B.The long beak helps the bird eat insects.
C.The scarlet ibis is the national bird of Trinidad.
D. The bird's features are red.
Answer: Yup, B should be correct :)
Answer:
B
Explanation:
B is the most "scientific" of the options
1. A new species of multicellular, eukaryotic heterotrophs is discovered. This species secretes digestive enzymes to digest its food externally. Which taxa would this organism belong to?
A.
domain Archaea
B.
phylum Platyhelminthes
C.
kingdom Fungi
D.
kingdom Animalia
2. Mammals and reptiles both belong to the amniote clade. What is the evolutionary significance of this clade?
A.
Amniotes produce membranes that allow them to reproduce without laying eggs in water.
B.
Amniotes produce milk to feed their offspring.
C.
Amniotes were the first vertebrates to evolve limbs specialized for living on land.
D.
Amniotes were the first vertebrates to evolve jaws for digesting the tough food found on land.
3. Which of the following is an example of negative feedback leading to homeostasis?
A.
a sponge conforming its internal salt concentration to match the salinity of its environment
B.
a frog slowing its metabolic rate while hibernating over the winter
C.
a cat’s uterine contractions increasing in strength as it gives birth to a litter of kittens
D.
a human sweating to reduce his or her body temperature on a hot day
2.In the evolutionary process, mammals and reptiles evolve Amniotes produce membranes that allow them to reproduce without laying eggs in water.
What are aminiot animals?Amniote animals are those that have amnion surrounding the embryo, while non-amniotes do not have this membrane.
3.Homeostasis in environments can have as a negative example a sponge conforming its internal salt concentration to match the salinity of its environment.
By saving too much the marine environment limits the lives of other animals causing them to migrate in this way, there will be a collapse in the food chain.

Describe what happens when blood glucose levels are not kept stable.
Blood glucose levels should be kept stable in the body because :-
A rise in glucose level can cause diabetes mellitus or simply diabetes due to too much glucose in the blood stream.In this patients pass urine too much loaded with sugar. Also he feels thirsty due to too much loss of water and becomes weaker and weaker.A fall in glucose level can cause hypoglycemia.
Even a little fall of glucose level in the bloodstream can bring a patient in a state of coma. The person gets frequent headaches, vomiting, dizziness, etc.The regualtion of glucose in the body is done by two main hormones secreted by an endocrine gland called pancreas.
These two hormones are - Insulin and Glucagon.Insulin lowers the glucose level in the body whereas, Glucagon helps in increasing it.Therefore, the glucose level should be always kept stable in the body.

Solution 2
Solution 1
Solution 3
The three types of solutions and concentrations can be classified as:
Solution 1: HypertonicSolution 2: HypotonicSolution 3: IsotonicWhat is the concentration of a solution?The concentration of a solution must be expressed in quantitative units. So-called concentration units are used, which are quantitative measures of the affinity of solute that dissolves. The relative amount of a substance is known as the concentration and is expressed in different units.
In this case we can classify these solutions as :
Hypertonic solution: has higher osmotic pressure and solute concentration.Hypotonic solution: has lower osmotic pressure and solute concentration. Isotonic solution: the solute concentration and osmotic pressure are equal, thus reaching equilibrium.See more about solution at brainly.com/question/7932885

Two cultures, each containing a different species of bacteria, were exposed to the same antibiotic. explain how, after exposure to this antibiotic, the population of one species of bacteria could increase while the other population of the other species of bacteria decreased or was eliminated. *
The antibiotic was effective only against the bacteria species that decreased or was eliminated, but ineffective against the population that increased.
What are antibiotics?
When talking about antibiotics we refer to drugs or medicine used to treat infections caused by bacteria. They act to impede bacteria reproduction and eliminate them.
Antibiotics only act on bacteria, not viruses or other microorganisms, which means that they will only have an effect on affections caused by bacteria.
Also, not any antibiotic can be used to treat any bacterial affection. The antibiotic that must be used depends on the bacteria species. Each bacteria has its own properties, and hence, they respond to different drugs.
Antibiotics are grouped according to their chemical structure, properties, action spectrum, and the type of bacteria they attack.
According to this information, since each antibiotic is effective only against certain bacteria, we could assume that,
the antibiotic used in the experiment did not have any effect on the population of bacteria that could increase
the antibiotic was effective against the other bacteria species, causing its population to decrease or be eliminated.
The antibiotic was effective only against one of the bacteria species -the population that decreased or was eliminated- but ineffective against the other population.

4. Which of the following is a parasite?
(a) Mushroom
(b) Fungi
(c) stem
(c) Cuscuta
(d) haustoria
(d) Rhizobium
Answer:
C: Cuscuta is a parasite .
Explanation:
Mushrooms are a part of the fungi domain meaning that it is a decomposer. I'm not too sure whether it means stem body cells or a stem in a plant. Either way both are not parasites. Cuscuta is a plant that does not have chlorophyll (they can't carry out photosynthesis) and since this plant cannot make its own food, it feeds off a host plant that can make food. An organism that needs a host to survive is called a parasite. Haustoria is a part of some parasites however it itself is not one. And finally Rhizobium is a bacteria that converts Nitrogen into ammonia which helps plants.
