why do sporangiophores grow vertically whereas rhizoids grow downwards
Answer:
The sporangiophore grow vertically which is in an upward direction because it is positively phototrophic. This means that it grows towards the ray of light from the sun which is found above. This is usually due to the provision of solar(light) energy from the sun which is used for the photosynthetic processes of the plants
The rhizoides grow downwards because they are positively geotrophic. This means they grow according to the force of gravity which acts downwards.
Which forms of muscular dystrophy are X-linked? a. Becker b. Duchenne c. Facioscapulohumeral d. A combination of Becker and Duchenne"
Answer:
The correct answers a and b.
The inheritance of Becker and Duchenne dystrophies are linked to the X chromosome.
Explanation:
Duchenne and Becker muscular dystrophies (DMD and BMD, respectively) are neuromuscular diseases characterized by progressive muscle atrophy and weakness, as a consequence of the degeneration of skeletal, smooth and cardiac muscles. Both muscular dystrophies are caused by mutations in the DMD gene, located on the X chromosome. This is the largest known human gene and it encodes a protein called dystrophin, which is expressed in muscle cells. The mutations responsible for DMD lead to a total absence of dystrophin, while those underlying DMB lead to an abnormal quantity and / or quality of the protein. In both cases it is common to find deletions of the gene.

An engineer wants to build a house on a beach. Buildings on the shore must be built high enough to avoid flooding from oceans during storms. The highest wave height elevation measured for storms in the area is 15 feet. The support beams must reach a depth of 7 feet underground. Based on scientific knowledge, which of these support beams would be the best to use for the building?
Answer:
Answer B
Explanation:
Because i got it correct
Answer:
Support Beams 25 feet or greater
Explanation:
Not only is this the common sense game but the highest wave height is 15 feet, because the beams must reach a depth of 7 feet underground.
15+7 = 22 feet
To avoid the highest wave it must be at least 22 feet.

Monosaccharides (simple sugars) are also called carbohydrates. Using what you have noticed and learned about the elements in monosaccharides and ratios of the elements, explain why the term carbohydrate is an appropriate term for this group of compounds.
Answer:
Carbohydrate is one of major macromolecule and nutrient that is required for the energy and structure of body of almost every organism. These contains three elements that are carbon, hydrogen and oxygen in the ratio of 1:2:1. The general formula of carbohydrates is Cm(H20)n, in complex sugars m and n can be different.
Monosaccharides are simple sugars basic unit of disaccharides and polysaccharides. the ratio of carbon, hydrogen and oxygen are 1:2:1. As chemical level, they contain carbon, hydrogen and oxygen so termed as carbohydrates.
Which statement best describes both insulin and glucagon? They both provide structural support, but only insulin is a carbohydrate. They both store energy, but only glucagon is a carbohydrate. They are both hormones that regulate blood-sugar levels. They are both hormones that help fight disease.
Answer:
They are both hormones that regulate blood-sugar levels
Explanation:
Insulin is a hormone that controls the blood glucose level. It released in the blood stream when the glucose level increases after eating food. It is produces by pancreas, insulin helps the glucose to enter the body's cells where it can either be stored for future use or can be used for energy.
Glcogen is produced by alpha cells of pancreas, it is a peptide hormone. Its main function is to raise the concentration of fatty acids and glucose in the bloodstream. It is one of the main catabolic hormone of the body
As per the above mentioned statements, the option 'They are both hormones that regulate blood-sugar levels' is the correct answer.

Which category of signal exerts its effects on target cells by binding to membrane-bound receptor proteins
Answer: Neurohormones
Explanation:
Neurohormones are chemicals produced by neuroendocrine cells which behave like hormones. They are released into the bloodstream unlike neurotransmitters that are released into the synaptic cleft.
The same neurohorome can have both functions (hormonal and neurotransmitter). Hormones are chemicals produced by the endocrine glands that move through the body in the bloodstream. They control many biological processes, including muscle growth, heart rate, hunger, and the menstrual cycle. A neurotransmitter is a biomolecule that enables neurotransmission, i.e. the transmission of information from one neuron (a type of cell in the nervous system) to another neuron, a muscle cell or a gland, via the synapse that separates them. The neurotransmitter is released from the synaptic vesicles at the end of the presynaptic neuron, towards the synapse, through the synaptic space and acts on the specific cell receptors of the target cell.
So, a neurohormone is a biomolecule that, like the neurotransmitter and the hormone, is responsible for an exchange of information between cells. The neuroendocrine cells that secretes de neurohormones are, in turn, half neurons, half endocrines, and are found both in the Nervous System and in other parts of the body. They bind to receptors located on the membranes of other cells. Unlike neurotransmitters that interact only with other neurons, neurohormones also interact with other cells. When a neurohormone enters a cell and binds to its receptor, it causes the receptor to change shape, allowing the neurohormone-receptor complex to enter the nucleus and regulate gene activity. The binding exposes regions of the receptor that can bind to specific DNA sequences. These sequences are found next to certain genes in the cell's DNA, and when the receptor binds to them, it alters their transcription levels.
The most obvious case is catecholamines, formed in the adrenal glands by chromaffin cells, which are modified neurons and they are released directly into the blood. In turn, they are also produced by neurons and act at the synapses.

Three species of lizard, labeled A, B, and C, are being studied using molecular analysis by two research colleagues in different laboratories. The mitochondrial DNA of lizards A and B are compared and are found to differ by 0.1%. The ribosomal RNA of lizards B and C are found to differ by 0.02%. They compare their findings and conclude that lizard B is more closely related to C than to A. What is the flaw in their reasoning, and how can their analysis be improved?
A.They applied different mathematical formulas for their computations. They should recalculate using the same formulas.
B'They compared different molecules which have different mutation rates. They should compare same molecule in the lizards.
C.They only made one measurement each. They should repeat their measurements to reduce the uncertainty in their results.
D.They used different equipment for analyzing the molecules since they work in different labs. They should work in the same lab.
Answer:
The correct option is B
Explanation:
The biomolecule used in comparing lizards A and B is the mitochondrial DNA while that used to compare the same lizard B to another lizard C is the ribosomal RNA (rRNA). They should have compared the same biomolecules throughout by extracting the mitochondrial DNA of the three lizards and then proceed to sequence the whole genome of the lizards. After which they can now do a Global alignment (comparison) of the three sequences together. This procedure would have given them a more accurate information on there identity and similarity.

What is the cause of the hydranencephaly? Select one: a. Aqueductal stenosis b. Subaranchoid stenosis c. Overproduction of CSF d. Internal carotid arteries blockage
Answer:
The correct answer is d.
Explanation:
Hydranencephaly is a rare congenital anomaly characterized by the absence and replacement of the cerebral hemispheres by cerebrospinal fluid and necrotic remains, with preservation of the membranes (leptomeninges), within a skull of normal capacity and shape. It is the most severe form of cortical destruction cerebral bilateral and is considered an extreme form of porencephaly (focal cystic cavity). It mainly affects the territory of the internal carotid artery and middle cerebral artery, with preservation of the territories supplied by the vertebrobasilar arteries. The most accepted etiology is carotid vascular insufficiency, due to multiple causes (bleeding, placental thromboembolism, arteritis, vascular malformations, among others).

Question 6 of 10
A scientist bred fruit flies in two separate containers with different food
sources for many generations. When she put the fruit flies from the two
containers together again, she observed that the flies preferred mates raised
on the same food. Which conclusion can the scientist draw?
A. Fruit flies prefer the container where they were bred.
B. Fruit flies mate randomly regardless of how they were bred.
Ο Ο Ο
C. Fruit flies can adapt to eating different food sources.
D. Fruit flies prefer mates adapted to the same food source.
SUBMIT
Answer:
D. Fruit flies prefer mates adapted to the same food source.
Explanation:
Food and diet varies depending on the location of an animal, that being said, it is in the nature of an animal to mate with another in order to produce offspring who can survive on the same food source. Instinctively, a fly would see a mate who's diet differed and think that their offspring would not be able to survive due to the lack of that varying food source.
