Bats Devastated by Deadly FungusThe most common bat species in North America, the little brown bat, could be facing extinction because of a fungus. The fungus, called white-nose syndrome, grows on the exposed skin of bats as they hibernate in cool caves or mines. Infected bats develop lesions (sores) on their wings, which play important roles in water balance, circulation and heat regulation. These lesions on a bat’s wings or on its nose cause the bat to wake up during hibernation. Waking up early forces the bat to use up the energy it has stored as fat for its long sleep, exhausting the animal and eventually killing it. In some infected caves, 90 percent to 100 percent of bats die. On average, the disease takes out 73 percent of the bat population at a given hibernation site. If infection continues at current rates, the researchers predict that the little brown bat population will drop below 0.01 percent of its current numbers by 2026. The loss of the little brown bat would be harmful for humans because bats eat their body weight in insects each night. Many of these bugs are agricultural pests or carriers of human disease. One way to decrease the spread of the disease would be for the researchers who visit infected caves to decontaminate their clothes and gear with antiseptics. It has also been suggested that a small number of these bats could be placed in an artificial hibernating area and medicated to protect them. Describe one way that an infection with the white-nose fungus can cause death in little brown bats.

Which of the following ligaments is a cylindrical band that connects the ovary to the uterus?A) Round ligament
B) Broad ligament
C) Suspensory ligament
D) Ovarian ligament

Answers

Answer:

D) Ovarian ligament

The ligament that connects the ovary to the uterus is called the ovarian ligament.

Explanation:

The ovarian ligament is attached to the ovary inferiorly. It connects the ovary to the side of the uterus. Structurally, it is a fibrous band of tissue that lies within the broad ligament.

Final answer:

The Ovarian ligament is the cylindrical band that connects the ovary to the uterus. Other ligaments like the Round ligament, Broad ligament, and Suspensory ligament have other roles within the female reproductive system.

Explanation:

The ligament that connects the ovary to the uterus in a cylindrical band is the Ovarian ligament (option D). The ovarian ligament is a fibrous cord that connects the ovary to the lateral surface of the uterus. This plays an important role in the female reproductive system by helping to keep the ovary in place.

Just to clarify further, the Round ligament is a ligament that connects the front of the uterus to the groin area; the Broad ligament is a broad fold of peritoneum that envelops the uterus, associated structures, and adjacent parts of the abdominal wall; the Suspensory ligament is a peritoneal ligament extending from the hilum of the ovary to the wall of the pelvis and contains the ovarian vessels.

According to cell theory, all cells carry out the functions needed to sustain life. That means all cells must contain A) DNA. B) a nucleus. C) organelles. D) a control center.

Answers

According to cell theory, all cells carry out the function needed to sustain life.It means all cells must contain DNA  as it is a molecule that holds biological instructions to develop, survive, and reproduce.

Thus, option A is correct.

What is cell theory?

  • Cell theory is given by Robert Hooke.
  • According to cell theory all cells arise from already existing cell
  • Cell is the basic structural and functional unit of life
  • All living organisms are made up of cell either single or multi cell

DNA is deoxyribonucleic acid made up of two polynucleotide chains that arranged in a double helical structure.

The main functions of DNA are replication, uncoding  information,recombination and gene expression.

DNA plays a vital role and it is considered as primary unit of heredity in all types of organisms.

Therefore,According to cell theory, all cells carry out the function needed to sustain life.It means all cells must contain DNA  as it is a molecule that holds biological instructions to develop, survive, and reproduce.

Thus, option A is correct.

Process that takes place at mid-ocean ridgesA. Sea-floor spreading

B. Continental drift

C. Magnetic reversal

D. Magnetic minerals

E. Fossils

Answers

Answer;

-Sea-floor spreading

Sea floor spreading is process that takes place at mid-ocean ridges, evidence is found in magnetic minerals on the ocean floor.

Explanation;

-Seafloor spreading is a geologic process in which tectonic plates; large slabs of Earth's lithosphere; split apart from each other.

-Seafloor spreading and other tectonic activity processes are the result of mantle convection. Mantle convection is the slow, churning motion of Earth’s mantle. Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle’s convection currents makes the crust more plastic and less dense.
a. sea-floor spreading

What are three different defects that could be responsible for malfunctioning lysosomes?Select the three correct answers.
A) a defect in the synthesis of the glucose-6-phosphate dehydrogenase
B) a defect in the mannose-6-phosphate receptor in the Golgi apparatus
C) a defect in the releasing small molecules from digested materials into the cytosol
D) a defect in a hydrolytic enzyme that breaks down polysaccharide
E) a defect in the process of adding a mannose-6-phosphate signal to lysosomal hydrolases
F) a defect in the mannose-6-phosphate receptor in the mitochondria

Answers

Thank you for posting your question here. I believe the answer is the below:

B) a defect in the mannose-6-phosphate receptor in the Golgi apparatus
D) a defect in a hydrolytic enzyme that breaks down polysaccharide
F) a defect in the mannose-6-phosphate receptor in the mitochondria

Answer:

B); D) and E)

Explanation:

B) a defect in the mannose-6-phosphate receptor in the Golgi apparatus.

Explanation: The mannose-6-phosphate receptors (MPR's) in the Golgi apparatus are essential for targeting the mannose-6-phosphate tagged lysosomal proteins to the lysosome.

D) a defect in a hydrolytic enzyme that breaks down polysaccharide.

Explanation: Lysosomes contain enzymes that hydrolyze polysaccharides, therefore any defects in these enzymes causes malfunctioning of the lysosome.

E) a defect in the process of adding a mannose-6-phosphate signal to lysosomal hydrolases.

Explanation: In the Golgi apparatus lysosomal proteins are tagged with mannose-6-phosphate so that they are specifically transported to the lysosomes.  

How are autosomal traits, including recessive genetic disorders that are carried in a population, related to Mendel's observations of heredity?

Answers

The expression of the alleles is independent of the organism's sex; both males and females express the allele.
The alleles are not expressed on the basis of sex, that is, in sex-linked fashion. Both male and the female express the traits.
