Answer:
[tex]Probability = 100\%[/tex]
Explanation:
Given
Crossing of a black chicken and a white chicken
Required
The probability of having erminette chicks
The genotype of a black chicken is represented as: BB
The genotype of a white chicken is represented as: WW
The genotype of an erminette chicken is represented as: BW
Using a Punnett square, we have:
[tex]\begin{array}{ccc}{} & {B} & {B} & {W} & {BW} & {BW} & {W} & {BW} & {BW}\ \end{array}[/tex]
The result of crossing the two chicken gives 4 BW out of a total of 4
i.e 4 erminette chickens out of 4 possible chickens
So, the probability is:
[tex]Probability = \frac{4}{4}[/tex]
[tex]Probability = 1[/tex]
Represent as percentage:
[tex]Probability = 100\%[/tex]

Answer:
The effeinty
Explanation:
If forests are strictly managed according to the maximum sustainable yield model, some biodiversity would still be lost because ________. species whose habitat depends on mature trees in the top canopy layer will be excluded forests are more susceptible to herbivore damage habitats for nesting birds are lost all the trees are of mature size leaving no room for new seedlings nearly all predators will be excluded
Answer: species whose habitat depends on mature trees in the top canopy layer will be excluded
Explanation:
The maximum sustainable yield refers to a biological resource maximum usable production which can be gotten at a particular period of time without the ability of the resource maintaining that particular production level reduced.
If forests are strictly managed according to this model, some biodiversity would still be lost due to the fact that species whose habitat depends on mature trees in the top canopy layer will be excluded.

Which organelle is responsible for transporting lipids in the cell? (1 point) O Golgi apparatus O rough ER O nucleus O mitochondrion
Answer:
Endoplasmic Reticulum (ER)
Explanation:
The organelle that is responsible for transporting lipids in the cell is Golgi apparatus. The correct option is A.
What is Golgi apparatus?A Golgi body, also renowned as a Golgi apparatus, is a cell organelle that aids in the processing along with packaging of proteins as well as lipid molecules, mainly proteins destined for cell export.
The Golgi body is a series of stacked membranes which is basically named after, Camillo Golgi the one who discovered it.
The Golgi apparatus transports, modifies, along with packaging proteins as well as lipids into vesicles for delivery to specific destinations.
The Golgi apparatus is a crucial organelle for cargo post-translational modification.
Golgi-resident enzymes including glycosyltransferases, glycosidases, and kinases mediate post-translational modification of secreted and membrane proteins.
Thus, the correct option is A.

In a sample of double stranded dna if 27% of the nitrogenous bases are thymine what percentage of nitrogenous bases are cytosine?
Answer:
73%
Explanation:
Given: 27%
To find: Percentage of nitrogenous bases are cytosine
Solve: [tex]\frac{27}{100}[/tex] × [tex]\frac{100}{1}[/tex]
Firstly, divide 100% by thymine and cytosine
[tex]\frac{100}{2}[/tex] = 50
Now, If it is 50 / 50, but thymine has 27 then subtract 27 from 100
100 - 27 = 73
So, the percentage of nitrogenous bases are cytosine 73%

Water reacts with minerals in some rocks and very slowly dissolves the rock. What type of weathering does this demonstrate?
Answer:
Salt wedging
Explanation:
Salt wedging is a natural phenomenon which occurs in rocks and stones. It is a physical weathering process. It is a process by which water enters into the small cracks on the rocks and form salt like NaCl and thereby enlarging the cracks.
Most water contains dissolved salts and when water enters into the small cracks of the rocks, the salt begins to grow and it exerts pressures on the walls of the crack thereby enlarging the cracks.
This type of phenomenon is mostly seen near the seacoast and in the arid regions.
Thus water reacts with the minerals in the rock and slowly dissolves the rock in salt wedging weathering process.

What process contains the enzymes that break the chemical bonds in your food in order to create usable energy?
Answer:
Cellular respiration
Explanation:
This is because cellular respiration is an aerobic process where the chemical bonds in food are broken down to release energy. This process produce energy which are useful for the body cells. Cellular respiration help to break down glucose. Glucose and oxygen are converted to carbondioxide and water and energy is released which form ATP.

Which of these mammals are native to Virginia
Armadillo
Camel
Kangaroo
Squirrel
(Don’t leave links)
Answer:
Right a way, we know that a camel or a kangaroo are NOT native to Virginia. Now we have the armadillo and the squirrel.
"Originally native to South America, the armadillo now ranges as far north as Texas, Oklahoma, Kansas, Louisiana and Florida." - so we can rule out armadillos!
Virginia has 4 different kinds of squirrels that are native, so squirrel would be your answer.

7. Fill in the blanks using the words: glucose | monosaccharide | energy | carbon | lipids | C6H12O6 | polysaccharide | carbohydrates All matter, must contain ________________________ to be considered organic. ______________________________, composed of starches and sugars are generally used in cells as a source of ___________________________. If a carbohydrate has more than one sugar, it is considered a _________________________________. The single subunit of a polysaccharide is a __________________________________. An example of a monosaccharide is __________________________ and its formula is ___________________________.
Answer:
Carbon, carbohydrates, energy, Polysaccharide, glucose, C6H12O6.
Explanation:
All organic matter must contain carbon in its composition then it can be considered as organic compound. Carbohydrate is composed of starches and sugars are generally used in cells as a source of energy. If a carbohydrate has more than one sugar, it is considered as a Polysaccharide. The single subunit of a polysaccharide is a glucose. An example of a monosaccharide is glucose and its formula is C6H12O6 . If a carbohydrate has one sugar, it is considered as a Monosaccharide whereas If a carbohydrate has two sugar, it is considered as a Disaccharide
The correct words for the given blanks are:
1. All matter, must contain carbon to be considered organic. Organic compounds are those compounds that have carbon and hydrogen bonds.
2. Carbohydrate is composed of starches and sugars are generally used as a source of energy. Starch is a stored form of energy in plants, whereas humans have glycogen as the stored form of energy.
3. If a carbohydrate has more than one sugar, it is considered a polysaccharide. Polysaccharides are starch, glycogen, and maltose.
4. The single subunit of the polysaccharide is a monosaccharide. It is the basic form of polysaccharides, which are combined by glycosidic bonds to form oligo or polysaccharides.
5. An example of a monosaccharide is glucose. Glucose is the primary substance required for the production of energy. Its formula is [tex]\rm C_6H_{12}O_6[/tex].
