Answer:
In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Twenty-two of these pairs, called autosomes, look the same in both males and females. The 23rd pair, the sex chromosomes, differ between males and females.

Lymph capillaries Lymph capillaries filter lymph. originate as closed-ended tubes associated with blood capillary networks. cannot be discerned structurally from cardiovascular system capillaries. include layers of smooth muscle for peristalsis. concentrate lymph prior to passing it to larger lymphatic vessels.
Answer:
The correct answer is ''originate as closed-ended tubes associated with blood capillary networks.''
Explanation:
The lymphatic vessel system begins within the tissues in the form of tubes closed at one end called lymphatic capillaries (chyliferous in the intestine). These have an internal endothelial lining, similar to that of blood capillaries. These vessels are found in greater numbers in the skin, the digestive tract, and the respiratory system. The tissue fluid penetrates the lymphatic capillaries by diffusion, with the help of a small indirect pressure gradient, which gives it the arterial pressure. The walls of the lymphatic capillaries offer little resistance to the entry of substances; they are more permeable than capillaries in the blood system. The tiny capillaries form larger vessels, similar to the venules and veins of the blood vessel system. The walls are thinner than those of the veins of the blood system and its valves much more numerous.

A mom, heterozygous for type B blood, has a baby with type AB blood, what possible blood types could the baby's father have?
Select all that apply
O
A
AB
B
Answer:
A
AB
Explanation:
This question involves blood type, which can either be blood type A, B, AB or O in humans. Alleles A (iA) and B (iB) are co-dominant but dominant over allele O (i).
According to this question, a mom who is heterozygous for type B blood i.e. genotype iBi, has a baby with type AB blood. Since the mother contributed the "B" allele, it means that the father contributed the A allele. Only a father with genotype: iAi or iAiA (type A) or iAiB (type AB) can produce such allele.

Explanation:
A large population of Yellow perch lives in the East river. The Walleye is a larger fish that eats the Yellow Perch. Despite lots of prey all the Walleye have moved from the East river to a new river. What most likely caused the Walleye to move to a different river?
(A)There is a lack of food in the East river which caused the Walleye to move to a different area.
(B) The Walleye are no longer able to catch the Yellow Perch and need to move to a different area.
(C)There is climate change which has caused the resources to decline in the East river.
(D) There is pollution in the East river that the Yellow Perch are adapted to but the Walleye are not.
Answer:
(D) There is pollution in the East river that the Yellow Perch are adapted to but the Walleye are not.
Explanation:
To ensure survival and cntinurd sustenance in an environment, there is need for an animal to posses certain features which would enable her cope with the conditions of the environment. The ability of animals to successfully live and survive in an environment is made possible through adaptation as the animal's adaptive features ensures the animal is able to live through and cope. If the adaptive features aren't suitable for such environment, then migration has to occurs, leading the animal to find a more suitable environment for survival. In the scenario above, the East river was presumed to be a good habitat for the Walleye and Yellow Perch, in spite of the available and abundance of food, the Walleye migrated, which is most likely due the fact that the Walleye lack the adaptive features to survive in the East river probably due to pollution which the Yellow Perch is well adapted to.
6. How might protein synthesis execute differently if a mutation occurs?
Answer:
The wrong protein can be created or the right one with abnormal function.
Explanation:
The mutated DNA is taken through the whole protein synthesis process and translated by the rRNA and tRNA to create a protein from that new sequence.

Energy is released during chemical reactions that occur in
Answer:
Mitochondria
Explanation:
Living organisms, no matter how microscopic, require energy for their metabolic activities. However, this energy is released for use in form of ATP when the organism undergo the process of cellular respiration, a metabolic process that breaks down food to release its stored energy.
However, this cellular respiration is a chemical reaction that takes place in an organelle of an eukaryotic cell called MITOCHONDRION (plu- mitochondria).

atch the statement to the following options.A. One of a pair of chromosomes with similar genetic information and from different sources like the sperm and egg.B. Several X-shaped structures may be visible under the microscope and indicate where crossing over has occurred.C. A lattice of protein holds two replicated chromosomes in precise register with one another.D. Four chromatids are held together by a zipper-like structure.E. A process in which pairs of homologous complex chromosomes line up side by
Answer:
A. Homologue.
B. Chiasma.
C. Synaptonemal.
D. Synaptonemal.
E. Synapsis.
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
Synaptonemal complex can be defined as a network of proteins that is responsible for holding homologous chromosomes (homologues) together.
Generally, a synaptonemal complex (protein lattice) is formed between homologous chromosomes during mitosis and meiosis. Also, synaptonemal complex is important for the formation of the four sister chromatids referred to as tetrads.
Furthermore, the synaptonemal complex (protein lattice) has a tripartite structure which comprises of the following components;
I. SC protein-1 (SYCP1).
II. SC protein-2 (SYCP2).
III. SC protein-3 (SYCP3).
In conclusion, the synaptonemal complex plays a significant role in synapsis, recombination and chromosome pairing.
Matching the various terminologies in genetics with their description, we have;
A. Homologue: one of a pair of chromosomes with similar genetic information and from different sources like the sperm and egg.
B. Chiasma: several X-shaped structures may be visible under the microscope and indicate where crossing over has occurred.
C. Synaptonemal: a lattice of protein holds two replicated chromosomes in precise register with one another.
D. Synaptonemal: four chromatids are held together by a zipper-like structure.
E. Synapsis: a process in which pairs of homologous complex chromosomes line up side by side.

Explanation:
biological classification is important because it allows scientists to study organisms in a ___ way
Answer:
Systematic.
Explanation:
Biological classification is important because it allows scientists to study organisms in a systematic way.
In Science, this biological classification of living organisms based on similarities or characteristics such as eyes, number of legs, etc., is generally referred to as taxonomy.
Taxonomy can be defined as the process of naming, classification and description of living organisms such as plants and animals. The eight (8) biological classification (taxonomy) used for grouping and organizing organisms are; kingdom, domain, phylum, family, order, class, species and genus.
Hence, taxonomy helps scientist to have a good understanding and knowledge when studying various organisms.
