Answer:
B
Explanation:
In intensive grazing, rangeland is divided into paddocks. A paddock is
a small field or enclosure. Animals can graze on each paddock for a
short time before being moved to a new area. This type of system
provides high-quality pasture for dairy cows and growing animals but
requires increased management to move the livestock.
What do prokaryotes lack that are in eukaryote cells?
Answer: Prokaryotic cells differ from eukaryotic cells in that they lack any membrane-bound organelles, including a nucleus. Instead, prokaryotic cells simply have an outer plasma membrane, DNA nucleoid structure, and ribosomes.

Cells often need to take in materials from their environment which are
found in lower concentration outside the cell compared to inside the cell.
In order to do this, cells must use energy from ATP to move these materials
against the concentration gradient through active transport.
with the concentration gradient through active transport.
against the concentration gradient through passive transport.
with the concentration gradient through passive transport.
Answer:
With the concentration gradient through passive Transport
Explanation:
I haven't taken biology recently, but if I'm not mistaken, cells that use ATP can only passively do things.
Cells often need to take in materials from their environment which are with the concentrate gradient through passive transport. So the correct option is D.
What is passive transport?A kind of cellular transport known as passive transport involves the movement of molecules and ions along concentration gradients. It indicates that a drug has a propensity to migrate from a region of higher concentration to a region of lower concentration.
When there are few substances anywhere, those substances tend to migrate there. Contrary to active transport, another kind of cellular transport, which fundamentally requires ATP to move substances against their concentration gradient, the method does not involve metabolic energy (e.g. ATP) since the chemicals are moved downwards or along their concentration gradient. The four main methods of passive transport are osmosis, filtration, simple diffusion, and assisted diffusion.
When a drug is transported passively, it is moved from an area of higher concentration to one of lower concentration. As a result, chemicals migrate along a gradient of concentration.
Therefore the correct option is D.

Muscles like the diaphragm and intercostals contract and expand the chest cavity to lower pressure for breathing. This is an example of how the respiratory system interacts with the
Answer:
Environment.
Explanation:
The respiratory system interacts with the environment by contracting and expanding the diaphragm and chest in order to do breathing. When the muscles in the diaphragm contracts and the expansion of chest occurs, takes the air inside the body that is present in the outside environment for inhalation of oxygen while on the other hand, when the diaphragm expands and chest contract, the air inside the body is removed with the removal of carbondioxide gas.

What type of species is most likely to lead to extinction of another species? a Invasive species b Native species c Genetically isolated species d A and B
Answer:
A
Explanation:
Like Christopher Columbus
:)
The type of species that is most likely to lead to the extinction of another species is known as Invasive species. Thus, the correct option for this question is A.
What is Species?Species may be defined as a cluster of organisms that can reproduce with one another in nature and produce fertile offspring.
Invasive species are those that are not native to a particular habitat. They just arrive there in search of resources that support them in order to survive and reproduce naturally.
These arrived species utilize the resources like food, space, etc. of the native species and make them oppressed to eliminate from this habitat.
Therefore, invasive species is the type of species that is most likely to lead to the extinction of another species. Thus, the correct option for this question is A.

using Punnett Squares, determine the percentage of offspring which would be heterozygous from the following cross: BB x bb
A. 25%
B. 50%
C. 100%
Lets take that the father has black hair and the mother has brown hair so -->
Male × Female
Genotypes: BB × bb
Phenotypes: Black brown
Gametes: B _100%_ b_100%_
After reviewing the photo
we have
Genotypes
B: 50% (1/2)
b: 50% (1/2)
Phenotypes
Black: 50% (1/2)
brown: 50% (1/2)
Using Punnett Squares, the percentage of offspring would be heterozygous from the following cross: BB x bb is 25%. Therefore, option (A) is correct.
What are the features of punnett square method?The Punnett square is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment. It is named after Reginald C. Punnett, who devised the approach in 1905.
The Punnett square is a table in which all of the possible outcomes for a genetic cross between two individuals with known genotypes are given. In its simplest form, the Punnett square consists of a square divided into four quadrants.
A Punnett Square is a helpful tool that helps to predict the variations and probabilities that can come from cross breeding. This includes predicting crossing plants, animals, even humans with each other.

How can charging occur?
The previous section of Lesson 2 discussed the process of charging an object by friction or rubbing. Friction charging is a very common method of charging an object. However, it is not the only process by which objects become charged. In this section of Lesson 2, the charging by induction method will be discussed. Induction charging is a method used to charge an object without actually touching the object to any other charged object.

All are characteristic of allosteric enzymes except:
a. effectors may show stimulatory or inhibitory activity
b. they have multiple subunits
c. they obey Michaels-Menten kinetics
d. the regulatory effect is by altering conformation and interation of subunits
e. binding one subunit impacts binding of substrate to other units.
Answer : They Obey Michaels-Menten kinetics ( c )
Explanation:
Allosteric enzymes are enzymes that posses the presence of an additional site and an active site. they are modified by a noncovalent binding an allosteric effector. They do not posses a kmvalue hence they do not obey Michaels-Menten kinetics

Explain why a leaf kept in the light for 24 hours will turn an iodine solution blue-black, whereas a leaf kept in light for 24 hours and then in the dark for 24 hours will have no effect on an iodine solution
Answer:
The leaf kept in the light will turn blue-black because of the presence of starch after photosynthesizing. The leaf in the dark could not photosynthesize, which would not create starch so the iodine solution will have no effect.
Explanation:
Iodine stains a blue black in the presence of starch

What is photosynthesis
Answer:
The process of a plant converting sunlight, carbon dioxide and water into food
Explanation:
Hey there!
Photosynthesis is the reaction that converts light energy to chemical energy in sugar and carbohydrates. Humans can't eat sunlight, so we eat plants. Plants convert the energy in the sunlight into chemical energy using chlorophyll. Chlorophyll is a molecule produced by plants, algae, and cyanobacteria, which aids in the conversion of light energy into chemical bonds. It is the green pigment found in the chloroplasts of higher plants. They are a part of our ecosystem, and they are lower on the food chain.

Calculate the heat energy of 100 g of water that has its temperature increased by 10C . The specific heat of water is 4.18 J/gC
Answer:
4180 Joules
Explanation:
Multiply 100g by the 10c to get the amount of degrees heating the amount of grams, which is 1000.
Specific heat is how much energy it takes to heat 1 gram 1 degree celcius, which it took 1000 of.
1000* specific heat for water = Total heat energy
1000*4.18J=4180 J
It took 4180 Joules of energy to heat up 100g of water by 10 C
