Describe sea turtle populations during the late 1400’s
Answer:
6.5 million sea turtles
Recent estimates show us that there are nearly 6.5 million sea turtles left in the wild with very different numbers for each species, e.g. population estimates for the critically endangered hawksbill turtle range from 83,000 to possibly only 57,000 individuals left worldwide.

explanation for the DNA found in
mitochondria?
A. Mitochondria was once a prokaryotic
organism.
B. Mitochondria was once a eukaryotic
organism.
C. Mitochondria was once a primkaryotic
organism.
Answer:
A
Explanation:
its a
The most likely explanation here is that mitochondria was once a prokaryotic organism. The correct option is A.
What is mitochondria?Mitochondria are membrane-bound cell organelles that produce the majority of the chemical energy required to power the cell's biochemical reactions (mitochondrion, singular).
The mitochondrial energy is stored in a small molecule known as adenosine triphosphate (ATP).
Mitochondria are special compartments (organelles) in our cells best known for their role as powerhouses, converting food molecules into ATP, a molecular fuel for the rest of the cell.
Mitochondria and chloroplasts most likely evolved from engulfed prokaryotes that were once self-contained organisms.
At certain point, an aerobic prokaryote was engulfed by a eukaryotic cell, which then formed an endosymbiotic relationship with the host eukaryote, eventually developing into a mitochondrion.
Thus, the correct option is A.

Determine the new concentration, in mg/mL, of the starch solution you diluted in the Erlenmeyer flask. Recall from the Procedures that there are 20 mg/mL of starch in the 2% solution. Use that to determine the milligrams of starch in the diluted starch solution. Then, divide the milligrams of starch by the total volume of the solution, which includes the water plus the starch solution. Record your results for use in future questions.
a. 2 mg/mL
b. 0.05 mg/mL
c. 0.2 mg/mL
d. 10 mg/mL
Answer:
0.05 mg/mL ( B )
Explanation:
Given data:
20 mg/ml starch
2% solution = 2g of solute is in 100g of solvent
Determine the new concentration in mg/ml
Dilution equation = C1V1 = C2V2
new concentration ; applying the dilution factor
dilution factor = 1 : 400 ; ( 2 /400 )g = 0.005 g of solute is present in every 100 mL
∴ new concentration = 0.00005 g / 1 mL * ( 1000 mg / 1g ) = 0.05 mg/mL
What would happen to the weight of an ice cub if it melted?
A) it would weigh a little more.
B) it would weigh a lot less.
C) it would weigh the same.
D) it would weigh a lot more.
Answer:
C. it would weigh the same
Explanation:
The mass of the ice doesn't change as the ice melts, so the volume displaced remains the same whether its is solid or liquid.
Her eyes are wide-set and slightly slanted. Her nose is short and flat, and she keeps her mouth slightly open. There is a straight crease across her palm, and her fifth digit is unusually short. The doctor tells her parents she has an inherited disorder. If you were the doctor what would you diagnosis Kate with? Discuss the etiology of Kate’s disorder? What is the biggest risk factor for this disorder? How can or will this disorder affect Kate? What test could have been completed to diagnosis this disorder before Kate’s birth?
Answer:
- These morphological features belong to Down syndrome.
- Diagnosis: Down syndrome (Trisomy Extra chromosome 21).
- Etiology: the presence of three copies of the autosomal chromosome 21 instead of two copies in body (somatic) cells.
- Most important health problem: Down syndrome increases the risk of developing Alzheimer's disease (other health problems include heart congenital defects, vision problems, hearing loss, hypothyroidism)
- Diagnostic test: Amniocentesis
Explanation:
Down syndrome (DS) is the most frequent chromosomal abnormality which is generally caused by the presence of an extra copy of autosomal chromosome 21, thereby it is an autosomal trisomy (trisomy 21). DS is often associated with intellectual disability and increased risk of developing Alzheimer's, as well as health problems including, among others, heart congenital defects, vision problems, hypothyroidism, blood disorders, hypotonia, endocrine problems, dental problems, seizures, etc. Amniocentesis is the most common invasive prenatal diagnostic procedure which is used to identify chromosomal abnormalities such as trisomy 21 (Down syndrome). Amniocentesis is done between 15 weeks and 20 weeks of pregnancy.

Explanation:

What is conjugation?During bacterial conjugation, genetic material is transferred from one bacterial cell to another through a structure called a pilus (plural: pili). Pili are thin, hair-like projections that extend from the surface of the bacterial cell and are used for a variety of purposes, including adherence to surfaces and transfer of genetic material. When two bacterial cells are in close proximity to one another, one of the cells can extend a pilus towards the other cell.
The pilus will then make contact with the recipient cell and transfer a small piece of DNA, known as a plasmid, across the intercellular space. This process allows bacteria to exchange genetic material, which can lead to the acquisition of new traits and the spread of antibiotic resistance. Capsules, cell walls, and the surrounding medium are not involved in the transfer of genetic material during bacterial conjugation.

Which best describes adenosine triphosphate (ATP)?
A waste product molecule that is produced by cells but cannot be used by them.
A high energy molecule that is used by every cell in the body as an energy carrier.
A process that is used to create energy when oxygen is available to the body.
A process that is used to create energy when oxygen is not available to the body.
Answer:
a high-energy molecule that is used by every cell in the body as an energy carrier.
Answer:
A high energy molecule that is used by every cell in the body as an energy carrier.
Explanation:
Adenosine triphosphate, also known as the "energy currency" of the cell is an organic molecule that readily supplies energy to the cells to carry out metabolic and catabolic functions. This molecule consists of a nitrogenous base known as adenine, ribose sugar, and three phosphate molecules. The hydrolysis of ATP provides energy for muscle contraction, nerve impulses, signaling for hereditary materials like DNA and RNA, as well as phosphorylation.

What is the difference between the rough and smooth endoplasmic reticulum?
Answer & Explanation:
The most basic difference between RER and SER is the presence of ribosomes. When ribosomes attach to the surface of an ER, it gives a characteristic rough appearance; hence it is called Rough ER. On the other hand, a smooth ER does not have ribosomes on its surface. It possesses ribosomes attached to its membrane.

DDT is an insecticide that accumulates in the fatty tissues of animals whose concentration increases with each link of the food chain. Which group of organisms is most likely to accumulate the highest concentration of DDT?
The question is incomplete, the complete question is shown in the image attached
Answer:
D
Explanation:
Pollutants tend to an increase in concentration in the fatty tissues of animals compared to the concentration of the same pollutant in the environment.
Also, tend to increase in the fatty tissues of organisms at each trophic level.
Hence, as a result of this, the highest concentration of the insecticide is accumulated by the organisms at the highest level of the food chain. So, the tertiary consumers accumulate the highest concentration of the insecticide.
