10. The cell membrane is?
A permeable. B. semi-permeable
C. impenetrable
Answer:
B, semi-permeable
Explanation:
Answer:
Semi-Permeable
Explanation:
This is due to the reason that cell membranes require water and other nutrients to enter the cell and waste to exit the cell in order for it to function properly. If the cell membrane were permeable, anything would be able to enter including harmful microbes. If the cell membrane were impenetrable, the cell would die as it would not be able to receive the nutrients and materials needs.

What is one of the reasons why Gregor Mendel chose to study pea plants?
Answer:
To study genetics, Mendel chose to work with pea plants because they have easily identifiable traits.
Explanation:
For example, pea plants are either tall or short, which is an easy trait to observe, with that being said pea plants grow quickly, so he could complete many experiments in a short period of time.
To study genetics, Mendel chose to work with pea plants because they have easily identifiable traits.
What are Pea plants?Pea plants are either tall or short, which is an easy trait to observe, with that being said pea plants grow quickly, so he could complete many experiments in a short period of time.One of the reasons why Gregor Mendel chose to study pea plants is because they reproduce sexually.
In Gregor Mendel's work on pea plants, he discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Parental genes are randomly separated to the reproductive cells so that s-ex cells contain only one gene of the pair.
Therefore, To study genetics, Mendel chose to work with pea plants because they have easily identifiable traits.

The correct answer is option (3) hydrogen bonding.
What is hydrogen bonding?
Hydrogen bonding refers to the formation of Hydrogen bonds, which are a special class of attractive intermolecular forces that arise due to the dipole-dipole interaction between a hydrogen atom that is bonded to a highly electronegative atom and another highly electronegative atom which lies in the vicinity of the hydrogen atom.

if a rock has a volume of 2cm3 and a mass of 12g what is its density
Answer:
If a rock has a volume of 2 cm³ and a mass of 12 gr, its density will be 6 gr/cm³.
Explanation:
Density is a parameter used in chemistry and physics, which relates the mass and volume of a solid or compound, establishing the amount of volume that occupies a given mass.
If we observe the density formula, we can see that the greater the mass, the greater the density, while the volume is inversely proportional, so the lower the volume, the greater the density. This formula is:
ρ = m/V
Therefore, according to the mass and volume of the rock
ρ = 12 grs / 2 cm³
ρ = 6 grs/cm³
Being the density of the rock equal to 6 gr/cm³.

Relate cell size to cell functions, and explain why cell size is limited.
Answer:
Cells are small to have a larger surface area to volume ratio
Explanation:
Since there is always things moving across the phospholipid bilayer of the cell, there needs to be a large surface area compared to volume. A good analogy that I use is elephants ears. They are huge but super thin to keep a large surface area to volume ratio. This lets heat diffuse from the elephant. Its the same thing with cell, maximizing the efficiency of the phospholipid bilayer.

Your friend Suzanne says that the Ancient Romans must have sent letters only when they were in love or wanted to wish their friends a happy birthday because that's what her family does. How would you describe Suzanne's behavior? Egotistic ethnocentric ethno-oriented scientifically tested
Answer:
ethnocentric
Explanation:
Based on this scenario, I would describe Suzanne's behavior as being ethnocentric. This is simply due to the fact that she is applying her own cultural customs to that of Ancient Romans which she has never met or dealt with their customs. She is simply using her own experiences from her culture and what she knows to explain other culture's behaviors, which is exactly what an ethnocentric person tends to do.
Mice have two unlinked allele pairs that affect fur color. The table shows how allele pairs affect fur color. The term “agouti” describes fur with pigmentation that changes in each hair from the shaft to the tip, giving the fur a banded appearance. Mice with the aa allele pair are albino, regardless of the second allele-pair combination.
What is the probability of albinism in the offspring of a cross between two mice with AaBb alleles?
3/16
1/16
9/16
4/16
Answer: 4/16
Explanation:
The probability of albinism in the offspring of a cross between two mice with AaBb alleles is 4/16.
What is Probability?This is an expression which tells how likely an event will occur. It is usually gotten by dividing the favorable number of outcomes by the total number of possible outcome.
The total number of possible outcome is 16 and the favorable number of outcomes (AaBb) is 4.
This means the probability is 4/16.

Suppose that a minnow eats 100 marsh plants in a year. How much DDT build up in the body of the minnow?
Answer:
10,000
Explanation:
because:
1 marsh plant= 1 DDT
a minnow = 100 DDT
if 1 minnow = 100 DDT
100 marsh plants = 100 DDT
you multiply 100 by 100
You get 10,000 as the answer.
Bioaccumulation is the accumulation of persistent substances, many times toxic substances, in the organisms' tissues. In the exposed example, if the minnow eats 100 plants, it will get 100 units of DDT.
----------------------
This problem states that
a farmer sprays DDT in a field.DDT reaches the marsh plants by the wind actionEach plant receives 1 unit of DDT, which remains in the plant by bioacumulation.When talking about bioaccumulation we refer to a net accumulation of metals and other persistent substances in the tissues of an organism.
Accumulation occurs during the individual's life and can be transmitted to other organisms in the trophic chain.
There are two ways in which an organism can get these substances,
from other living beings (trophic chain) by direct consumption from the soil, air, and water.
So, according to the introduction, each plant has one unit of DDT.
1 marsh plant -------------- 1 unit of DDT
We need to find out how much DDT gets one single minnow that eats 100 marsh plants in one year.
So here, we can just perform a three simple rule.
If one plant has 1 DDT units, how many units DDT are in 100 plants??If one minnow eats 100 plants in a year, how many DDT units does it get?1 marsh plant -------------- 1 unit of DDT
100 marsh plants ---------X = 100 units of DDT
If the minnow eats one plant, it will get one unit. But if the minnow eats 100 plants, it will get 100 units of DDT.

Please i need help fast! What societal, ecological, or technical constraints should resource managers consider before proposing solutions?
Answer:
Explanation:When the cumulative impact of humans was small, the environmental implications of ... Ecological constraints add one more set of considerations to the list. ... difficulty of finding short-term solutions that do not aggravate long-term problems. ... Rates of extraction of renewable resources should not exceed regeneration rates.
Answer and Explanation:
Social constraints refer to the social traits and behaviours that affect the project's sustainability within a public. Social constraints include informal norms comprising cultural preference or formal practices, for example, government rules, that a resource manager should consider before proposing a solution. Technical constraints are fixed technical design decisions that might not be altered. Most frequently, technical constraints are brought by the stakeholders at the onset of the plan. There are technical constraints that a resource manager should consider before proposing a solution such as programming language required for numerous reasons, platforms supported or operating system and frame work. Businesses are the most affected by ecological constraints. Ecological constraints such as social expectations and requirements, competitors' act, legal requirements, modification in business, and modification in technology that a resource manager should consider before proposing a solution. Ecological constraints are essential to the business that should be plan ahead.
