If a new species of honeycreeper were discovered, and it had a short, straight beak, which bird in this puzzle would likely be its closest living relative?

Answers

Answer:

The bird species that share the closest phenotypic characteristics are likely closest relatives.

Explanation:

Evolution theory states that species evolve gradually trough mutations (many of them are neutral), thereby those honeycreeper populations closest are more likely to share phenotypic features with each other.

Homeostasis can require the control of many different variables in organisms. Homeostasis regarding internal body temperature is very important for many organisms. How is this different among ectotherms and endotherms?

Answers

Answer:

The term homeostasis refers to balance, where an organism seeks to maintain the balance of the temperature of its organism in order to persist in life.

There are organisms that are considered ectotherms, with which they release heat to the external environment in order to balance said increase in temperature and not denature their own proteins (such as enzymes, structural proteins, receptors, second messengers, etc.). On the other hand, in the case of endotherms, take energy from the medium to increase your body temperature and maintain it, since otherwise you could enter hypothermia.

In the human organism these principles occur both, not simultaneously, but according to the external temperature in which the human is, ectothermic / catabolic processes in heat stages and endothermic or anabolic processes in the cold stage.

Explanation:

In simple words, endotherm is the heat taken from the medium and exotherm or ectotherm is the release of heat to the medium.

This is so simple in objects, but in living organisms these processes have a reason, and that is why we explained above, when looking for a constant temperature these processes are responsible for mediating balance.

Describe the sequence of events during a blood clot.

Answers

Answer: Hemostasis includes three steps that occur in a rapid sequence:

Explanation: 1) vascular spasm, or vasoconstriction, a brief and intense contraction of blood vessels; (2) formation of a platelet plug; and (3) blood clotting or coagulation, which reinforces the platelet plug with fibrin mesh that acts as a glue to hold the clot.

or:

The Blood Clotting Process

Injury. A small tear in a blood vessel wall (for example, from a cut on the skin or an internal injury) causes bleeding.

Vessel constriction. To control blood loss the blood vessel narrows (called constriction), thus limiting blood flow through the vessel.

Platelet plug. ...

Which traits would Aristotle have used to classify sharks? Choose more than one answer.

Answers

Answer:

The main trait that was different between sharks 14 and 9 was that shark 14 (Mobulidae) has a front with two points that look like horns, whereas shark 9 (Dasyatidae) has a front with no points that look like horns.

Explanation:

The traits that Aristotle would have used to classify sharks are :

Front with points ( hornlike )Front without points

Sharks classification

Sharks whose front have two points like horns are classifed by Aristotle as sharks 14 (Mobulidae). whlie sharks whose front does not have two points like horns are classifiesd as sharks 9 ( Dasyatidae ). hence the traits that would have been used by Aristotle to classify sharks is the presence of points at the front.

Hence we can conclude that the traits that Aristotle would have used to classify Sharks are Front with points and front without points.

Geosphere is made up of the crust they form the layer of soil that support growth of plant and also supply nutrients.

Atmosphere is made of gas some of which help sustain life. Example is oxygen, carbon dioxide

Hydrosphere form the liquid portion of the earth it included large water bodies that serves as habitat for aquatic organism.

Oxygen and carbon are been released into the atmosphere where they are been taking up by plant or animal dead and remains of this organism lead to the release of this gases in both organic and in organic form back into the soil where it is taken up by plants back into the atmosphere and some are washed in the water bodies.

Plants takes in carbon-dioxide from atmosphere, absorbs nutrients from the soil through their root and water from the water table needed fro their growth.

I will go with sponges :)

Sponges reproduce asexually. The parent begins budding, when the buds grow to a certain point, they break off and drift with the oceans current to a new place, settle down into the sand or rocks, and start the cycle all over again. Since sponges are stationary organisms (meaning that they cannot travel on their own.) They rely on the oceans current to spread their species across the oceans.

Answer:

Explanation:

Moon jellyfish reproduce during two different stages in their life cycle. During the medusa stage, they reproduce sexually by releasing sperm and eggs into the water. The method of reproduction used by jellyfish polyps is known as budding, and it does look like a plant growing a new bud for a flower. The polyp essentially clones itself. The clone buds out of the original polyp and detaches to float freely in the water.

Describe how C. parvum obtains the glucose it needs for glycolysis after it has infected another cell. Explain the role of lactate dehydrogenase in enabling C. parvum to continue producing ATP by glycolysis.

Answers

Answer:

Cryptosporidium parvum is an apicomplexan pathogen that obtains glucose either directly from its host or by the degradation of polysaccharides.

Explanation:

C. parvum only can produce ATP by glycolysis. Lactate dehydrogenase (LDH) is a universal enzyme required to synthesize pyruvate, which is the final product of the glycolysis process. This enzyme has been subject of research to understand the metabolism and evolution of apicomplexan parasites, including C. parvum.

Cryptosporidium parvum is a pathogenic agent that causes the disease cryptosporidiosis. The pathogen obtains glucose directly from the host. It can also obtain by the breakdown of polysaccharides.

C. parvum produces ATP through glycolysis. The enzyme lactate dehydrogenase is used by the C. parvum to generate metabolic ATP. It generates this ATP through the glycolytic pathway. The enzyme allows the conversion of NADH to NAD+. NAD+ is necessary for glycolysis to produce ATP. Metabolic energy plays a crucial role in the growth and proliferation of the pathogen in the host.

Some of the features of C. parvum are:

It consists of a unique lactate dehydrogenase enzyme to yield ATP. It causes the disease in the gastrointestinal tracts. The pathogen is used for research and understand its ability to obtain ATP directly from the host.

Therefore, C. parvum consists of enzyme lactate dehydrogenase that helps in energy production through the glycolytic pathway.
