The herbivores in the forest don’t consume this low-growing invasive plant because they mistake it for a similarly shaped toxic plant in the forest. The invasive plant needs a lot of room to grow. It sprouts from its seeds much earlier than the native species. What effect can its growth have on the native herbivores’ food supply?

Answers

Answer:

It could grow at such an extrem erate that it could use up all natural resources that the native species needs to survive. thus breeding out all native species and becoming a invasive species. The native species the animals eat now does not exist and the animals that needed that food will decrease drastically in populus.

b) How does adaptation affect the survival of a species? Why?

Answers

In evolutionary theory, adaptation is the biological mechanism by which organisms adjust to new environments or to changes in their current environment. This enables better survival and reproduction compared with other members of the species, leading to evolution.

When the heart is in fibrillation, A) there is no contraction of the myocardium. B) effective pumping of the ventricles ceases because the myocardial cells fail to work as a team, and the brain cannot get adequate oxygen. C) the myocardial cells may become damaged from contracting too fast. D) the myocardial cells deplete their oxygen supply because they are contracting too fast, and the lactic acid produced damages the myocardial cells. E) the myocardial cells are contracting together as they should; fibrillation indicates a normal sinus rhythm of 75 beats per minute.

Answers

Answer:

The correct answer is - B) effective pumping of the ventricles ceases because the myocardial cells fail to work as a team, and the brain cannot get adequate oxygen.

Explanation:

When the heart is in an irregular and rapid heart rate due to chaotic electrical signals in the atrial chambers of the heart which leads to a very fast heart rhythm that shows 100 to 175 heart rate. That leads to failure of the myocardial cells that stop the pumping of the ventricles effectively and therefore blood would not reach the brain and the brain would not get an adequate amount of oxygen. This will result in organisms experiencing faint, blackout or stroke-like complications.

6. The absorbed dose of electrons is 50 mrad. What is the equivalent dose in J/kg?
O 5.0 x 10-4 g/kg
500 J/kg
5.0 x 10-3 J/kg
50 J/kg

Answers

Answer:

5.0 x 10-4 g/kg

Explanation:

This is because

I mrad is equivalent to 1/100,000j/kg

Therefore,

To convert 50 mrad to j/kg

= 50/100,000

= 5 × 10^-4j/kg.

Millirad is a decimal unit or rad which is the unit for measuring absorbed ionization radiation.

Los órganos análogos pueden ser distinguidos durante desarrollo embrionario ya que ellos experimentan diferentes mecanismos para su formación.

When a person is suddenly cut by a sharp object, a nervous impulse is sent along a sensory neuron to the spinal cord. The impulse is immediately transmitted through motor neurons to produce a response. Which of the following correctly identifies and describes this response?
A.It is a leamed response that does not occur in infants and small children
B. It is a reflex response that causes various muscles to contract in order to move away from the object.
C.It is a conditioned response that occurs only to prevent injury!
D. It is a voluntary response that is initiated only after the impulse has been caried to the relevant area of the brain.​

Answers

Answer:

B. It is a reflex response that causes various muscles to contract in order to move away from the object.

Explanation:

I just took the Test

It is a reflex response that causes various muscles to contract in order to move away from the object. Therefore, option (B) is correct.

What is reflex response?

A reflex response is an automatic, involuntary response to a stimulus that does not involve the conscious part of the brain. In this case, the reflex response causes various muscles to contract in order to move away from the sharp object, which helps to minimize further injury. Reflexes are a protective mechanism that can operate without the need for conscious control or decision making.

The reflex response described in this scenario is not a learned response, a conditioned response, or a voluntary response. It is an innate, automatic response that occurs in response to a specific stimulus, and it occurs in both infants and adults.

Answer:

It may be that synthesis in population dynamics has been slow to emerge because population change is more complicated than it first appears. After all, population change is determined ultimately by only four factors: birth, death, immigration, and emigration.

Explanation:

Research has shown that population size and growth are important factors in the emission of greenhouse gases. ... While population-driven emissions from developed nations are estimated to contribute 42 percent of CO2 emissions between 1985 and 2020, they are expected to contribute only 3 percent between 2025 and 2100.

A pollinator is anything that helps carry pollen from the male part of the flower (stamen) to the female part of the same or another flower (stigma).

Self-pollination is the transfer of pollen from the anther to the stigma of the same flower.

Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different.

A variegated leaf with green and yellow patches is used for an experiment to prove that chlorophyll is required for photosynthesis. Before the experiment the green portions (A), and the yellow portions (B), arte observed. What will be the colour of „A‟ just before and after the starch test? Also write the equation of photosynthesis and mark, well ash molecule the by-product is obtained.

Answers

Answer: The colour of A before the starch test is GREEN while after the starch test is BLUE- BLACK. The equation for photosynthesis is

6CO2 + 6H2O → C6H12O6 + 6O2.

Explanation:

PHOTOSYNTHESIS is the process by which green plants use energy from sunlight to manufacture their own food. It is a building up process since simple inorganic compounds such as carbondioxide and water are built up into large organic compounds such as glucose and OXYGEN is given off as a by product.

Oxygen given out in photosynthesis occurs in the light stage during the process of photolysis of water. This occurs when the chlorophyll traps, absorbs and captures light energy and become energised. The energised chlorophyll supplies energy which is to split molecules of water into hydrogen ion ( H+) and hydroxyl ion ( OH-). The hydroxyl ion is reconverted to water and oxygen is given out as a by product.

To show that chlorophyll is NECESSARY for photosynthesis, a variegated leaf with green and yellow patches is used for an experiment.

The green portion is marked A and the yellow portion marked B. The leaf is tested for starch using the procedure below:

--> place leaf in boiling water for half a minute to kill it.

--> decolorize leaf by placing it in hot alcohol.

--> dip decolorize leaf in hot water to soften it.

--> place leaf on tile and add iodine solution to it.

RESULT: It would be found that only the green parts contain starch as blue+black colouration is observed while yellow area is unaffected by iodine.

Cells are the structural and functioning units of all living organism. They formed the foundation all living organism.

Based on location and functions, there  are different types of cells. Because some cells transfer messages from one part of the body to another, they are have a head like structure(the cell body) and a  a long pipe shaped structure (axon) and with branches at the end ( dendrites) .These cells are nerve cells. They are located in the CNS  and PNS.

Other cells on animals have almost the same shape with some variations.

Similarities.

Both contains Nucleus, mitochondria

Both contains fluid inclusion called cytoplasm where all organelles,

Both bounded  layer of cell membranes to restrict movement  the cells organelles and to give shapes.

Differences;

Typical animals cells are of different colors based on location in organs .But

nerve cells  are made of the grey color ( granules) of the cell body and white color of the axon. This is uniform for all nerve cells.

Animal cells performs different functions in animals based on location, but nerve cell is for transmission of impulses and action potential only.

Animal cells undergo regeneration after death or damage. The Regeneration of  nerve cells is slow or not possible in most cases. This is the reasons why most neurological disease are incurable.

Animal cells are made up of three distinct parts: the cell membrane, cytoplasm and the nucleus. Cell body, axon and dendrite are the parts of a nerve cells.
