Nondisjunction is the failure of homologous chromosomes (chromatids) to separate properly during meiotic cell division.
Describe one way that burning rain forest trees affects nutrient cycling differently than cutting them down and leaving them on the forest floor.
Burning trees releases co₂ in the atmosphere, but cutting down trees falling on the ground nutrient returns to the land. Plants which is falling down decomposes and nutrient return to the soil.
How do trees affect the nutrient cycle?Deforestation affects the nutrient cycle because plants are the storage site of many nutrients. The nutrient cycle is interconnected with plants most of the nutrient is directly absorbed by the soil.
Plants absorb nutrients from the soil, and the animal takes nutrients from the plants, when an animal dies its body decomposes in the soil again nutrient dissolve in the soil.
Burning plants releases stores of nitrogen, carbon, and sulfur these create a loss in biodiversity and affect the nutrient cycle.
Therefore burning rainforest affects the nutrient cycle by releasing nutrient components in the atmosphere, so cutting down does not affect

In an individual heterozygous for a single trait, the probability of the recessive allele being present in a gamete is ______. Multiple choice question.
In an individual heterozygous for a single trait, the probability of the recessive allele being present in a gamete is 50 percent.
What is an Allele?
This can be referred as the variant form of a gene. In an individual heterozygous for a single trait there is the presence of the dominant and recessive allele present in the gamete.
This however means that the probability of the recessive allele will be 1/2 which is equal to 50 percent.

During metaphase I, the homologous chromosomes align at the spindle equator with each homologue Question 3 options: facing the same spindle pole. facing both spindle poles. facing opposite spindle poles. not facing either spindle pole. being separated into two sister chromatids.
During metaphase I, the homologous chromosomes align at the spindle equator with each homologue facing opposite spindle poles.
What is metaphase stage?The metaphase stage of meiosis is the stage where the chromosomes/chromatids align at the center or equator of the cell in preparation for separation.
However, in metaphase I, homologous chromosomes are aligned at the center of the cell.
Each homologous chromosome face opposite spindle poles during this stage.
Therefore, during metaphase I, the homologous chromosomes align at the spindle equator with each homologue facing opposite spindle poles.

In gel electrophoresis, how are the dna samples added to the wells?.
DNA samples are added into wells with the help of electric current because of the presence of charges.
How dna samples added to the wells?DNA samples are added into wells at one end of a gel whereas an electric current is applied to pull them through the gel. DNA fragments are negatively charged, so they move towards the positive electrode.
So we can conclude that DNA samples are added into wells with the help of electric current.

identify the selectively permeable barrier of the cell that allows certain molecules to enter and exit the cell
-A
-C
-E
-F
Answer:
Choice E.
The plasma membrane is a selectively permeable barrier which allows only certain substances to enter and exit the cell.
The selectively permeable barrier of the cell that allows certain molecules to enter and exit the cell is F, which is the cell membrane or plasma membrane.
How cell membrane is composed?The cell membrane is composed of a lipid bilayer that separates the interior of the cell from the external environment, and contains various proteins that control the movement of molecules in and out of the cell.
The cell membrane is selectively permeable, meaning it allows some molecules to pass through while preventing others from crossing.
This is essential for maintaining the internal environment of the cell and regulating the exchange of nutrients, waste products, and other substances with the outside world.

If a pea plant’s alleles for height are tt, what is true of its parents? (Select all that apply.)
Where T is tall and t is short.
- Both parents contributed a dominant allele.
- Both parents were short.
- Both parents contributed a recessive allele.
- Both parents were tall.
Answer:
Both parents contributed a recessive allele.
Both parents were short.
this is because a recessive allele will only express itself in the absence of dominant allele

Answer: there are enough available resources for the population
Explanation: the resources and the population is steady however over time the population increases in which there will be not enough resources. I hope this helped I’m doing the same thing lol :)))
In Point A, with regard to the population and resources available at that point in time, the populace has access to ample resources.
What is a population?The term “population” refers to all citizens who are either permanently residing in a country or who are just passing through. This indicator reveals how many people typically reside in a certain area.
Growth rates are the population changes that occur each year as a result of births, deaths, and net migration. The resources and the population are stable, but as the population grows, fewer resources will be available.
Populations can include but are not limited to, individuals, animals, organizations, structures, buildings, cars, farms, objects, or occasions.
Therefore, in Point A, the population has access to enough resources given the population and resources available at that time.

Evidence such as similarity in DNA make-up, embryological and anatomical similarity shows that primates share a common ancestor.
What are primates?Primates are mammals which belong to the order primates.
Primates have unique features such as:
prehensile five-digit hands and feetpossession of flat nails instead of claws acute vision with depth perception due to forward-facing eyesPrimates include man, monkeys, chimpanzee, etc.
The primates share a common ancestor as their anatomical structure are similar with hands and feet.
Embryologically, they are similar too and they share over 90% of their DNA in common.
Based on value, the DNA evidence is the most supportive of common ancestors as the DNA determines the other features of the primates.
Therefore, evidence such as similarity in DNA make-up, embryological and anatomical similarity shows that primates share a common ancestor.
