Contrast mechanical and chemical digestion.
Answer:
Chemical and mechanical digestion are the two methods your body uses to break down foods. Mechanical digestion involves physical movement to make foods smaller. Chemical digestion uses enzymes to break down food.
Explanation:
Answer:
While mechanical digestion involves physical movements, such as chewing and muscle contractions, chemical digestion uses enzymes to break down food
Explanation:
what is depolarisation
Answer:
Depolarisation refers to a sudden change in membrane
potential – usually from a (relatively) negative to positive
internal charge. In response to a signal initiated at a
dendrite, sodium channels open within the membrane of
the axon.

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.
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.

Many plants produce seeds which have small hooks on them. These hooks will attach to animals as they
move past the plants. What process do these hooks help the plant with?
A. pollination
B. fertilization
C. germination
D. seed dispersal
Answer:
A. Pollination
Explanation:
Because the "Hook" is helping the "Seed" get to other places to grow.
