Hi, you've asked an incomplete question. The missing options read;
a. 1/6
b. 1/9
c. 1/18
d. 1/36
e. none of these choices
Answer:
e. none of these choices
Explanation:
Remember, someone with an h.o.m.o.z.y.g.o.u.s gene basically inherits two identical alleles; one from their biological mother and the other their biological father.
In this scenario, the real concern should be to determine the probability that the girl child inherits a dominant allele that contains the gene that causes albinism. Hence, since there's little information about the gene type of the parents, a concise assumption can be made, thus rendering the listed options unlikely.
New combinations of DNA can be formed from several sources in the
genetic material passed from parents to offspring including mutations
caused by environmental factors, errors during replication, and meiosis.
Choose one of the above factors and describe how it specifically leads to a
new combination of DNA.
Your answer
Meiosis is the common factor which is responsible for the production of new combinations or recombination in the organisms which reproduce through sexual mode of reproduction.
What is Meiosis?Meiosis is a special type of cell division which occurs in the germ cells in organisms which reproduce through sexual mode of reproduction. These organisms produce the gametes, such as sperms or egg cells. Meiosis involves two rounds of division which ultimately result into formation of four daughter cells with only one copy of each chromosome.
Recombination or new combination results when two molecules of DNA exchange pieces of their genetic material with each other. One of the most common examples of recombination can be observed during meiosis specifically, during the prophase I stage, when homologous chromosomes line up in pairs and swap some segments of their DNA.

Osmosis is the passive transport of what substance
Answer:
Osmosis is the passive transport of water molecules across a selectively permeable membrane. In osmosis, water moves from an area of high concentration (high water potential) to an area of low concentration (low water potential) in order to balance out the concentration on both sides of the membrane. This process can be observed in living cells, where the membrane surrounds the cell controls the flow of water and other molecules in and out of the cell.
In simple words, Osmosis is a type of diffusion that specifically refers to the movement of solvent molecules through a selectively permeable membrane. It is a fundamental concept in biology and is crucial for the proper functioning of cells and organisms.

Proteins themselves are major structural elements of cells.
Bio molecules are related to the cell cycle such that they partake in the
numerous activities such as cell division that occur in cell cycle.
Bio molecules such as DNA and RNA store the genetic traits of the
organism. These traits are usually passed to the offspring during cell division
in the cell cycle. DNA contains other bio molecules such as protein which
forms the base pairs.
Cell division such as meiosis gives rise to four unique daughter cells and
mitosis gives rise to two identical cells. The bio molecules basically assist in
the passing of traits to their offspring.

1. What other process can you think of that is similar to the journey of a signal through the neuron? For
example, a relay race can be similar to a neuron passing the baton to another neuron. Think of another
example and explain how.
Neurons are similar to other cells in body because: Neurons are surrounded by cell membrane. Neurons have nucleus that contains genes. It contain cytoplasm, mitochondria and other organelles.
what are neural signals?
Information from one neuron flows to another neuron across small gap called a synapse (SIN-aps). At synapse, electrical signals are translated into chemical signals in order to cross the gap. Once on other side, the signal becomes electrical again.
The transfer of information from neuron to neuron takes place through release of chemical substances into the space between axon and the dendrites. These chemicals are called neurotransmitters, and process is called neurotransmission. The space between the axon and dendrites is called the synapse
Neurotransmitter release from presynaptic terminal consists of a series of intricate steps:
1) depolarization of the terminal membrane
2) activation of voltage-gated Ca2+ channels
3) Ca2+ entry
4) a change in conformation of docking proteins
5) fusion of the vesicle to the plasma membrane

Select
groups.
Between three and eight carbon atoms can be found in a monosaccharide, although only those with five (pentoses) and six (hexoses) are typically seen in nature.
What are the monosaccharides?The most prevalent monosaccharide is glucose, often known as dextrose or blood sugar. However, glucose accounts for a very minor portion of the total carbohydrates in a regular diet.
The majority of the time, glucose is only consumed when it is joined with other sugars to form a poly- or disaccharide.
The three monosaccharides that are most prevalent are glucose, fructose, and galactose. The monosaccharide category also comprises sugar alcohols and pentoses in addition to these three sugars.
Therefore, monosaccharides have a backbone of five or six carbon atoms.

What animals have been dominant in the Cenozoic era
Explanation:
Cave lions, sabre-toothed cats, cave bears, giant deer, woolly rhinoceroses, and woolly mammoths were prevailing species of the Quaternary period. Without the dinosaurs, plant life had an opportunity to flourish during the Cenozoic era.
The Quaternary period was dominated by cave lions, saber-toothed cats, cave bears, giant deer, woolly rhinoceroses, and woolly mammoths. Plant life had a chance to thrive during the Cenozoic era without the dinosaurs.
What are the characteristics of Cenozoic era?From the Cenozoic period nearly 66 million years ago to the present day, life is considered recent.
Plants and animals look the one most like they do today during this time period.
The Cenozoic Era is divided into even smaller periods known as Epochs, so there will be even more guideposts in this Era.
Because of the extinction of many groups of giant mammals during the Cenozoic era, smaller species were able to thrive and diversify because their predators no longer existed.
Thus, big cats, saber-toothed cats, cave bears, giant deer, woolly rhinoceroses, and woolly mammoths monopolized the Quaternary period.
Plant life had a chance to thrive without the dinosaurs during the Cenozoic era.

Which statement correctly describes the flow of energy in photosynthesis?
Answer:
DPhotosynthesis stores energy because energy is released when glucose is formed from carbon dioxide and water. The passage describes a condition that is inherited.
Energy from the Sun flows into plants through photosynthesis, which is also known as “putting together with light,” and eventually into humankind. In the end, humans are powered by the Sun's energy to eat and survive. Thus, option D is correct.
What describes the flow of energy in photosynthesis?Solar energy is converted into chemical energy during photosynthesis, which produces glucose from water and carbon dioxide. The by-product is the emission of oxygen. In the process of breaking down glucose during cellular respiration, oxygen is consumed, which also produces heat and chemical energy.
Photosynthesis is the tremendous energy flow that underlies electricity and is the foundation of all life. Whether we are vegetarians or not, we joyfully devour our food without giving the basic mechanism that provides us with this gift even the least thought.
