaryotes—that have multiple chromosomes).
Since the chromosomes are DNA molecules present in both the prokaryotic and eukaryotic cells, it is not a reliable method to determine if a cell is prokaryotic or eukaryotic
The nucleus of a eukaryotic cell is bounded by internal membrane, therefore, it is distinctive.
In contrast, the nucleus of a prokaryotic cell lacks internal membrane, hence its nucleus is not distinctive.
Chromosomes are Deoxyribonucleic (DNA) molecules that carry genetic information of a cell or organism.
The chromosomes are present in both the eukaryotic and prokaryotic cells. Chromosomes present in the eukaryotic cells are called eukaryotic chromosomes while chromosomes present in the prokaryotic cells are called prokaryotic chromosomes.
Since the chromosomes are DNA molecules present in both the prokaryotic and eukaryotic cells, it is not a reliable method to determine if a cell is prokaryotic or eukaryotic

D. Some traits in certain embryos disappear as the embryo develops
Explanation:
I don't know how I would explain it, but I can list some of the things that disappear such as... Gill slits, and tails. Hope this helped :D
Answer:
D. Some traits in certain embryos disappear as the embryo develops.
Explanation:
Embryology is the study of embryos. Embryos of different animals such as mammals, birds, fish, reptiles etc. look alike that is they are very similar. Many traits of one type of animal appear in the embryo of another type of animal.
Search the NIH gene database for the term colorblindness. Use the results of the database search to explain how a father and mother who are not colorblind could have a son who is colorblind. Your model can be a pedigree chart, a Punnett square, or a diagram of chromosomes.
Answer/Explanation:
Red/green colorblindness is a recessive, X-linked condition. That means that the affected gene is on the X chromosome, and that the phenotype will only be present if there is no "healthy" gene, which is dominant to the mutated gene.
For two unaffected people to have an affected son, the mother must be a carrier. Remember, females have two X chromosomes and males have one. So if a female is a carrier of the colorblindness mutation, she will have one copy of the mutation and one normal copy of the gene, and will therefore be unaffected.
The punnet square (attached) shows that all their female children would be unaffected (have the B gene), but 1:2 male children would be colorblind, as their only copy of the gene is mutated (b).

According to cell theory, which of the following are made of cells? Check all that apply.
- flowers
- rocks
- blood
- water
- bacteria
- sugar
- skin
Answer:
flowers
blood
bacteria
skin
According to cell theory flowers, blood, bacteria and skin all are made up of cells.
What is cell theory?The cell theory is a scientific theory that was initially developed in the middle of the nineteenth century, which states that all living organisms are composed of cells, that cells are the fundamental structural/organizational unit of all organisms, and that all cells originate from pre-existing cells.
Knowing that all living things are cells helps us comprehend how they are born, grow, and die. That information helps us understand how new life is produced, why creatures take their forms, how cancer spreads, how diseases can be handled, and more. Cells help us grasp life and death: a living creature is alive, while a dead one is dead.
Therefore, flowers, blood, bacteria and skin all are living things made up of cells.
