Answer: 16 different gametes
ABCDABCdABcDABcdAbCDAbCdAbcDAbcdaBCDaBCdaBcDaBcdabCDabCdabcDabcdExplanation:
Gamete formation involves the random and independent segregation of alleles. During anaphase 1 (meiosis), occurs the independent separation of homologous chromosomes that migrate to opposite poles of the cell. This separation generates different chromosomal combinations in the daughter cells. There are two alternatives per homologous pair.
The number of gametes with different combinations is 2ⁿ, where
n = number of homologous pairs.
In the exposed example there are 4 pairs of chromosomes, so
the number of possible combinations of chromosomes = 2ⁿ = 2⁴ = 16
Individual: AaBbCcDdEe
You can make use of the fork line method to easily figure out the possible gametes.

What problems are experienced by fresh water and marine fish in there habitats and how they overcome it
ANSWER:
Problem faced include; habitat loss and degradation, disease outbreak, invasive species, pollution, over‐exploitation/overfishing, climate change etc.
EXPLANATION:
Problem:
Habitat loss and degradation, disease outbreak, invasive species, pollution, over‐exploitation/overfishing, and climate change are notable problems experienced by freshwater and marine fishes.
Solution:
Anthropogenic activities and stressors that rapidly threaten freshwater and marine fishes are curbed through legislation and other means to prevent extinction of fishes.
Through conservation programs that plans for individual species to more species of entire faunas of a particular location also boost population size and prevent hunting of threatened or endangered species in both realms.
Overtime, genetically modified fishes which can develop resistance to diseases are introduced to the realm.
Moreso, waste channels through which pollutants gets into the water bodies are well-treated for safety of fishes.
one of the seed banks has been storing seeds of a rare and endangered plant to keep the seeds fresh.120 of the seeds of this plant were selected to be grown out of this 120 seeds only 90 germinated
what percentage of the seeds was not fertile?show all your working
Answer:
25%
Explanation:
According to this question, a seek stored seeds of a rare and endangered plant. In order to ensure that the seeds remain fresh, 120 seeds are selected to be grown. However, out of these 120 seeds, only 90 germinated. This means that only 90 of 120 seeds are fertile.
This further means that (120-90) = 30 seeds are infertile and hence, could not germinate. In percentage, this can be represented as:
30/120 × 100
= 1/4 × 100
= 100/4
= 25% of the selected seeds are infertile.

The student hypothesizes that green pod color in pea plants is dominant and yellow pod color is recessive. Which observation would disprove this hypothesis?
Two plants with green pods produce offspring with green pods.
Two plants with yellow pods produce offspring with green pods.
Two plants with green pods produce offspring with yellow pods.
Two plants with yellow pods produce offspring with yellow pods.
Answer:
c
Explanation:
got it right on edgenu1ty
The student hypothesizes that the green pod color in pea plants is dominant and the yellow pod color is recessive. An observation that would disprove this hypothesis is that two plants with yellow pods produce offspring with green pods, which is the second option.
What is the importance of dominance?The complete dominant allele will express itself in the heterozygous condition because it will suppress the recessive allele and express itself. Here, the green is dominant over the yellow, so the green can be purebred or can have a heterozygous condition, so the green pod having a heterozygous condition can produce both the green and the yellow pods. The yellow pods are recessive, so they can only produce yellow offspring, not green offspring, as they are only expressed in the purebred recessive forms.
Hence, an observation that would disprove this hypothesis is that two plants with yellow pods produce offspring with green pods, which is the second option.

- Describe what happens to a fertilised egg cell before implantation in the uterus.
Answer:
During fertilization, the sperm and egg unite in one of the fallopian tubes to form a zygote. Then the zygote travels down the fallopian tube, where it becomes a morula. Once it reaches the uterus, the morula becomes a blastocyst. The blastocyst then burrows into the uterine lining — a process called implantation.

A graph showing the energy of the reactants and products of cellular respiration is shown here. Which description accurately compares the products and reactants of cellular respiration in terms of energy level?
Answer:
Water and carbon dioxide are products and have a lower energy level than the reactants.
In cellular respiration, water and carbon dioxide are products. According to the graph, the products have a lower energy level than their reactant counterparts.
The minimum energy is required by the element to reach the Threshold is called activation energy.
The description in the question is not given, Hence the question is incomplete.
According to the diagrams, the reactant is converted into the products when the Gibbs free energy is less than zero.

How are Earth's structures created over time?
Answer:
Earth crust is constantly changing primarily due to plate tectonics (plate motion), but it also changes from activity on the surface from river, man made and meteorite impact. ... Continents and oceans do not ride atop the plates without changing. As the plates move and change so do the continents and oceans
Answer:
Explanation:
Earth's structures were created when the planet was first formed. Over time, its own gravitational and magnetic forces drove the Earth's core rotation. Other geological activities affected its structures; such as glacial movements, tectonic plates collisions and submersion, volcanic eruptions and so on. There were also major external events the asteroid impact that killed most lives on Earth. Human activities' impact on Earth's structures were relatively small until the recent centuries.
