Science Seminar Question: What was the main cause of the decrease in the size of the orange-bellied parrot population? The population decreased because... Claim 1: births decreased. Claim 2: deaths increased.
Answers
Answer:
The population has decreased because the number of live births has decreased.
The evidence suggests that the population has decreased because of the lack of food availability and resource population due inappropriate management of habitat. The parrots losing their resource population has affected the reproduction cycles of the breeding females causing lower live births in these parrots.
Climate change also should be taken into account, with the everyday change in the climate it makes for migration to populated breeding grounds unmanageable. If this proves to be the case then an artificial climate controlled sanctuary may be one of the last hopes to saving this breed on parrot.
Based on the evidence, I conclude that improving or creating an ecosystem where the food resources are plentiful and the climate was sustainable would increase the breeding of the animal.

Question 4:Protons are a type of subatomic particle with a positive charge. ... Protons and neutrons have approximately the same mass, but they are both much more massive than electrons (approximately 2,000 times as massive as an electron). The positive charge on a proton is equal in magnitude to the negative charge on an electron
Question 5:Atoms are the basic building blocks of ordinary matter. Atoms can join together to form molecules, which in turn form most of the objects around you. ... The protons and neutrons cluster together in the central part of the atom, called the nucleus, and the electrons 'orbit' the nucleus.
Question6:Thomson's model of the atom in 1897 shows that the atom was a sphere of matter, wherein the electrons are mixed inside it. This model does not show the protons and the neurons. On the contrary, the current model that was proposed by Niels Bohr gives us a clearer representation of the structure of an atom.

5. Albinism is a failure to produce the enzyme needed to make melanin. It is recessive to normal pigmentation. An albino woman whose father is albino and mother normal, marries a normal man, one of whose parents is normal and the other albino. He has an albino sister. The couple have a normal daughter. Identify all genotypes and phenotypes. What is the probability of a heterozygous dominant parent and a recessive parent having an affected boy if a particular trait is autosomal recessive?
Answers
The genotypes that are involved are AA and aa
The probability of a hete--rozygous dominant parent and a recessive parent having an affected boy if a particular trait is autosomal recessive is 50%
What is albinism?We can infer that the daughter must have the genotype Aa given that the dominant allele (A) is required for normal pigmentation and the couple has a daughter who is normal.
Let's think about the following in relation to the second query concerning the likelihood of an affected boy having het---erozygous dominant parent (Aa) and a recessive parent (aa) if the trait is autosomal recessive:
The affected boy would need both copies of the recessive gene (aa) if the characteristic is autosomal recessive in order to display it.

In deducing the evolutionary relationships among dogs, do you think it would be better to use a sequence that is neutral or one that is under selection? Explain your answer
Answers
Answer:
a neutral marker
Explanation:
A gene polymorphism can be defined as the existence of two or more variants of the same gene (i.e., alleles). A polymorphism may be a difference of one nucleotide base in DNA (single nucleotide polymorphisms, SNPs) or indels (i.e., insertions and deletions). A gene under selection will have many polymorphisms in its sequence which may lead to convergence and disproportionate divergence among sequences, and thereby will be uninformative to trace the evolutionary history among individuals within a species, population, etc. Conversely, neutral molecular markers exhibit fewer nucleotide differences, it is for that reason that they are commonly used to determine genetic population structure among individuals.

Explain homeostatic mechanism can conserve oxygen in diving animals
Answers
The mechanism to conserve oxygen in diving animal is diving reflex.
What is homeostatic mechanism?
Homeostasis is a system property that regulates variables so that internal circumstances stay steady and largely constant. Homeostasis can be seen in the regulation of body temperature and the balance of acidity and alkalinity.
Homeostatic regulation refers to the adjustment of physiological systems within the body and consists of three elements or mechanisms: (1) the receptor, (2) the control center, and (3) the effector.
What is diving reflex?
The diving reflex is a clever physiological mechanism that allows the body to manage and tolerate low oxygen levels. During the diving response, oxygen consumption is reduced via energy-efficient swimming or gliding behavior, as well as modulation of metabolism, heart rate, and peripheral vasoconstriction.

put the following statements in order to explain the process of acid-base regulation by the kidney, starting with the decrease in blood ph.
Answers
The process of acid-base regulation by the kidney begins with a decrease in blood pH. This leads to an increase in the amount of carbon dioxide (CO2) in the blood.
The Na+ and bicarbonate ions are then transported into the interstitial fluid and diffuse into the blood. In the blood, the bicarbonate ions combine with the excess H+ ions, which increases the blood pH and helps to restore acid-base balance. This process is a critical mechanism for maintaining properblood pH levels in the body and preventing acidosis or alkalosis.
Blood pH decreases.CO2 diffuses into the kidney tubule cells.The carbonic acid-bicarbonate equation is driven to the right, forming H+ and HCO3-.H+ is secreted into the filtrate in exchange for Na+.Na+ and bicarbonate are symported into the interstitial fluid and diffuse into the blood.In the blood, bicarbonate ions are combined with H+ to increase the blood pH.which diffuses into the kidney tubule cells.

Answers
To answer this question we need to analyze each statement.
The members are geographically isolated from each other. This is not correct, because if each member is isolated there would be no reproduction and the population would be extinct in a generation period.
The members are reproductively isolated from each other. This is not correct as it would happen a very similar scenario depicted in the previous statement.
The members are genetically identical to each other. This is not correct as the majority of populations seek out outcrossing, this scenario occurs very rarely in some plants that self-pollinate however is not common.
The members are all of the same species. This statement is correct as populations are composed of organisms belonging to the same species, when we have several species or populations we are talking of communities.

The biome that fits this description is the Savannah. It is characterized by grassy plains with scattered trees and is home to large herbivores like zebras, who use their herd and stripes as a defense mechanism against predators.
So, the correct answer is C (Savannah).
What are herbivores?
Herbivores are animals that primarily feed on plants, such as leaves, stems, roots, fruits, and seeds. They have specialized digestive systems that are adapted to break down the complex cellulose found in plant cell walls into usable nutrients, such as carbohydrates and proteins. Examples of herbivores include cows, horses, rabbits, deer, and many species of insects, such as butterflies and grasshoppers.
The biome that is home to large herbivores who travel in herds to evade predators and where some animals, like zebras, use their herd and stripes to confuse predators is the Savannah. This biome is characterized by grassy plains with scattered trees and is found in tropical regions. The savannah is home to many large herbivorous mammals such as elephants, giraffes, and antelopes, who form herds for protection against predators like lions, cheetahs, and hyenas. The stripes on zebras' coats help to confuse predators by making it difficult for them to pick out a single target from the herd.
