I need to breed all white mice for the genetics class visiting from a High School in a few weeks. I only have white males and black females. (Black is the dominant fur color) What would the genotype of the parent mice need to be to get the most white mice for my money? What genotypes would the
parents need to give only heterozygous offspring? Show each of these crosses (only heterozygous offspring, and maximum white offspring) on the Punnett squares below.

Answer:

The correct answer is = 2.5× 10^7.

Explanation:

Colony Forming Units/ml (CFU/ml) in the original sample can be calculated by the countable plate is multiplied by 1/FDF.

Given:

colonies counted on the plate = 250

Forming dilution factor = 10^5

solution:

CFU/ml = 250  x 1/1/100000

= 250 CFU x 100000

= 250,00,000 CFU/ml

= 2.5× 10^7

The grey matter includes neural cells, dendrites, and axon terminals, whilst white count number consists of axons and myelin.

The white rely takes place in both the brain and spinal wire. but, gray be counted is a large part of the mind. the main difference among white rely and grey rely is that white count number mainly incorporates myelinated axons and gray matter specifically consists of cells, axon terminals, and dendrites.

Gray be counted is a grey area across the critical anxious machine of the CNS. A combination of neuron bodies of interneurons and motor neurons and neuroglia. Synapses from grey matter. White depend does not incorporate the bodies of neuron cells however millions of axons and neuroglia.

3. keeping your environment clean

Answer:

Sleep inertia, which is a normal part of the waking process. Your brain typically doesn't instantly wake up after sleeping. It transitions gradually to a wakeful state. During this transition period, you may feel groggy or disoriented.

Answer:

is due to sleep inertia... your body may be awake but brain is not active yet

Answer:

d isotope concentration

Explanation:

A fossil can be defined as the mineral impression or remains of living organisms such as plants and animals that are prehistoric in nature.

Isotopes can be defined as the atom of an element that has the same number of protons but different number of neutrons. This ultimately implies that, the isotopes of an element have the same atomic number (number of protons) but different atomic.

We can accurately determine the age of a rock or fossil by measuring its isotope concentration. This can be achieved through the use of radiometric dating.

In Science, this process is known as absolute dating and it can be defined as a process used to accurately determine the age of a rock or fossil by measuring the decay of isotopes associated with the rock or within the fossils.

Hence, these informations when properly obtained is used to determine the age of a rock or fossil because the parent material decays into a stable daughter elements at a constant decay rate.

No, the white color of Migaloo is not most likely an advantage in its current environment. This is because white is the color that is easily perceived by predators.

A mutation may be defined as sudden, stable, and inheritable changes in the genetic material of an organism. An organism that undergoes an event of mutation is known as a Mutant. The agents of mutation are known as mutagens.

White color is easily perceived by predators as compared to black, brown, grey, etc. So, it somehow reduces the fitness and survivability of Migaloo. This white color is the result of mutations in the genes that code for the proteins responsible for skin color.

Therefore, the white color of Migaloo is not most likely an advantage in its current environment.

Answer:

The dominant generation is haploid, so that the gametophyte comprises what we think of as the main plant. The opposite is true for tracheophytes (vascular plants), in which the diploid generation is dominant and the sporophyte comprises the main plant.

The term dominant generation refers with respect to plant classification and characteristics.

Dominant is something that masks the effect of others in the same condition.

In Bryophyta (non-vascular plants), the dominant generation is haploid (n), so the gametophyte consists of the main plant. The opposite is observed for Tracheophyta (vascular plants), in which the diploid (2n) generation is dominant and the sporophyte consists of the main plant.

Therefore, the term dominant generation refers with respect to plant classification and characteristics specifically.

Answer:

deoxyribose (sugar) is located between the phosphate and nitrogenous base

Answer:

A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base

Answer:

Leaching of nutrients occur.

Explanation:

NPK fertilizers are applied to the field all over the world because it has a good effect on the growth and development of plants but it has also some environmental effects such as leaching which pollutes water bodies whereas natural compost is good for the plants as well as for the soil organisms but its breakdown is very slow and it is not readily available to the plants. Lime is also very good for the soil having low pH because lime is basic in nature and it increases the pH of the soil.

Answer:

the blood gets oxygen in the lungs its called oxy-rich blood (im pretty sure this is correct)

Explanation:

Some fruits are especially well suited for DNA extractions due to their multiple sets of chromosomes. Strawberries are octoploid, which means they have eight copies of each chromosome. In comparison, human cells are diploid, which means they contain two copies of each chromosome.

Answer:

Answer:

Muscles connect to your skeleton and they contract and move the skeleton along. Your skeletal system is made up of cartilage and calcified bone that work together. They help the process of movement happen in a smoother manner. The calcified bones of your skeleton also work with the circulatory system.

Answer:

Organelles of a skeletal muscle cell contain the same organelles as other animal cells, with the addition of myofibrils. Muscle fibers within the skeletal cell are known as myofibers. These organelles allow skeletal muscle cells to contract. Skeletal muscle cells do contain more mitochondria than other cells, because muscle cells require more energy and must convert more glucose. Skeletal muscle cells also differ from other cells because of the myofilaments within the myofibrils. Within these filaments are proteins known as myosin and actin. The special filaments enable the skeletal muscles to contract. The myofibrils within skeletal muscle cells are divided into units known as sarcomeres, which are the units of skeletal muscle cell contraction.

Answer:

In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct. In cellular respiration, oxygen is used to break down glucose, releasing chemical energy and heat in the process.
