Answer: B. They are located and bind the steroids in the cytoplasm
Explanation: Steroid hormones are a class of organic compounds, typically lipids. They bind to protein receptors in the cytoplasm or nucleus of the target cell and thus, their receptors are located inside target cells where they function as ligand-dependent transcription factors. This is to say that hormone-receptor complex formed on binding to DNA activates specific genes that increases production of proteins.
Which of the three traits considered in this film (bipedality, extensive tool use, and large brains) were present in the 3.2-million-year-old Australopithecus fossil (Lucy)?A. Lucy was a bipedal hominid with a brain size similar to that of modern humans, demonstrating that bipedality and larger brains evolved together.B. Stone tools were found in the same rock layer where Lucy was found, showing that members of this species were making and using tools 3.2 million years ago.C. Lucy was a bipedal hominid, and its discover provided evidence that bipedality preceded the evolution of a larger brain size and extensive tool use.D. Lucy had a large brain, but there is no evidence that it used tools or that it walked mostly on two legs.
Answer:
I think the answer is C
Explanation:
C
Lucy was a bipedal hominid, and her discovery provided evidence that bipedality preceded the evolution of larger brain size and extensive tool use.
How important is Lucy's discovery?It is one of the most complete fossils ever found. Because it is a very complete skeleton, compared to the fragments that are usually found, Lucy allowed scientists to better understand human ancestors and study size, shape and locomotion.
Whit this information, we can conclude that Lucy was a bipedal hominid, and her discovery provided evidence that bipedality preceded the evolution of larger brain size and extensive tool use.

Q1. Of which wavelength of light do carotenoids absorb the greatest percentage?
a)400nm
b)500nm
c)600nm
d)700nm
Answer:
B. it's between 460 and 550 nm which would put 500 almost directly in the middle
Explanation:
The wavelength of light which carotenoids absorb the greatest percentage is:
B)500nmA wavelength of light is the visible light which the human eye can see. These have different wavelengths of which some are longer than the others, such as the infrared and the ultraviolet rays
A carotenoid is a type of pigment which are yellowish, orange and red and occurs in plants and algae.
As a result of this, we can see that a wavelength of light which carotenoids absorb the greatest percentage is anywhere between 460-550 nM which would fall under the range of option B
Therefore, the correct answer is option B

Analyze the diagram below. What process is shown?
A. Facilitated diffusion
B. Osmosis
C. Active transport
D. Endocytosis
The transport that is involved in the transportation of molecules through the transport channels called as carrier proteins or transport channels.
What is the diffusion ?
Diffusion is the movement of particles from higher concentration to the lower concentration.
“Active Transport is as process that involves movement of molecules from an area of lower concentration to an area of higher concentration against a concentration gradient or an obstacle with the help of external energy.”
1. Antiport Pumps.
2. Symport Pumps.
3. Endocytosis.
4. Exocytosis
These are the channels that are involved in the process of the active transport. Energy driven process is the process where the proteins are transported into the channels via the transporters. The transporters are the kind of the molecules that transport the molecules through the channels.
Active transport is the process that involves the use of ATP for the transport and the molecules are transported via the expenditure of energy through the ATP usage.

ASAP PLZ Leon is a family doctor. in which economic sector does he work. a. Primary d. Secondary c. Tertiary d. Quaternary
Answer:
Leon's economic activity, being a family doctor, belongs to the tertiary sector of the economy (option c).
Explanation:
Professional services, such as engineers, teachers, lawyers and doctors, among others, belong to the tertiary economic sector, or services. All financial, commercial, educational, health, recreation, transportation, etc. services also belong to this economic sector.
Economic sectors are a set of activities on which the economy of a country is based, involving the flow of money and the exchange of goods and services for currency.
The economic sectors range from the exploitation of natural resources, through industrialization, to the services necessary for the development of individual, family and community life.
The other options are not correct because_
a. Primary sector is based on the exploitation of natural resources and agricultural and livestock production.
b. Secondary sector is where all the activities of industrialization, processing of natural products and manufacturing are located.
d. Quaternary sector is derived from the tertiary sector and consists of the commercialization of intangible goods, such as knowledge. Doctors do not enter this sector because part of their activity involves contact with people and performance of procedures.

A group of people have white blood cell (WBC) counts that are from 4,500 to 10,000 WBC/ml. All cell count values in that range are equally abundant in the population. What is the mean WBC count in the population?
Answer:
7250 WBC/ml
Explanation:
The mean of any value is the average of a certain amount of given values. When this is taken into cognizance, to get the mean White Blood Cell count of the population, given two ranges, is to add and divide both together. This gives us
10,000 + 4,500 = 14,500 WBC/ml
The mean then is
14,500 / 2 = 7250 WBC/ml
Therefore, the mean White Blood Cell count in the population is 7250 WBC/ml

Which of the following base pair sequences could be produced in DNA replication?
AGTCAT
TCAGTA
AGTCUT
TCUGIA
AGTCAT
UCAGUA
AGTCAT
CTGACG
The base pair sequence that could be produced in DNA replication is AGTCAT, UCAGUA. The correct option is c.
What are DNA sequences?The DNA sequence is the sequence or pairing of DNA bases. RNA and DNA both are genetic materials and both are made up of nucleic acids made up of deoxyribose acid and iron is made up of ribonucleic acid.
DNA and RNA both contain four bases that are joined with hydrogen bond RNA contain uracil in the place of thymine and DNA contain timing all other bases are same.
The base pairs are complementary to each other: Thymine: Adenine and cytosine: guanine.
But in RNA, it is uracil with adenine. Guanine and cytosine are the same. So the adjacent base pairs will be:
AGTCAT
UCAGUA

Rhonda visits her MD because she is feeling constantly tired. After a thorough case
history involving questions about her diet, her MD takes a blood sample. Results
indicate that her hemoglobin level is at 7g/100ml of blood (normal levels are 12-
18g/100ml of blood).
Based on the results of Rhonda's bloodwork:
a) What condition might Rhonda have ?
b) Why would Rhonda's low hemoglobin level cause her to feel tired ?
c) Rhonda's MD asked about iron intake (eg. from meat) in her diet? Explain why.
Answer:
a) Rhonda might have anemia
b) Rhonda feels tired because her blood is unable to transport enough oxygen
c) Iron is required by the blood cells for the formation of hemoglobin
Explanation:
a. A low hemoglobin level is referred to as anemia or low red blood count. From her blood test results, Rhonda has below normal levels of hemoglobin. This indicates she might have anemia.
b) The primary work of hemoglobin in blood is to transport oxygen from the lungs to the cells that need it for metabolic activities. When the ability of the blood to transport blood is impaired due to low hemoglobin levels, fatigue and tiredness sets in since enough oxygen is not present for cellular respiration and production of ATP.
c) Hemoglobin is an iron-rich protein that helps red blood cells carry oxygen from the lungs to the rest of the body. If iron intake is not sufficient, anemia could result. Therefore, it is important that iron-rich meals are incorporated into our diet.
So her MD would need to know how much of iron she has been having in her diet.
