Before Mendel's work, many hypotheses were proposed to try to explain heredity. The best known of them is that there were small animals inside the man, which were called animalcules. In man, this miniature became known as a homunculus.
What was genetics like before Mendel?The first ideas about heredity were quite simple and only claimed that children were similar to parents, without understanding the mechanism behind this finding. Genetics is the part of Biology that studies heredity, that is, the way in which characteristics are passed on from generation to generation.
With this information, we can conclude that Before Mendel's work, many hypotheses were proposed to try to explain heredity. The best known of them is that there were small animals inside the man, which were called animalcules. In man, this miniature became known as a homunculus.

Prior do the 1600s it was believed that all living things for either plants or animals. Which of these inventions led to the development of a more detailed classification system
Answer:
The Microscope
Explanation:
Before the 1600s, every living thing was a part of a two kingdom classification system derivative of binomial nomenclature. This was proposed by Linnaeus, a Swedish Naturalist, who split all living things into either the animalia or plantae kingdom. After the invention of the microscope however, a new detailed classification system was put in order to accommodate for microscopic life. This new system recognizes the existence of 6 kingdoms: eubacteria, archaebacteria, prostista, fungi, plantae, and animalia.

Which of the following will best accelerate glycogen storage after physical activity? a. a high-fat meal taken within two hours of exercise completion b. a high-carbohydrate snack within two hours of exercise completion c. a high-protein snack taken midway through exercise and another 30 minutes after exercise
Glycogen storage after physical activity will be accelerated by taking a high carbohydrate snack within two hours of exercise.
What is Glycogen?Glycogen is a polysaccharide that forms glucose after hydrolysis has taken place.
They exists as substance which are deposited in bodily tissues and serve as a store of carbohydrates.
When one consumes a high carbohydrate snack within 2 hours of exercise, muscle tissue which are spongelike will rapidly soak up glucose from the high-glycemic carbohydrates.

An example of a severe disruption to an ecosystem is (1 po O repurposing a building in a downtown area O a thunderstorm that knocks down some trees o the loss of a river system due to contamination O seasonal flooding of a river
Answer:
C
Explanation:
All of these pose major danger and disruption, but most can be fixed or don't pose long-term effects. Destroying an entire water source can cause drought or death of water-dwelling species, which can affect the other parts of the ecosystem and maybe even eliminate the whole ecosystem, if not dealt with soon enough.

All of the following is true of GMOs EXCEPT
A. They have increased food production
B. Only animals are modified genetically
C. They can increase resistance to disease
D. Many are concerned that the full impact of GMOs on people is not known
Only animals being modified genetically is not true of GMOs. Genetically
modified organisms(GMOs) usually undergo some changes to their DNA in
order to infuse beneficial trait such as size and taste, resistance to diseases
etc.
The infused trait through DNA alteration helps to increase the quality and
yield of crops thereby making them readily available for the population.
Plants and animals undergo this process and isn't restricted to animals

How does carbon dioxide concentration affect photosynthesis rate?
Answer:
An increase in the carbon dioxide concentration increases the rate at which carbon is incorporated into carbohydrate in the light-independent reaction - and so the rate of photosynthesis generally increases until limited by another factor.
Explanation:
CO2 concentration is directly proportional to rate of photosynthesis.
CO2 is raw material for process of photosynthesis.
CO2 + H2O → C6H12O6 + O2
Increase in CO2 concentration increases rate of photosynthesis.
Decrease in CO2 concentration decreases rate of photosynthesis.
Therefore, CO2 concentration is limiting factor for rate of photosynthesis.

Three gene loci, A, B, and D assort independently, and alleles A, B and D are dominant over alleles a, b, and d. What is the probability of an ABd gamete from an AABbDd individual
Following the product probability rule and assuming independence among genes, the probability of an ABd gamete from an AABbDd individual is 1/4.
What does the product probability rule state?The product probability rule allows us to calcuate the probability of occurrence of two or more events at the same time. It is about a joint probability of two or more events that might happen simultaneously, not excluding each other.
This rule is based on the dependence or independence of the events. Two events, A and B, are independent of each other if one of them does not affect the occurrence of the other one.
The rule establishes that the occurrence probability of two independent events -A and B- together is the multiplication product of the probability of occurring A by the probability of occurring B.
P(A∩B) = P(A) x P(B)
Available data:
A, B, C alleles are dominant over a, b, and c allelesThese genes assort independentlyIndividual AABbDdEach gamete will receive one of the alleles of each gene.
AA ⇒ Gametes can receive only A allele 2/2 A
Bb ⇒ Gametes can receive either B or b alleles ⇒ 1/2 B and 1/2 b
Dd ⇒ Gametes can receive either D or d alleles ⇒ 1/2 D and 1/2 d
The occurrence probability of ABd is
P(ABd) = P(A) x P(B) x P(d) = 2/2 x1/2 x 1/2 = 2/8 = 1/4.
The probability of an ABd gamete from an AABbDd individual is 1/4.

In the trophic system, herbivores are referred to as “primary consumers” since they are the first animals to consume producers. They are also the carriers of photosynthetic energy. Thus, option C is correct.
What is herbivore?
An animal that has evolved physically and physiologically to eat primarily plant matter, such as foliage or marine algae, is called a herbivore.
Herbivorous animals often have mouth parts adapted to rasping or grinding due to their diet of plants.
An animal or insect that only consumes plant material, such as grasses, fruits, leaves, vegetables, roots, and bulbs, is known as a herbivore.
Only living creatures that require photosynthesis are consumed by herbivores. Insects, spiders, fish, and other creatures are not included in this.
Therefore, herbivores are referred to as “primary consumers”
