Animal cell organelles
Answers
Answer:
Nucleolus: Synthesis of ribosomal RNA.
Nucleus: Contains genes (chromatin).
Ribosomes: Protein synthesis.
Vesicle: Transport of materials within the cytoplasm.
Rough endoplasmic reticulum (RER): Protein synthesis.
Golgi Apparatus: Processes, packages and distributes proteins to other organelles for export.
Cytoskeleton: Structural support of cells; facilitates the movement of the organelles.
Smooth endoplasmic reticulum (SER): Lipid synthesis; drug metabolism.
Mitochondria: Produces energy for the cell called ATP.
Vacuole: Protection of the cell, collect waste products and maintain internal pH, among others. (*) Only in some animal cells.
Lysosome: Cellular digestion.
Centrosome: regulate the cell-cycle progression.
Cell membrane: separates the cell from its environment; regulates the movement of materials in and out of the cell.
Answer:
Animal Cell organelles are cell membrane, cytoplasm, lysosomes, ribosomes, a nucleus, mitochondria, the Golgi apparatus or Golgi bodies, ectoplasmic reticulum, and vacuoles.
Explanation:
You might not count the cell membrane and cytoplasm as organelles because they hold the cell together. the cytoplasm is the fluid in which the other organelles float in, and the membrane is like a fleshy crust for the cell.
Plant cells have two more organelles/structures than animal cells. They are the chloroplast and cellwall. Plant cells also have a central vacuole and maybe some few smaller ones, in contrast to animal cells with many smaller vacuoles. Vacuoles are where things the cell needs (like water) are stored.

Snapdragons, a flowering plant popular with gardeners, can have red, white, and pink colored petals. When snapdragons with red petals (RR) are crossed with snapdragons having white (WW) petals, the offspring have pink petals. The pink coloration (RW) is a phenotype in between the red and white parental phenotypes. What is this kind of inheritance pattern called?
Answers
Answer: Incomplete Dominance.
Explanation: When snapdragons with red petals (RR) are crossed with snapdragons having white (WW) petals, the offspring will have pink petals. This will make the pink coloration (RW). Since both of these genotypes are dominant it is Incomplete Dominance because the R does not completely mask the effects of a recessive allele, which in this case theres none.

Are gender traits completely a result of societal expectations?
Answers
[tex]\huge\star{\underline{\mathtt{\red{A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}}\star[/tex]
No. Gender traits in humans are largely determined by biophysical processes. There seems to be a vocal political faction that is trying to convince people in the name of liberty and equality that gender traits are completely learned, and therefore arbitrary.
But this claim disagrees with scientific evidence. In general, boys play more with cars and girls play more with dolls not because their parents are perpetuating outdated gender stereotypes, but because their brain is telling them to.
This fact does not mean that boys have to play with boy toys, or that boys who play with dolls aren't really boys. It is just a scientific observation about average behavior and its link to fetal development

Hair color and eye color are examples of discontinuous variation. The correct option is A).
What is the variation?
Variation is the difference or change in the characters or any individual. The variation in the organisms is due to genetic makeup, the genetic makeup of every individual is unique.
Discontinuous variation is where there is a limited number of variations will occur. Eye color and hair color are one of them.
Thus, option (A) discontinuous is correct regarding variation.

Mulch is divided into organic and inorganic. In both cases, it prevents the soil from drying out, weed growth and soil erosion.
Mulching is a way of mowing the grass in which the cut grass is not bought from the grass surface, but it is cut into smaller parts and scattered on the lawn, and in that way your lawn is fertilized and maintained in the right way.

Scientists have discovered that there are reproductive isolating mechanisms that can stop a population from interbreeding and possibly lead to the formation of a new species. What is this process called
Answers
Answer:
Polyploidy
Explanation:
The isolating mechanism that is capable of stopping a population from interbreeding, possibly leading to speciation is polyploidy.
Polyploidy is a condition in which a species of an organism will have multiple, instead of a diploid, chromosomal set as a result of an error during meiosis.
Non-disjunction during meiosis can make a gamete have a diploid number of chromosomes in the place of a haploid chromosome. A 2n gamete fusing with an n gamete will result in a triploid organism, 2n plus 2n gametes will result in a tetraploid organism, etc.
If the extra chromosomal set is from the same species, such polyploidy is termed autopolyploidy, otherwise, it is termed allopolyploidy. Having extra sets of chromosomes has the capacity to make an organism to be reproductively incompatible with normal diploid organisms of the same species. However, polyploid organisms can either self-pollinate or cross with another polyploid organism, a process that can lead to sympatric speciation.

Answers
Answer:
Contamination of the control sample (negative control) with DNA
Explanation:
The Polymerase Chain Reaction (PCR) is a technique widely used in molecular biology laboratories to amplify a target DNA fragment using primer pairs and DNA polymerase. In PCR experiments, it is imperative to include both positive and negative controls. The positive control refers to the amplification of a PCR product (amplicon) of known molecular size during PCR reaction in order to ensure the correct molecular weight of the target DNA fragment. The negative control refers to the inclusion of a sample without DNA in order to ensure that no contamination with DNA has occurred in the other samples.

Answers
Answer: Genes appear throughout the length of each chromosome, and each chromosome pair has a unique set of genes. ... In a diploid organism, the two corresponding genes in a chromosome pair, or alleles, might be identical or might have different base sequences. Each parent contributes one allele in each pair.Alleles are different forms of same gene. Genes are linearly arranged on chromosomes. Chromosomes contain genetic material of cell i.e. DNA. So chemically alleles, genes, chromosomes are all DNA !
