When two species are forced to interact in a particular environment, how would
relationships of competition, predation, and mutualism affect the two populations?
Answer:
Find the explanation below.
Explanation:
When two species find themselves in the same environment, the quest for survival would lead to interactions among themselves.
Competition would result when there are limited resources. For example, when Tigers and Lions who feed on the same prey exist together in an environment, a competitive relationship can result.
Predation is a sort of interaction where an organism feeds on a prey to survive. Here, the weaker animal/species stands the risk of being defeated in the battle for survival. For example, in some homes where cats and rats exist, the cats tend to prey on the rats.
Mutualism is a form of symbiotic relationship where the animals exist together in a cooperative manner. Most fungal species have been found to have a mutualistic relationship with the roots of plants. Each of these two is important to each other's survival.

In pigeons, the allele B produces blue feathers. The allele W produces white feathers. The B and W alleles are codominant. A blue and white pigeon BW is crossed with a solid white pigeon WW. What percent of the offspring are expected to be blue and white?
Answer:
The correct answer is - 50%.
Explanation:
Codominance is a type of inheritance that takes place when the genotype of an individual organism in heterozygous condition express traits of both alleles.
Cross between blue and white pigeon and pure white:
BW × WW and gametes will be B and W and W and W
B W
W BW WW
W BW WW
There are 50% of BW that is blue and white pigeons
A cotransporter is something that moves two substances across a membrane, one passively and the other actively. The Na+/ K+ ATPase transports sodium and potassium ions across the plasma membrane against their concentration gradients. This pump is not considered a cotransporter because
Answer:
both ions are transported actively
Explanation:
If both ions are being transported against their concentration gradients, then they are both being transported by active transport, as it requires energy.
A co-transporter moves two substances across the membrane, one passively and one actively. But in this case neither ion is moved passively, so it cannot be considered a cotransporter

The protein, lipid, and carbohydrate compositions of the cytoplasmic and extracellular sides of membranes are different from one another. Why is this the case? (3 points)
a) Some membrane components are synthesized outside of the cell, while others are synthesized in the cytosol.
b) The two sides of a cell membrane face different environments and carry out different functions.
c) The molecular composition of the inner and outer layers of the cell membrane is determined by genes.
d) Proteins only function on the cytoplasmic side of the cell membrane, which results in asymmetry across the membrane.
Answer:
The protein, lipid, and carbohydrate compositions of the cytoplasmic and extracellular sides of membranes are different from one another , this happens because the two sides of a cell membrane face different environments and carry out different functions.
Explanation:
PROTEINS , LIPID AND CARBOHYDRATES , all are the components of the plasma membrane , located at different sites .
PROTEINS -: The main component of plasma membranes is proteins. Two key categories of membrane proteins are available: integral and peripheral. As their name implies, integral membrane proteins are incorporated into the membrane: they have at least one hydrophobic region that anchors them to the phospholipid bilayer's hydrophobic center. Others just stick partway through the membrane, while others extend from one side of the membrane to the other and on either side are exposed.
On the outside and inside surfaces of membranes, peripheral membrane proteins are found which are bound either to integral proteins or to phospholipids. Peripheral membrane proteins do not stick into the hydrophobic center of the membrane as opposed to integral membrane proteins, and appear to be more loosely bound.
LIPID -: Phospholipids, arranged in a bilayer, make up the plasma membrane 's essential cloth. Since they are amphipathic, they are well-suited for this function, meaning they have both hydrophilic and hydrophobic regions.
The hydrophilic or "water-loving" component of a phospholipid is its head, which includes a phosphate group that is negatively charged, as well as an additional small group that can also be charged or polar.
Its long, nonpolar fatty acid tails make up the hydrophobic, or "water-fearing," portion of a phospholipid. The tails of fatty acids can interact easily with other non-polar molecules, but interact poorly with water.
CARBOHYDRATES -: The main component of plasma membranes is carbohydrates. In general, they are located on the outer surface of the cells and are either bound to proteins (glycoproteins forming) or to lipids (glycolipids forming). These chains of carbohydrates can consist of 2-60 units of monosaccharide and can either be straight or branched.
Hence , the correct option is B.
What's the difference between inference and observation? Give examples of each.
Answer:
A inference is a conclusion reached on the basis of evidence and reasoning.
A observation is an act or instance of regarding attentively or watching
Explanation:
Example for a inference would be - lets say you notice someone isnt acting like theirself you may infer that their not having a good day or their not in a mood
Observation example- when your doing a lab for science you may observe the different types of utensils or the effects of the object you use like oh this is blue or something

What is the relationship between population number and carrying capacity in a stable population
Answer:
As a population grows in an area, a population may experience the effects of increased densities. In a given area, is the maximum population size of the species that the environment can sustain is called the carrying capacity. Carrying capacity is determined by the amount of available resources (food, habitat, water).

Explanation:
Which would have most likely stopped Mendel from finding a pattern in his results?
O A. If seed shape did not have a clearly recessive form
B. If having a smooth seed had been a dominant trait
C. If having a wrinkled seed had been a recessive trait
D. If garden peas produced large numbers of offspring
Answer:
A. If seed shape did not have a clearly recessive form
Explanation:
To study inheritance patterns, Mendel studied a few characteristics of pea plant -e.g. pea colour, shape, plant height. These characteristics had to be very clear dominant and recessive forms to distinguish between, otherwise detecting the patterns would not have been obvious.
For example, if crossing a wrinkled seed plant with a smooth seed plant made a semi-wrinkled plant, Mendel would not have been able to study the inheritance of dominant and recessive traits.
Answer:
A. If seed shape did not have a clearly recessive form.
