Answer:
Eukariotic cells are bigger and complex than bacteria. The difference between cystoskeleton of eukariotic and bacteria cells is the type of proetein in each one.
Explanation:
The cytoskeleton is composed mainly in arrays of protein filaments. Its function is to maintain the shape of the cell, maintain in place the organelles (such as mitochondria, nucleus, etc.) and the transport throughout the cell. Every cell has a cytoskeleton, eukaryotic, bacteria and archaea. Eukaryotic cells are bigger than bacteria and have more organelles in them to maintain in place, this is why cytoskeleton are bigger and complex. The bacteria are a single cell, simpler, with a few organelles, the cytoskeleton is more simple but important. The cytoskeleton is similar in both, the difference is the type of proteins in them. In bacteria are simple proteins, meanwhile, in eukaryotic are a complex protein.
Answer:
(A) Sex-linked dominant
(B) Sex-linked recessive
Explanation:
This type of representation is used in pedigrees that express the inheritance of sex-linked characters, that is, those that are inherited through one of the sex chromosomes, which are the X or Y chromosomes.
For this reason it is necessary to represent males and females differently in the scheme
Answer:
A) Chromosomes are made of DNA
C) Alleles are the different forms of a gene that can exist
D) Chromosomes contain genes that control the inheritance of traits.
Explanation:
Chromosomes are long molecules of deoxyribonucleic acid (DNA) that contain part (or all) of the genetic material of an organism. Humans contain 46 chromosomes organized in 23 pairs of homologous chromosomes (22 pairs of autosomal chromosomes and one pair of sex chromosomes, X and Y). Moreover, a gene is a physical segment of a chromosome that contains the information to encode a protein. Alleles are different forms of a gene (i.e., gene variants) that may be caused by mutations or genetic recombination. Humans are diploid organisms (2N: 46), and therefore we have two copies of each gene (alleles), one on each homologous chromosome.
Answer: lymphatic circulatory; respiratory
Explanation:
The autonomic nervous system controls the internal body functions and responses which are not under the voluntary control. The functions control by the autonomous nervous system are heart rate, body fluid circulation, respiration, urination, sexual arousal and pupillary response.
The lymphatic system is one of the part of the circulatory system, it consists of a network of connected tubes called as lymphatic vessels. These vessels distribute the lymph fluid throughout the body. The lymph fluid consists of white blood cells which provide immunity against the pathogen.
The respiratory system is the system which controls the exchange of gases (Carbon dioxide and oxygen) between the body and the environment.
Both lymphatic circulation and respiration are the two functions controlled by the autonomic nervous system.
Organized representation of the chromosomes within a cell.A karyotype is a(n) __________.homologsDuring sexual reproduction, each parent contributes one set of chromosomes. Members of a pair of chromosomes (one from each parent) are called __________.The chromosomes in some cells will look normal (highly compacted) but in other cells distinct chromosomes will be hard to identify.You are performing a karyotype for the first time and you forget to add the colchicine. How do you predict this will affect your karyotype?sister chromatidsWhich of the following would contain genetic material that is 100% identical?56 (14 chromosomes * 4 chromatids (per homolog pair) = 56)You are studying a diploid organism that has 14 pairs of chromosomes. How many chromatids would this cell have in G2 phase?14You are studying a diploid organism that has 14 pairs of chromosomes. How many chromatids will a gamete from this organism have?28 (14 chromosomes * 2 chromatids) = 28)You are studying a diploid organism that has 14 pairs of chromosomes. How many chromatids will a cell from this organism have in metaphase of meiosis II?S-phaseDuring this phase of the cell cycle, the sister chromatids are formed:locusThe location of a gene on a chromosome is called its _____________.anaphaseDuring this phase of the cell cycle sister chromatids separate and head towards opposite poles of the cellmetaphaseDuring this phase of the cell cycle the chromosomes line up in the center of the cell:anaphaseDuring this phase of the cell cycle the separated sister chromatids are considered independent chromosomes:diploid, haploidIn animals, somatic cells are ________ and germ cells are __________.provide a link between homologous chromosomes in meiosis.The general purpose of the synaptonemal complex is to __________.4A bivalent contains how many chromatids?chiasmaThe physical structure that is formed when two chromatids cross over is called a(n) _______.2^5If an organism has five pairs of chromosomes, how many chromosomal combinations are possible at metaphase I of meiosis?4 haploid cellsThe end result of meiosis in animals is ______.alligatorsIn a species of turtles you are studying, you find that when eggs are incubated at a low temperature, the hatched turtle will be male. Eggs incubated at a high temperature yield females, and intermediate temperatures lead to both male and female offpsring. This mode of sex determination is most similar to that inHaplo-diploidA male produced from an unfertilized haploid egg is an example of what type of sex determination system?X-linked inheritanceIf an allele is inherited on the X chromosome, but not the Y, it is said to be an example of ________.An equal number of TP and Tp gametesYou are studying a new species of plant similar to Mendel's pea plants. You are specifically interested in two genes that are located on two different chromosomes. In this plant, the gene for height has two alleles, T (tall) and t (short). The gene for leaf color has two alleles P (purple) and p (pink). What meiotic products do you expect from diploid cells that are homozyous for the tall allele and heterozygous for the purple allele?X^w+Y and X^w+X^wYou are performing a fruit fly cross similar to those that Morgan performed. Unfortunately, you forgot to write down the parents of your cross. You count the progeny, and find you have 40 red-eyed males, 80 red-eyed females, and 40 white-eyed males. Assuming that all genotypes from this cross should have equal survival rates, what are the genotypes of the parent flies?34; 17; 17<span>A dipoid organism that you are studying has 17 pairs of chromosomes. How many total chromosomes are found in a somatic cell from this organism? A sperm cell? An egg cell?</span>
