Prokaryotes and eukaryotes differ in the presence of the nucleus and the organelles. Prokaryotes are small in size and can easily reproduce and adapt.
What are prokaryotes?Prokaryotes are primitive simple cells that are characterized by single cells with no distinct nucleus and membrane-bounded organelles. Cyanobacteria and bacteria are examples of prokaryotes.
The simple structure of the prokaryotes makes them adapt to environmental changes faster than the complex eukaryotic cell. They have a quick reproduction rate and short life cycles, unlike plants and animals.
The simple and small system of the prokaryotic cell allows the movement and diffusion of the ions and molecules easily. They are extremophiles and can survive harsh environments.
Therefore, small and simple prokaryotic cells are advantageous over eukaryotic cells.

What does band mean in Edwin Drake’s lucky strike
Answer:
Edwin Drake was the first person to strike oil in America. His world-famous well was drilled in Titusville, PA, a small town in Crawford Count
Answer:
Drake met stockholders of the Pennsylvania Rock Oil Company, which claimed a lease on land near Titusville, Pennsylvania, where oil had been gathered from ground-level seepages for medicinal uses. The company hoped to make money selling the oil for lighting, and to this end the stockholders sent Drake to Titusville to assess the viability of the enterprise. Letters of introduction to businessmen in the area referred to Drake as “Colonel,” and for the rest of his life he was known as Colonel Drake. After Drake returned to New Haven with a favourable report, the New Haven stockholders formed a new company, the Seneca Oil Company, sold some stock to Drake, and sent him back to develop the site.

A person holds a bow and arrow with the arrow pulled back.
Which will most likely increase the kinetic energy in this system?
pulling farther back on the string
releasing the string
holding the arrow higher
decreasing the mass of the arrowm
Answer:
pulling further back on the string
Explanation:
I chose that because as for me answer 2 and 3 don't make sense but as for answer four I don't think that when you decrease the mass of the arrow this will increase the kinetic energy because for it to move faster I'll have to pull the string harder or to enlarge it ,so to increase the kinetic energy it is just determined by how I pull that string ."have I enlarged it or it is still loose."

How could a doctor test someone for hyperglycemia?
a) Do a cardiac stress test.
b) Check the urine for glucose.
c) Check the blood for sodium.
d) Check the platelet count with a blood draw.
Answer:
the answer is b check the urine for glucose
Hyperglycemia, otherwise known as high blood sugar, can be diagnosed with a blood test such as a fasting plasma glucose (FPG) test, an A1C test, or a fructosamine test. Additionally, hyperglycemia can be identified using a glucose monitor or by drinking a beverage and monitoring the body's glucose response—a test referred to as an oral glucose tolerance test (OGTT).
So, out of the options you provided, checking the urine for glucose (option b) would be one way to test for hyperglycemia. However, there are other tests that can be done as well.

What Is Internal Fertilization? Syngamy of gametes occurs inside the female body after insemination through copulationObserved in birds, mammals, birds occurring in terrestrial plants and animals, also in some of the aquatic entities. This is observed in three ways – ovoviviparity (eggs retained in the female body, hatched when fully developed, oviparity(egg-laying), viviparity(offsprings develop within the female body) Observes in plants such as bryophytes, pteridophytesWhat Is External Fertilization?Syngamy of gametes outside the female body/outer environment, notably in water bodiesObserved in few vertebrates, sea urchins, fish, aquatic invertebrates, almost all amphibiansDeposition of sperms and eggs by males and females in open surroundings is known as spawningBroadcast fertilization – used when sperms swim through the water uniting with eggs to fertilizeii) In humans, the process of fertilization takes place in the fallopian tube. During this process, semen comprising thousands of sperms are inseminated into the female vagina during coitus. The sperms move towards the uterus and reach the opening of the fallopian tube.✯ Hope this helps ✯

Which of the following statements about the Hardy-Weinberg principle are true?
Select all that apply.
It assumes certain forces are acting on a population.
It is used to model genetic equilibrium.
It assumes certain forces are not acting on a population.
It is used to model gene flow.
Answer:
-It assumes certain forces are not acting on a population
-It is used to model genetic equilibrium
It assumes certain forces are not acting on a population and It is used to model genetic equilibrium.
Thus, Mendelian genetics are discussed in the context of populations of diploid, sexually reproducing individuals in the Hardy-Weinberg Theorem.
This theorem argues that allele frequencies in a population won't change from generation to generation under a particular set of assumptions.
The anticipated genotype frequencies are p2, 2pq, and q2 if a population has two alleles at a particular site and the allele frequencies are p and q. Once a population is in Hardy-Weinberg equilibrium, its frequency distribution won't vary from generation to generation.
Thus, It assumes certain forces are not acting on a population and It is used to model genetic equilibrium.

why do blue whales explode when they die
Answer:
Gas build up inside the body.
Explanation:
When a blue whale dies, the body starts decomposing, and the gases cannot escape, resulting into the explosion.
Answer:
A decomposing whale carcass generates gases which build up inside their stomach and large internal organs. This then causes them to expand, but whale skin and blubber are tough so the gases become trapped inside. Whales can apparently hold in gasses, or the “death burp,” for long periods after they die, sometimes resulting in massive and extremely messy explosions.

What type of energy transformation takes place during cellular respiration? Use complete sentences to explain how energy is conserved during cellular respiration.
Answer: Chemical Energy
Explanation: Cellular respiration is the process of transforming chemical energy into forms usable by the cell or organism
Answer:
In this exercise, we will have to explain the transformation of energy in cellular respiration, as:
The type of energy transformation takes is chemical energy and the energy is conserved because The ATP molecule stores energy from cellular respiration and photosynthesis for immediate consumption.
Recalling how cellular respiration works we have:
Cellular respiration is a process by which organisms obtain energy to perform the most diverse activities. Cellular respiration occurs in mitochondria, in the presence of oxygen, and is divided into three steps: glycolysis, the citric acid cycle (or Krebs cycle), and oxidative phosphorylation.
How is energy stored in ATP?
Energy is stored in the bonds between phosphates. The molecule acts as a cellular currency, that is, it is a convenient form of energy transformation. The ATP molecule stores energy from cellular respiration and photosynthesis for immediate consumption.
