When the exponential phase of a logistic growth curve of the population ceases

What is the correct order of levels of organization in an organism, from the least complex to the most complex?

In-s [12.5K]

The answer is letter D.

The levels of organization of life from the least complex to most complex are enumerated below:
a. Organelles - the basic part of a living organism. It refers to the different structures of the cell, whether prokaryotic or eukaryotic. (Ex. Mitochondria, nucleus)
b. Cells - building blocks of life that are composed of different molecules responsible for the function of an organism. (Example: prokaryotic, eukaryotic cells)
c. Tissues - combinations of cells that carry out a specific function in an organism. (Example: Human skin)
d. Organs - collections of tissues that perform specific functions. (Ex. heart, lungs)
e. Organ Systems - composed of interconnected organs that function as a whole. Many organisms, particularly mamamals, are composed of organ systems. (Ex. respiratory, circulatory systems)
f. Organisms – individual entities that specifically make-up a population. (Ex. Each tree in the forest is an organism, each animal in sea is an organism)
g. Population – species living within a specific location. It could be the same or different species that inhabit a place. (Ex. Birds are species in the forest as well as bears)
h. Community – refers to the total number of populations that inhabit a specific location. (Ex. All of the trees, insects, birds that inhabit the forest are a community)
i. Ecosystem – consists of all living things that function together as a group which also includes the non-living parts of the environment. (Ex. Rain water, nitrogen in the soil)
j. Biosphere – the highest organization of life that consist of all the collection of ecosystems in the planet. It includes the land, air, water, even the atmosphere of the planet.

1. A couple of mice with brown fur and black eyes had litter with the following distribution of traits: 9 with brown fur and bla

Ierofanga [76]

Answer:

The genotype of the couple of mice is heterozygous.

Explanation:

First, we going to classify each trait as dominant or recessive allele:

Brown fur: It’s a dominant allele because 12 of 16 mice have brown fur, therefore 75% of the litter have this trait.

Black eyes: It’s a dominant allele because 12 of 16 mice have black eyes, therefore 75% of the litter have this attribute.

Grey fur: It’s a recessive allele because only 4 of 16 mice have this trait, so 25% of the litter have grey fur.

Red eyes: It’s a recessive allele because 4 of 16 mice have red eyes, so 25% of the litter show this trait.

Second, we going to name each phenotype with a letter and use a capital letter for dominant allele or a small letter for recessive allele.

For the color of the fur, let’s use letter “F”:

F: Brown fur

f: Grey fur

For the color of the eyes, let’s use letter “E”:

E: Black eyes

e: Red eyes

The genotype of each phenotype is conformed by two letters that indicates, the recessive allele is showed in the phenotype only when both letters in the genotype are small letter.

For example, for fur, there are three combinations:

FF: Brown fur (two dominant alleles)

Ff: Brown fur (A dominant allele and a recessive allele)

ff: Grey fur (Two recessive alleles)

For eyes, there are also three combinations:

EE: Black eyes (two dominant alleles) (

Ee: Black eyes (A dominant allele and a recessive allele)

ee: Red eyes (Two recessive alleles)

When both allele of the genotype are dominant or recessive, it is heterozygous, if there are a dominant allele and a recessive one, it is a homozygous.

Since there are 7 mice that show recessive phenotype, that means the genotype of the couple of mice are heterozygous. Although, both mice show a dominant phenotype, the genotype have a dominant allele and a recessive allele.

The genotype for the couple of mice is:

FfEe x FfEe

So, when we apply the Mendel's third law, we got the results showed in the chart.

Cells are placed in a solution that causes them to absorb liquid until they burst. When more water is removed from the solution,

LuckyWell [14K]

Answer:

Cells are placed in a solution that causes them to absorb liquid until they burst. When more water is removed from the solution, newly added cells do not burst. The original solutions was hypertonic solution , while the second was hypotonic solution to the cells.

What are the three different ways living things consume energy and how are they labeled?

34kurt

Energy is the ability to do work. The form of energy that living things need for these processes is chemical energy, and it comes from food. Autotrophs make their own food. Heterotrophs obtain food by eating other organisms. Organisms mainly use the molecules glucose and ATP for energy.
