what is traslocation
Answer:
The exchange of chromosome segment between non-homologous chromosomes is called translocation.
It is of two types:
Reciprocal translocationThere is an exchange of chromosome segments between two non- homologous chromosomes in reciprocal translocation.
Non- reciprocal translocationA part of chromosome is translocated from one non-homologous chromosomes to other so that one chromosome becomes deficient and another non-homologous chromosome gains the piece of chromosome and becomes long.

What are the characteristics of life?
All living things share a number of essential traits or abilities, such as order, environmental sensitivity or responsiveness, reproduction, growth and development, regulation, homeostasis, and energy processing. These qualities help to define life.
Reproduction: In order to be regarded as alive, an object must be able to reproduce and produce children.HeredityHeredity is the capacity of parents to transmit genetic material (DNA) to their children. This can take the shape of genotypic qualities as well as phenotypic traits, which describe how a living thing appears on the exterior.Cellular OrganizationAll living organisms are organized cellularly and are made up of one or more cells.Growth and DevelopmentAll living things grow and develop as they age, becoming more physically and psychologically mature.Adaptation Through EvolutionEvery living thing has undergone some level of evolution, and they all continue to do so in order to adapt to a constantly changing environment.Response to StimuliLiving things react to environmental stimuli.Homeostasis A living thing's capacity to maintain steady internal conditions, such as blood pressure, body temperature (thermoregulation), and water balance inside cells, is known as homeostasis.MetabolismAn organism must use chemical processes to break down and/or use materials from the environment in order to maintain its function, which is known as metabolism.

Which of the following best describes the behavior of nonconservative elements in seawater?
A. Nonconservative elements are reactive in seawater and have a long residence time.
B. Nonconservative elements are reactive in seawater and have a short residence time.
C. Nonconservative elements are non-reactive in seawater and have a short residence time.
D. Nonconservative elements are non-reactive in seawater and have a long residence time.
Answer: Option C.
Nonconservative elements are non-reactive in seawater and have a short residence time.
Explanation:
Non conservative elements are elements that enter the sea water and have little concentrations in the ocean and show spartial variationns. These elements have short residence time I .e short replacement time and they are non reactive .Constituents such as phosphate, nitrate, and other nutrients, and dissolved oxygen, carbon dioxide, etc. are non-conservative because their concentrations are later changed by chemical reaction in the sea.
is Primary Hyperaldosteronism cancer?
Primary aldosteronism is a group of disorders, originally described by JW Conn, in which there is a non-suppressible secretion of aldosterone and hypertension. Aldosterone is a salt-retaining hormone synthesized by the adrenal gland that is regulated by multiple factors, with the renin-angiotensin system and serum potassium being the major factors. Additional minor regulators include adrenocorticotropic hormone (ACTH), atrial natriuretic factor, and dopamine
Primary hyperaldosteronism can be caused by either hyperactivity in one adrenal gland (unilateral disease) or both (bilateral disease). Unilateral disease is usually caused by an aldosterone producing adenoma (benign tumor) and less commonly by adrenal cancer or hyperplasia (when the whole gland is hyperactive). Bilateral disease is usually caused by bilateral hyperplasia (when both glands are hyperactive). There are rare genetic syndromes like familial hyperaldosteronism type I and II which may cause both glands to be hyperactive.
A father produces sperm that only carry ‘t’ alleles. What is likely to be his genotype?
Answer:
The Genotype of an organism determines the genetic characteristics of an individual.
If a father produces sperm that carry only 't' alleles, the his genotype will be 'tt' or hom.ozygous genotype.
Hom.ozygous genotype contains the same type of genes responsible for a particular phenotype.
Hence, the correct answer is 'tt' or hom.ozygous genotype.

Draw a cartoon strip or write an article to summarise the greenhouse effect and how it can lead to global warming. Include the following: 1. Role of the atmosphere (greenhouse gases) in maintaining the temperature on Earth, 2. Carbon cycle between plants, animals and the atmosphere, 3. Humans burn fossil fuels, run cars and generate electricity upsetting the balance, 4. Increased amount of carbon dioxide in the atmosphere leads to increased global temperature, 5. Effects of global warming.
The greenhouse effect is an essential phenomenon for life on earth. However, human activities such as pollution and burning of fossil fuels have caused an intensification of this effect, which has harmed the atmosphere and is directly related to global warming.
The greenhouse effect is formed by a layer of atmospheric gases that settle around the planet and allows a temperature suitable for life to reach the earth's surface. Therefore, we can guarantee that this effect is essential for our survival. It is necessary that the amount of these gases is kept in equilibrium for this temperature to be constant.
However, the burning of fossil fuels, industrial activities, pollution (caused by vehicles, aerosols, fires, among others), the use of non-renewable energy releases greenhouse gases into the atmosphere daily and in large quantities.
This causes the layer of greenhouse gases that circulates the earth to become more and more expanded, not being able to disperse solar radiation easily and causing an increasing temperature. All that heat is retained in the atmosphere, thus generating global warming, which allows the planet's temperature and ocean water to increase dramatically, which can cause various harmful effects to life on the planet.
For this reason, it is necessary to carry out public policies that reduce pollution and encourage the use of clean and renewable energy that does not increase the layer of greenhouse cases, promoting well-being and life on earth.

What other adaptation could have helped koalas as they evolved from land-dwellers to tree-dwellers?
Answer:
I believe it is
fur color that closely matches the eucalyptus bark color
or B
Explanation:
My reasoning is that, if they evolved from land-dwellers to tree-dwellers, they will have almost no need for longer legs for running, as they only need strong legs and arms for climbing, not running.
The ability to communicate better doesn't really mean anything, as they are now all closer or further away, since they are all in trees now. This doesn't mean that they necessarily need to communicate better.
The ability to have several offspring at one time could be the answer, but isn't really necessary.
Predators would hunt for the koalas in the trees now, so to hide, they would need to go inside the tree trunk or camouflage themselves, which most creatures do by blending into their surroundings or changing skin color over time.

Gregor Mendel belonged to a family of farmers but he went to pursue academic studies. all these things combined with his curiosity resulted in his research studies.
Explanation:
An Austrian monk by profession, Gregor Mendel through experimental studies in his garden, discovered the basic principles of heredity. Mendel 's observations have become the basis of modern genetics and the study of heredity, and he is universally recognized as a foundation for the development of genetics. His strong will led him away from his family occupation of farming. More working in a church it was no less than a revolutionary step to choose science above faith, especially at that time.

what do scanning electron microscopes and transmission electron microscopes have in common
Answer: Both require a vacuum.
The transmission electron microscope and scanning electron microscopes are two microscopic techniques which uses a high speed and energy electron beams to create an image of the specimen. Scanning electron microscopy creates the image of the specimen by detecting reflected electrons from specimen whereas transmission electron microscopy involves transmission of electrons by the specimen. Both scanning and transmission electron microscopes require vacuum. The flow of electrons is facilitated by a chamber maintained at high vacuum. The vacuum increases the speed and energy of electrons interacting with the specimen.
