is golgi apparatus a plant or animal cell?
Answer:
it's actually found in both plant and animal cells.
Explanation:
A major function of the golgi apparatus is the modifying, sorting and packaging of proteins for secretion. It is also involved in the transport of lipids around the cell, and the creation of lysosomes.
hope it helps hun :)
The Golgi apparatus is found in both plant and animal cell as it is one of membrane-bound organelle in all eukaryotes.
A Golgi body or Golgi apparatus is one of cell organelle that process and package proteins and lipid molecules, especially proteins exported from the cell to various destinations such as lysosomes, or secretion. In addition, the plasma membrane and
glycolipids and sphingomyelin are synthesized within the Golgi.found in eukaryotes onlyis a factory and transport vehicle for different molecules.found in all plant and animal cellspresent near the endoplasmic reticulum.Thus, the correct answer is - present in both plant and animal cell as it is one of membrane-bound organelle in all eukaryotes.

If 100 mice are bred, how many red eyed white mice would you expect?
Answer:
6
Explanation:
In this scenario, black fur (F) is dominant to white fur (f) and black eyes (E) are dominant to red eyes (e). So in this case you would be looking for all lowercase letters in the punnet square, which would only be 1 mouse with white fur and red eyes (ff ee), and since there are 16 potential genotypes for offspring and only 1 that would be white with red eyes, you would divide 1 by 16 and get 0.0625, then you would multiply 0.0625 by 100 (total number of mice) and you would get 6.25. since you can't really have .25 of a mouse (that would be kind of gross) you round down and get 6, the closest answer.
(Also I just took this quiz and got this question right. Just wanted to confirm that in case you had any doubts!)

Both.
Explanation:
Both animal and plant cells have mitochondria, but only plant cells have chloroplasts. Plants don't get their sugar from eating food, so they need to make sugar from sunlight.
Answer:
Both.
Explanation:
Without mitochondria, cells would not be able to function, no matter what type they are. Mitochondria is the powerhouse of the cell! Hope this helped
what is the biodiversity score of farmland (maize)?
Answer:
Required Answer:-The intensification of agriculture has caused dramatic declines in farmland biodiversity (Carvalheiro et al., 2013; Senapathi et al., 2015). Since the 1990s, agricultural policies have been developed in Europe to mitigate this loss through agri-environmental schemes (AES). One AES is “sown wildflower strips”, the aim of which is to create new ecological infrastructures by sowing attractive wild flowers on arable land (a few % of the cultivated area). These ecological infrastructures fall within our definition of MIMS since they represent a massive introduction of managed species in the landscape.

An on-going research study has been tracking the dietary preferences of gorillas in the wild. Researchers are hoping to formulate a diet for gorillas in captivity that mimics those living in their natural habits. By reproducing the preferred diet, researchers hypothesize that the eventual release back into the natural habitat will be an easier transition for the gorillas.
Researchers are using various methods to make observations and collect data about the feeding habits of gorillas in the wild. Which method would be classified as direct observation?
A) Counting and classifying the debris in the area where the gorillas live.
B) Observing the gorillas from a protected location and recording what they eat.
C) Surveying the natives in the area about the diet of the local gorilla population.
D) Photographing the habitat of the gorillas in a before and after scenario and seeing what is missing from the after photograph.

1- Evaporation:-
Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. For more evaporation, the area that surrounds the surface of the water must be less humid i.e. it should not already be concentrated have the water vapors. For the evaporation we need to increase the temperature of the molecules of water on the surface, which is caused by the Sunlight.

The type of stem cell that gives rise to red and white blood cells is called a hematopoietic stem cell and is present in Option C, as hematopoietic stem cells are multipotent stem cells that reside in the bone marrow.
What is a hematopoietic stem cell (HSCs) ?
Hematopoietic stem cells are a type of stem cell that give rise to all types of blood cells, including red blood cells, white blood cells, and platelets, and they reside in the bone marrow and are responsible for replenishing the body's blood cells. They have the ability to differentiate into a variety of cell types, and the process by which HSCs differentiate into the different types of blood cells is tightly regulated by various factors, including growth factors.
Hence, the type of stem cell that gives rise to red and white blood cells is called a hematopoietic stem cell and is present in Option C.

You have been provided with a non-polar liquid and are trying to determine whether
it is hydrophilic or hydrophobic. You place one milliliter of the substance into a
beaker filled halfway with water. Describe what will happen next.
Answer:
Explanation:
Non-polar liquids are liquids that have covalent bonds in which the shared electrons are shared equally. The molecules of these liquids are repelled by the molecules of water and hence do not dissolve in water. Thus, non-polar liquid are hydrophobic (water dislike/insoluble in water).
When one milliliter of the substance is placed into a beaker filled halfway with water, the substance will be seen "compact" (not dissolving nor interacting) in the beaker of water.
Polarity is defined as the separation of electric charge in a molecule or having an electric dipole moment due to the difference between negative and positively charged ends.
In the given experiment when one milliliter of the substance into a beaker is filled halfway with water, the substance will be seen as coagulating or not dissolving in the water.
The non-polar are the compounds or liquids that do not dissolve in the water. The non-polar molecules are the molecules, which are attracted to the alike molecules, rather than the water molecules.
The non-polar compounds have covalent bonds, in which the electrons are shared among the atoms of the compound.
The molecules of these liquids are repelled in the presence of water or are hydrophobic. These liquids do not dissolve in water.
Therefore, the liquid is hydrophobic.

Why is a red laser pointer an example of a poor blackbody radiator?
A. It glows less brightly as electromagnetic radiation is released.
O B. It gives off a range of wavelengths of electromagnetic radiation.
C. It gives off only one wavelength of electromagnetic radiation,
D. It keeps the same temperature and gives off no electromagnetic
radiation
A red laser pointer is a poor blackbody radiator because it emits electromagnetic radiation at only one wavelength. So, the correct option is C.
What is blackbody radiator?Depending on its temperature, a blackbody radiator is an object that radiates at different wavelengths. Blackbody radiation is the radiation that a blackbody radiator emits, and it exhibits a certain pattern known as Planck's law.
A red laser pointer, on the other hand, produces a narrow, focused beam of light at a specific wavelength, typically around 650 nanometers. This indicates that, unlike a blackbody radiator, a laser pointer does not generate radiation at different wavelengths. A red laser pointer is therefore a subpar blackbody radiator.
Therefore, the correct option is C.
