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.

What human behavior was the cause of the Nipah virus outbreak in Bangladesh? How did scientists determine this?
Answer:
Humans drinking raw date palm sap was the cause of the Nipah virus outbreak in Bangladesh. Scientists found Nipah virus in bat excretions and discovered that bats were contaminating date palm juice with their excretions (saliva, urine).
Explanation:
Nipah virus can spread to people from:
1) Direct contact with infected animals, such as bats or pigs, or their body fluids (such as blood, urine or saliva).
2) Consuming food products that have been contaminated by body fluids of infected animals (such as palm sap or fruit contaminated by an infected bat).

An ecologist is studying a newly discovered animal. The ecologist finds that it reproduces quickly and has many offspring each time it reproduces.
Which type of organism is it?
A. logistical
B. an r-strategist
C. a K-strategist
D. density dependent
THE ANSWER IS....
Answer:
B. an r-strategist
Explanation:
R-strategist (also known as r-selected species) refers to species whose population growth is based on the maximum reproductive capacity of the individuals under optimum environmental conditions (i.e., the biotic potential). These species are well known to produce numerous offspring and they show exponential population growth. The most common features of the R-selected species are 1-high reproductive rate, 2-rapid development, 3-early reproductive age, 4-small size, 5-short life spans, 6-poor competitive ability, and 7-high mortality. Some examples of r-selected species include rabbits, mice, marine invertebrates (e.g. jellyfish), weeds, bacteria, etc.
Answer:
Thanks so much for giving the answer!
It is r-stragery though.
k-stratergy produce fewer offspring slowly- such as an elephant.
r-strategey produce offsping rapidly- such as a (nasty) fly.

What family of KBOs does Orcus belong to?
Answer:
Pluto
Explanation:
Orcus is a plutino, a trans-Neptunian object that is locked in a 2:3 resonance with the ice giant Neptune, making two revolutions around the sun to every three of Neptunes. This is much as pluto, except that the phase of Orcus's orbit is opposite from Pluto's: Orcus is at aphelion when pluto is at aphelion when Pluto is at perihelion and vice versa. This was a major consideration in selecting its name, as deity Orcus was the Etruscan equivalent of the Roman Pluto, and later becamean alternate name for Pluto
Family of KBOs orcuas belongs to plutino, it is a plutino object revolves around the sun.
What is Family of KBOs?Orcus is a plutino, a trans-Neptunian object that revolves about the sun twice as often as Neptune and is locked in a 2:3 resonance with it.
This is quite similar to Pluto, but Orcus's orbital phase is the opposite of Pluto's, Orcus is at aphelion while Pluto is at perihelion, and vice versa.
This was a key factor in naming it since the deity Orcus was the Etruscan counterpart to the Roman Pluto and eventually developed into a different name for Pluto.
Therefore, revolves around the sun twice as often as Neptune is the plutino is a orcus in the family of KBOs.

When thinking about genotypes and phenotypes, which is the cause and which is the effect?
Answer:
A particular genotype does not necessarily guarantee a particular phenotype. Understanding what factors can change this expression is quite complex.. What is what i believe that above statement meant.
Explanation:
Error is the stochastic variation associated with a particular observation of the phenotype (and is managed by use of replication and and appropriate experimental design). The phenotype is the result not only of the average effect of the different alleles at a given locus across test units and across environments, but is impacted by the interaction between the different alleles and the environments (including genetic backgrounds) in which they are evaluated. Phenotype is not simply the sum of the genotype effect and the environment effect, as indicated in the mathematical formula that you provide.

Use the library and other reference materials to research lupus. Then, write a 400-word report on what you have learned. Be sure to include symptoms, causes, and treatments. Write your report in the essay box below.
if your answer is right you l get brainly
Answer:
Lupus refers to autoimmune disease in which the immune system of the body attacks its normal and healthy tissue instead of virus and bacteria. Symptoms of this disease include inflammation, swelling, and damage to the joints, skin, kidneys, heart, and lungs etc. The main cause of this disease is the environment that triggers Lupus. Chemotherapy and medications such as Nonsteroidal anti-inflammatory drugs and Antimalarial drugs etc are used for its treatment. Due to the disease's complex nature, it is often called "the of 1000 faces". In the united states there are about 16000 new cases of lupus every year. There are different kinds of lupus. This article will focus mainly on systemic lupus erythematosus (SLE), but other types include discoid, drug-induced, and neonatal lupus. Currently there is no cure for lupus, but the symptoms can be managed with care. The treatment aims to manage and prevent flare ups. The exact treatment will depend on how lupus affects the individual. Without treatment, flares can occur that may have life-threatening consequences.
