Suppose the femur bone of an animal has 1,000 atoms of carbon-14 when the animal dies. How many atoms of carbon 14 will be present after 6,000 years? (1 point)
Answer:
After 6000 years, approximately 500 atoms of carbon-14 will be left in the femur bone of an animal which had 1000 atoms of carbon-14 when the animal died.
Explanation:
The half-life of a radioactive isotope of an element is the time taken for half the atoms present in a given amount of the element to undergo decay or disintegration. For example, the half-life of carbon-14 isotope is 5730 years. This means that, if there are 100 atoms of carbon-14 present in a given sample of a material, in the next 5730 years, approximately, 50 atoms of carbon-14 will be left in the material.
Since the half-life of radioactive isotopes are constant, these radioactive isotopes are used in the determining the ages of ancient life-forms as well as rocks.
In the given example, after 6000 years, approximately 500 atoms of carbon-14 will be left in the femur bone of an animal which had 1000 atoms of carbon-14 when the animal died.
Which statement best describes genetic material?
Answer:
Genetic material, including genes and DNA, controls the development, maintenance and reproduction of organisms. Genetic information is passed from generation to generation through inherited units of chemical information (in most cases, genes).
Explanation:
I hope this answer help you
Genetic material controls organism development, maintenance, and reproduction. Chemical units carry genetic information from generation to generation. Therefore, (B) is correct.
What is genetic material?The component of the cell that stores the information that can be passed down from generation to generation is referred to as the genetic material. The information that the cell needs in order to build proteins is stored in the genetic material, which is the genetic material's most significant function.
The development, maintenance, and reproduction of organisms are all under the control of their genetic material, which includes genes and DNA. The information contained in a person's genes is handed down from one generation to the next in the form of inherited units of chemical information.
Therefore, option (B) is correct because genes are sections of the genetic material known as deoxyribonucleic acid (DNA), which contain the instructions for making a particular protein.

is the penguin a bird?? please help
<3
Answer:
Yes, it is.
Explanation:
Penguins are a species of seabird that lives in the southern hemisphere, in areas close to Antarctica, characterized by its cold and wide expanses of sea without land. In this context, penguins are capable of living in these temperatures and feeding on fish and other marine elements. In addition, they are unable to fly, but not so to move through the sea using their wings for it.

In the year 2374, humans finally developed the technology necessary for time travel. You are a scientist interested in the population genetics of extinct animals. After seeing Jurassic World, you decide to go back in time to study a population of velociraptors. The skin color of this dinosaur varies between tan (dominant) and brown (recessive). You observed 336 tan velociraptors and 64 brown velociraptors during your study. Assume the population is in Hardy-Weinberg equilibrium. a) What is the allelic frequency of the dominant (tan) allele in the population
Answer:
The allelic frequency of the dominant (tan) allele in the population equals 0.6

Which of the following blood vessels would have the highest blood pressure?
A dilated vessel with high blood volume
A constricted vessel with high blood volume
A dilated vessel with low blood volume
A constricted vessel with low blood volume
Answer:
a constricted vessel with high blood volume
Explanation:
because the size or area within affected blood vessels is reduced by vasoconstriction. Therefore, the blood flow is often decreased as blood vessel pressure is lower. The pressure or power of blood flow is increased at the same time, which results in higher blood pressure is the force exerted by this.

where is the equator of a cell
Answer:
Where the cell divides
Explanation:
I think the equator, or equatorial plate, is the midline of the cell where duplicated chromosomes position during mitosis.
The equator of a cell is where equator divides.
Cell:
Cell is the basic unit of life. There are two types of cell : prokaryotic cell and eukaryotic cell. Cell divides by the process of mitosis and meiosis. Mitosis is an equational division and meiosis is reductional division.
Cell division is important for cell growth and division. Cell division starts at the nucleus. In nucleus there are different chromatin material. Chromatin condensed and form a chromosome.
Cell division starts at the equator of the cell. There are four phases : Prophase, metaphase, anaphase and telophase. During metaphase all the chromosome align at the equator.
Therefore, The equator of a cell is where equator divides.

Explanation:
Highly sensitive cells within the hypothalamus that react to changes in blood composition and cause the release of antidiuretic hormone (ADH) when appropriate are called.
Answer:
osmoreceptors
Explanation:
Osmoreceptors are nerve cells (neurons) capable of detecting changes in the extracellular fluid (ECF) osmolality, i.e., in the amount of solute in free water within the ECF. Osmoreceptors are known to contribute to osmoregulation by controlling body-fluid balance. These sensory receptors are mainly localized in the hypothalamus of homeothermic animals where they detect variations in the osmotic pressure and stimulate the release of antidiuretic hormone (ADH) in blood in response to the increase in plasma osmolality.

5. Which describes the variable that is changed to test the prediction?
experimental
control
dependent
independent
Answer:
Independent
Explanation:
An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).
This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.
In an experiment , the variable being manipulated by an experimenter is known as an independent variable while the dependent variable is the event expected to change when the independent variable is manipulated.
Hence, independent variable describes the variable that is changed to test the prediction.

Drosophila geneticists have isolated many mutations that modify position-effect variegation. Dominant suppressors of variegation [Su(var)s] cause less fre- quent inactivation of genes brought near heterochro- matin by chromosome rearrangements, while dominant enhancers of variegation [E(var)s] cause more frequent inactivation of such genes.
A. What effects would each of these two kinds of mutations have on position-effect variegation of the white gene in Drosophila (that is, would the eyes be more red or more white)?
B. Assuming that these Su(var) and E(var) mutations are loss-of-function (null) alleles in the corresponding genes, what kinds of proteins do you think these genes encode?
Answer:
A. As it is given that Su(var) dominant suppressors of variegation mutant allele causes lesser white patches and more red patches in eyes as it is an inhibits or inactivates of PEV. If the Drosophila were heterozygous for the dominant enhancers of variegation E(var) mutation, there would be less red patches and more white patches.
b. Su(var) 1 gene encodes for the proteins that assist in the spreading of heterochromatin by inhibits the PEV which will be lost by null mutations while E(var)1 gene encodes for the proteins that restrict the spreading of heterochromatin by loss of function mutation
