Answer:
There are many unique physical features that pigeons have.
Explanation:
Pigeons, according to studies, are surprisingly complex creatures. They have passed the "mirror test"(self recognition), can recognize others, and can recognize every letter of the human alphabet.
There are also incredible physical features.
Plumage is one of these. Their plumage varies, and is unique to the type of pigeon they are. Not only this, but they have the ability to walk, while most other birds hop about.
Something absolutely extraordinary about them is that they have a gland in their throat. That gland actually secretes milk for their offspring, so they have adequate nutrition to grow and develop.
Hope this helps.

Under which circumstance does Mendel’s principle of independent assortment hold? a. only when there is crossing over b. only when traits are tightly linked (close together) on the same chromosome c. only when traits are on different chromosomes d. only when the traits are not influenced by selection
Answer:
c
Explanation:
Mendel's principle of independent assortment holds only when traits are on different chromosomes.
The independent assortment principle states that genes assort independently of one another. In order words, traits are independently inherited by offspring from parents. For example, the trait for eye color is independently inherited from skin color, height is independently inherited from feet size, and etc.
This principle only holds true when genes are located far away from one another on the same chromosome or when they are on different chromosomes entirely. Once genes are close to one another on the same chromosome, they become linked together and no longer independently inherited.
The correct option is c.

When someone challenges your opinion, you should ___________________. A. repeat your opinion again until they are convinced. B. acknowledge their opinion and make sure you have a valid argument to respond with. If you do not have a valid argument, you may be in the wrong. C. ignore them, their opinion doesn’t matter when you have already formed your own opinion. D. accept their opinion as correct, especially if they have a degree.
Opinions are the views formed concerning something. When an opinion is challenged, then one should acknowledge them and ensure that a valid argument is presented in the counterclaim. Thus, option B is correct.
What is a counterclaim?A counterclaim is a rebuttal made against the claim made previously and is the response of an individual to the presented opinions or judgments. It is generally presented to clear and oppose the ideas claimed by the opposition.
If an idea of a person is challenged then the person can respond by presenting a reasonable argument that can validate the ideas and opinions as true and accurate rather than getting them as incorrect.
If a valid argument is not presented then there might be a possibility that the ideas and opinions presented were not true or correct.
Therefore, one should acknowledge other people's opinions by providing a valid argument.

A mineral crystallizes from magma deep inside Earth.
Which characteristics can be determined given only the information above?
O luster
streak
O crystal size
O crystal structure
Answer:
It's crystal size.
Explanation:
The magma in the earth isn't cooling yet, the slower the cooling, the larger the crystals,
Pls, mark brainliest
From the given information the crystal size can be determined. The crystal size can be studies from the crystallization and cooling rate of magma.
What are minerals?Minerals are inorganic solids that exist in nature and have a distinct chemical composition and crystalline structure. Even though thousands of minerals in the earth have been found, only ten minerals such as quartz, orthoclase, pyroxene, calcite, biotite, garnet, clay etc. make up the majority of the crust's volume.
Mineral rock have to property of lustering such as polished metals and they reflect the light in color. The color of the powder of the crystalline mineral is called streak.
As the magma cools, the size of crystal becomes large. It is proved that from the cooling rate of magma, the crystallization and crystal size can be determined.
Hence, crystal size can be determined from the given information and option C is correct.

How many neutrons are The process of fusion and fission are completely different. Fusion combines two light atoms together and fission splits the nucleus of a large unstable atom. What is the MAJOR similarity between the two? in the isotope Carbon-14?
Answer:
Examples of fission and fusion
For example, the so-called hydrogen bomb (or H bomb) is actually a deuterium–tritium bomb (a D–T bomb), which uses a nuclear fission reaction to create the very high temperatures needed to initiate fusion of solid lithium deuteride (6LiD), which releases neutrons that then react with 6Li, producing tritium.

Bart has to babysit Maggie for several nights in a row during summer vacation and makes a bet with that Taylor Swift music will get Maggie to Bart gets out the CD collection and when Maggie cries the first night, he plays The second time he plays /DC and rocks out, but she doesn't stop crying. The third time he plays Taylor Swift. When he plays Taylor Swift, Maggie immediately and starts to smile. •What is the independent variable? •What is the hypothesis? •What is the dependent variable? •Milhouse says Bart needs to try to see what Maggie will do if he doenst play any music At all. What is this called?
Answer:
Independent variable: THE TYPE OF MUSIC PLAYED
Dependent variable: MAGGIE'S TEARS
Hypothesis: IF Taylor Swift's music is played, THEN Maggie will stop crying
Control group
Explanation:
The hypothesis of an experiment is a testable explanation given to possibly solve an observed problem. In this question, Maggie thinks Taylor Swift's music will get Maggie to stop crying, hence, one can hypothesize that: IF Taylor Swift's music is played, THEN Maggie will stop crying
Independent variable is the variable that the experimenter manipulates or changes in order to bring about an outcome. The independent variable in this experiment is the THE TYPE OF MUSIC PLAYED by Bart because it is what is changed.
Dependent variable is the variable that is being measured. It responds to the changes made to the independent variable. In this experiment, the dependent variable is MAGGIE'S TEARS.
Milhouse says Bart needs to try to see what Maggie will do if he doenst play any music At all, this is called the CONTROL GROUP because the control group of an experiment is the group that does not receive any experimental treatment i.e. the independent variable is not added.

In the thylakoid membranes, what is the main role of the antenna pigment molecules?
a) split water and release oxygen to the reaction-center chlorophyll
b) harvest photons and transfer light energy to the reaction-center chlorophyll
c) synthesize ATP from ADP and Pi
d) concentrate photons within the stroma
Answer: Option B.
harvest photons and transfer light energy to the reaction-center chlorophyll
Explanation:
In the thylakoid membranes,the main role of the antenna pigment molecules is harvest photons and transfer light energy to the reaction-center chlorophyll because the photon of light move until it get to a molecule in the chlorophyll. When it reaches the molecule, it causes an excitation of electrons in the chlorophyll. The energy then present allow it to break free from the chlorophyll atom, which indicate chlorophyll donating an electron and the energy that is absorbed is then converted to heat.
