What percentage of a persons genes come from each parent?
Answer:
50% from mother 50% from father
Explanation:
Hello kassidyy00, the answer you have is correct. When a baby is consummated it will receive half of its genes from its father and half from its mother. This is due to the 22 chromosome pairings known as “autosomes” each being made up of 2 single stranded DNA segments of equal length.
Hope this helps!

Describe how X-linked traits are inherited
Answer:
X-linked recessive inheritance is a way a genetic trait or condition can be passed down from parent to child through mutations (changes) in a gene on the X chromosome. In males (who only have one X chromosome), a mutation in the copy of the gene on the single X chromosome causes the condition.
Explanation:
why are myxozoans actually a bad example of supposed evolution in action?
(I will give the best answer brainiest and extra points)
Explanation:
Myxozoans (phylum Myxozoa) are metazoan parasites utilizing invertebrate and (mainly) aquatic vertebrate hosts. They have in common with cnidarians the possession of virtually identical, highly complex organelles, namely the polar capsules in myxozoan spores, serving for attachment to new hosts and the nematocysts in surface epithelia of cnidarians, serving for food capture. Although myxozoan spores are multicellular, the simple trophic body forms of almost all species, reduced to syncytial plasmodia or single cells, reveal no clues to myxozoan ancestry or phylogenetic relationships. The myxozoan genus Buddenbrockia is one of only two known genera belonging to a clade which diverged early in the evolution of the Myxozoa. Today the Myxozoa are represented by two classes, the Myxosporea, containing all the better-known genera, which alternate between fish and annelids, and the Malacosporea, containing Buddenbrockia and Tetracapsuloides, parasitising bryozoans. The latter genus also infects salmonid fish, causing proliferative kidney disease (PKD). The enigmatic Buddenbrockia has retained some of its ancestral features in a body wall of two cell layers and a worm-like shape, maintained by four longitudinally-running muscle blocks, similar to a gutless nematode and suggestive of a bilaterian ancestry. Although some analyses of 18S rDNA sequences tend towards a cnidarian (diploblast) affinity for myxozoans, the majority of these studies place them within, or sister to, the Bilateria. The latter view is supported by their possession of central class Hox genes, so far considered to be synapomorphic for Bilateria. The simple body form is, therefore, an extreme example of simplification due to parasitism. Various hypotheses for the occurrence of identical complex organelles (nematocysts and polar capsules) in diploblast and triploblast phyla are evaluated: common ancestry, convergent evolution, gene transfer and, especially, endosymbiosis. A theory of the evolution of their digenetic life cycles is proposed, with the invertebrate as primary host and secondary acquisition of the vertebrate host serving for asexual population increase.

Which system interactions are dependent on the plant's ability to respond to the direction of light?
A
Option 1
B
Option 2
с
Option 3
D
Option 4
No
Answer:
The correct answer would be option 4
The interactions are dependent on the plant's ability to respond to the direction of light Photosynthesis.
What is Photosynthesis?Photosynthesis is essential to most life on Earth. Plants, algae, and some types of bacteria carry out the process by capturing solar energy to create oxygen (O2) and chemical energy stored in glucose (a sugar).
Consequently, herbivores get this energy from consuming plants, and carnivores get it from eating herbivores.
Plants absorb water (H2O) and carbon dioxide (CO2) from the soil and atmosphere during photosynthesis. Water is oxidized, which means it loses electrons, while carbon dioxide is reduced, which means it receives electrons, inside the plant cell.
Therefore, The interactions are dependent on the plant's ability to respond to the direction of light Photosynthesis.

Which of the following sources of electricity DOES NOT employ the use of turbines?
A
Solar
B
Wind
C. Hydro
D.
Fossil Fuels
=========================================================
Explanation:
The sources of wind, hydro, and fossil fuels all use a turbine. So we can rule out choices B,C, and D.
A turbine is basically a wheel that spins to generate motion energy into electrical energy. Think of it like one of those stationary bicycles and the bike powers up a nearby lamp (the faster you pedal, the brighter the bulb gets). Another example that's similar to a turbine would be those flashlights where you can rotate a crank to have the light come on (which is useful for when the batteries are completely dead). The windmill blades act as a giant turbine that the wind spins around. Hydroelectric turbines are spun by the falling water. Fossil fuels are burned to create very hot steam which then powers a turbine. Even nuclear power uses turbines as well. With fossil fuels and nuclear energy, the idea is to heat up a vat of water and then turn that intensely hot steam into electrical energy through a turbine.
With solar panels however, the electrical energy is converted through a process of sunlight interacting with the solar cells that doesn't require a turbine. This explains why you can use solar panels to power up devices such as phones or laptops without having any moving parts. All you need is a flat set of solar panels.
There is a slight variation of solar power known as "concentrated solar power", aka "concentrated solar thermal", where solar panels are not used. Instead, a vast array of mirrors are set up to aim the suns rays at a very specific narrow area. Think of it like a magnifying glass to focus the suns rays. The place where the narrow beam hits has a very high temperature. This high temperature heats up water to turn to steam, and the process from here is effectively the same as fossil fuels or nuclear energy. So that means turbines are involved with concentrated solar power. I'm assuming your teacher is specifically referring to solar panels when they mentioned choice A.
Which is a difference between plant and animal cells?
A) An animal cell can produce energy, because if has mitochondria.
B) A plant cell has a well defined shape, because it has a cell wall.
C) A plant cell can store genetic information, because it has a nucleus.
D) Molecules can only pass into an animal cell because it has a cell membrane.
Answer:
B. A plant cell has a well defined shape because it has a cell wall
Explanation:
When you compare an animal cell to a plant cell you can see that a plant cell has a cell wall while and animal cell only has a cell memebrane. The cell walls of the plant help the plant by providing support and keeping it's shape.
The difference between plant and animal cells is plant cell has a well defined shape, because it has a cell wall.
What are the functions of cell wall?The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress.
The main functions of the cell wall are to provide structure, support, and protection for the cell. The cell wall in plants is composed mainly of cellulose and contains three layers in many plants.
The cell wall is composed of a network of cellulose microfibrils and cross-linking glycans embedded in a highly cross-linked matrix of pectin polysaccharides.

produces genetically different offspring.
3.Meiosis is a form of asexual reproduction; mitosis is a form of sexual reproduction
4.Asexual reproduction is for plants; sexual reproduction is for animals,
answer: asexual reproduction produces genetically identical offspring; sexual reproduction produces genetically different offspring
explanation:
asexual reproduction is when a single organism uses its own DNA as a template to create another organism (through binary fission, fragmentation, budding, etc.) that is genetically identical
sexual reproduction is when two organisms create a combination of DNA (through a mixing of genes during meiosis, reproduction, etc.) to create an organism that is genetically different
