Bee orchids are flowering plants that look like they have a female bee resting on them. Bee
orchids produce a scent that mimics hormones released by female bees. This scent attracts
male bees that are seeking a mate. When a male bee lands on the orchid, pollen becomes
stuck to the hairs on the body of the bee. The male bee then transfers the pollen to other bee
orchids.

How has this adaptation given the bee orchids a reproductive advantage?
Answers
Answer:
The adaptation makes the orchids more desirable to bees, and therefore more likely to be able to reproduce than other plants without the adaptation.

How do u merge two. Atoms together and. Make a nucleus atirficially
Answers
Some atoms, though, want to have more or less electrons around them than they do. So they form things called bonds that let them share electrons with each other. (There are lots of different kinds of bonds, but this is the basic idea.) When they're sharing electrons, they're totally stuck together and become what's called a molecule.
(added by Mike W.: Those types of bonds are called ionic bonds, where one atom grabs an electron from another and the resulting charged ions stick together by electrical attraction. Bonds can also form even between atoms which are just like each other, so that neither ends up with more or less electrons than it started with. Common examples are the oxygen and nitrogen molecules in the air. Here the reason that the atoms stick together is that the electron clouds, described a bit in that link above, can lower their energy by spreading out over two atoms instead of one, for reasons that one can't begin to describe without quantum mechanics. These covalent bonds are very common and often the strongest bonds around.)
Some atoms, though, don't want to have any more or less electrons than they have. So they don't form bonds with any other atoms. (An example of this is Helium.) So they don't bond at all. (Mike W.: What this really means is that every electron is stuck well, in a low energy state. The next state available would have much higher energy. Only very weak bonds can form with other atoms. The reasons why there are particular states around with different energies are also entirely due to quantum mechanics.))

Why does the mitochondrial gene tree suggest a later split? Why the disparity between the nuclear gene tree?
this is the link: https://learn.genetics.utah.edu/content/evolution/bears/
Answers
Answer:
Why does the mitochondrial gene tree suggest a later split?The mitochondrial gene tree suggests a later split because it occurred hybridization later in time, with the transference of the brown bear mitochondrial genetic information to the polar bear population. So the mitochondrial gene tree exhibits a later divergence.
Why the disparity between the nuclear gene tree?Because the first divergence event of the common ancestor occurred 60,000 years ago, evidenced by nuclear DNI and mitochondrial DNI. However, 100,000 years ago, concerning the mitochondrial genetic material, the hybridization event defined a new more recent common ancestor between the two species.
Explanation:
The use of mitochondrial DNA might present a few problems that need to be considered in evolution studies. It involves only one locus, so it has some limitations when reconstructing history, especially if the locus went through any process, such as natural selection, bottleneck events, or its transference to another population due to hybridization. There is also a high possibility of an incomplete reconstruction of the population history if males and females have different dispersal patterns.
The most proper way of reconstructing history is by complementing mitochondrial information with nuclear genetic information and evaluating their concordancies.
In the exposed example, 600,000 years ago, the original species split into the polar bear and the brown bear. But 100,000 years ago, hybridization occurred between a brown bear female and a polar bear male. The offspring joined the polar bear population, carrying the female genetic information, nuclear and mitochondrial. With time, these individuals interbred with the polar bears, diluting the nuclear brown bear genetic information. However, females carrying the brown bear mitochondrial DNI seemed to be more successful reproductively than the polar bear females. The mitochondrial information, hence, has been in the population for many generations, until today. And this information came from a more recent common ancestor, compared with nuclear genetic information.

Explanation:
Sperms and hormone testosterone are produced by Testes.
What is Testes?
A testicle, which is pronounced "teh-stuh-kl," is a component of the anatomy of men and those who are born male . You typically have two testicles. These organs produce hormones and sperm.
Male gonads or testes (pronounced "teh-steez") are other names for your testicles. A testis is a single testicle.
The temperature of your testicles is roughly two degrees Celsius lower than the rest of your body. Spermatogenesis, the production of sperm, benefits from cooler temperatures.
Therefore, Sperms and hormone testosterone are produced by Testes.

The area of north pole has not the part of any country or the north pole does not lie in any country. The main reason of the coldness of the north pole and south pole has that they do not receive any direct sunlight. The best time to visit the north pole has the time of June and July because in this month the ice of the north pole is thinner as compared to other months.

A marble dropped from the Foshay Tower in Minneapolis hits the ground at 52 m/s. How high is the Foshay tower?
Answers
Answer:
Height of the Foshay tower is 138 m
Explanation:
Using the third equation of uniformly-accelerated motion under gravity:
v² = u² + 2gh
Where v is final velocity,
u is initial velocity,
g is acceleration due to gravity,
and h is height
v = 52 m/s;
u = 0 (since the marble was dropped from rest at a height above the ground);
g = 9.8 m/s²,
h = ?
(52 m/s)² = 0 + 2 × 9.8 m/s² × h
2704 m²/s² = 19.6 m/s² × h
h = 2704 m²/s² / 19.6 m/s²
h = 138 m
Therefore, height of the Foshay tower is 138 m

What is Prereading?
Before attentively reading a text (or a chapter of a text) from beginning to end, pre-reading is the process of scanning the material to identify essential concepts. sometimes known as surveying or previewing.
Pre-reading gives you an overview, which can help you read more quickly and effectively. Examining (and considering) chapter titles, summaries, headings, subheadings, study questions, and conclusions are typical pre-reading activities.
Students can use pre-reading tactics to anticipate what they will read or hear by considering what they already know about a particular topic. Teachers can focus on a book's organization, teach new vocabulary or other concepts, look for the primary idea, and provide students a reason for reading or listening before they even begin to read any material.
