6) In Medieval times a ruler told the peasants that they were free to take anything from the forest that had fallen, branches, trees, leaves etc. But they were not to take any live standing trees. Within a few years the forest was dying. Why
Answer:
Due to lack of nutrients in the soil.
Explanation:
Within a few years the forest was dying because there is no nutrient is present in the soil which can trigger the growth and development of the sol. The fallen parts of trees such as branches, tree and leaves etc are decomposed by decomposers such as bacteria and fungi which turn the fallen materials into nitrogenous materials which can be used by the plant for its growth and development.

Fi
As a result of this process, offspring 1 and offspring 2 will have *
(2 Points)
Answer: A
Explanation:
they will have different traits because they will each have different dna but the same amount of genes
Offspring 1 and offspring two will have the same number of genes but different traits. So, the correct option is A.
How the same number of genes?When a sperm fertilizes an egg cell, each parent contributes 23 chromosomes with genetic information to the offspring. This means that each cell of the offspring's body has 23 chromosomes that contain instructions for their development, including their traits.What are the different traits?Parents pass on traits, such as eye color and blood type, to their offspring through their genes. Some health conditions and diseases can be passed on. Sometimes, one characteristic has many different forms. For example, blood type can be A, B, AB, or O.Eye color is based on the amount of pigment melanin in the iris. Every gene has an allele from its parents, so many variations are possible. Because of this, even if parents have blue eyes, offspring can have brown or green eyes, or one offspring can have blue, and others can have different eye colors from their family.Thus, we can conclude that two offspring will have the same genes but different alleles.

Which of the following statements is correct regarding engineering maize plants with a herbicide-resistance gene using Agrobacterium-mediated plant transformation?
a. The Ti-plasmid used for this experiment must contain tumor-inducing genes.
b. The herbicide-resistance gene is cloned into the T-DNA region of the Ti-plasmid.
c. The herbicide-resistance gene is cloned into a region outside of the T-DNA in the Ti-plasmid.
d. A guide RNA is used to transfer T-DNA from Agrobacterium to the plant cell.
e. The whole Ti-plasmid containing the herbicide-resistance gene is inserted into the maize genome after infection with Agrobacterium
Answer:
b. The herbicide-resistance gene is cloned into the T-DNA region of the Ti-plasmid.
Explanation:
Ti-plasmid has the ability to introduce part of its DNA (t-DNA) into the genome of host plants. This is very important for the relationship of genetic manipulation in maize plants, with the aim of inducing a gene that promotes herbicide resistance. In addition, T-DNA has many genes that code for the production of plant growth phytohormones, which is extremely important for the cloning process to work. In this case, we can assume that the correct answer for yours is the letter B.

6. epidermis
7. dorsal
Answer:
a. nails are a scalelike modification of the stratum corneum layer of the epidermis
b. nails form on the dorsal edges of the fingers and toes
c. fingernails do protect the digits from damage
Explanation:
The stratum corneum consists of the top layer of the epidermis (i.e., skin). Nails represent a modification of the epidermis and they are composed of densely packed dead skin cells (keratinocytes), which are rich in a protective protein called alpha-keratin. The nail plate is the hard keratinized part of the nail. The nail bed is the skin underneath the nail plate. The nails grow from the proximal portion of the nail bed, which is known as the nail matrix. The main function of the nails is to protect the tips of fingers and toes from injury.
Osmolarity tells you the concentration of solute particles in solution, osmolarity cannot always tell you the direction of water movement across a membrane.
a. True
b. False
Answer:
a. True
Explanation:
Osmolarity is a measure of solute concentration, that is, it indicates how much solute there is in a liquid. As we know, osmosis is the movement of solute across the cell membrane, where the solute passes from the more concentrated side to the less concentrated side. Osmolarity is directly linked to this concept, but it is not able to indicate the direction of movement of the solute. This is because the solute will only pass through the membrane if it is a penetrating solute. Non-penetrating solutes do not have the ability to move through the membrane, even though the osmolarity of the liquid is high.

A population has adopted an evolutionarily stable strategy (ESS) in regards to cooperation or defection. If a new mutant strategy appears that causes an opposite behavior from the norm, which of the following will result?
A. The mutant strategy will not be able to increase in numbers in the population under the influence of natural selection.
B. Antagonistic pleiotropy will allow an equilibrium in which both strategies are maintained in the population.
C. The members of the population using the original strategy will act with aggression toward those exhibiting the mutant strategy.
D. The evolutionarily stable strategy will be displaced because of natural selection in favor of the mutant strategy.
E. Natural selection will maintain the mutant strategy because the variation in strategy may be useful in future environments.
Answer:
A. The mutant strategy will not be able to increase in numbers in the population under the influence of natural selection.
Explanation:
An evolutionarily stable strategy (EES) can be defined as a strategy that is competitively superior to others strategies and cannot be replaced or invaded by any other strategy through natural selection, resulting in punishment for those who deviate from it. Thus, an EES may confer a higher reproductive/adaptive fitness than alternative strategies when it is adopted by most members of the population. Individuals having an ESS are 'spiteful' because they act not only to increase their payoffs but also to decrease the payoffs of their competitors. An EES is resistant to low levels of mutation when all individuals in the population have the same strategy. In game-theoretical terms, an ESS is a strategy such that if all the members of a population adopt this strategy, then no mutant strategies could invade the population under natural selection. In consequence, when all individuals of a population adopt an EES, mutant phenotypes cannot invade and displace the ESS.

Why do plants store their food?
Explanation:
Storing the food helps them to use it in winter and survive because there is very little sunlight available and so they photosynthesis less. When they have extra food they store it in their seeds and when the seed grows it gets it's food from the plant until the plant is able to photosynthesis and produce its food.
Answer:
The main reasons being- survival, growth and reproduction

why it is important that we have an understanding of geologic time
Answer:
Time is a very important variable in geology because the exact timing of spatially separated events allows us to reconstruct the surface and surface conditions of the ancient earth. Geologic time spans are considerably more difficult to comprehend than historical time spans because they are so incredibly long.
One reason is so that we can fully understand how geological processes that seem impossibly slow can produce anything of consequence. For example, we are familiar with the concept of driving from one major city to another: a journey of several hours at around 100 km/h. Continents move toward each other at rates of a fraction of a millimetre per day, or something in the order of 0.00000001 km/h, and yet, at this impossibly slow rate, they can move thousands of kilometres. Sediments typically accumulate at even slower rates — less than a millimetre per year — but still they are thick enough to be thrust up into monumental mountains and carved into breathtaking canyons.
Another reason is that for our survival on this planet, we need to understand issues like extinction of endangered species and anthropogenic (human-caused) climate change. Some people, who don’t understand geological time, are quick to say that the climate has changed in the past, and that what is happening now is no different. And it certainly has changed in the past. For example, from the Eocene (50 Ma) to the present day, Earth’s climate cooled by about 12°C. That’s a huge change that ranks up there with many of the important climate changes of the distant past, and yet the rate of change over that time was only 0.000024°C/century. Anthropogenic climate change has been 1.1°C over the past 100 years, and that is 45,800 times faster than the rate of natural climate change since the Eocene.

describe the effect of temperature on transpiration rate
Answer:
Temperature affects the transpiration rate in two ways. Firstly, at warmer temperatures water molecules move faster, and the rate of evaporation from stomata is therefore much faster. Secondly, the water-holding capacity of warm air is greater than that of cold air.
Explanation:
I hope it helps you
Answer:
Temperature: Transpiration rates go up as the temperature goes up, especially during the growing season, when the air is warmer due to stronger sunlight and warmer air masses. Wind and air movement: Increasing movement of the air around a plant will result in a higher transpiration rate.

How do transitional fossils help explain the evolutionary steps that took place to produce modem organisms?
Answer:
Transitional fossils show how a particular taxa accumulated adaptations to fit particular environments and/or ecological niches
Explanation:
Transitional fossils are fossilized remains of taxonomic groups/species that illustrate an evolutionary transition between a known version of a taxa/species and the current taxa/species. Transitional fossils are fundamental because they can be clearly differentiated from the ancestral group as well as of its derived descendant group. For example, there exist transitional fossils known as "mammal-like reptiles"(i.e., therapsids that gave rise to the true mammals), which are clearly different from current mammals.
Name three different cells in a leaf that contain chloroplast. Please help
The LEAF as a photosynthetic organ includes the following cells which contains CHLOROPLASTS
• the palisade mesophyll
• the spongy mesophyll and
• the stomatal guard cells
The LEAFS are the main organ of photosynthesis. Photosynthesis is the process by which green plants manufacture their food in the presence of sunlight. This takes place in the CHLOROPLASTS of these plant. CHLOROPLASTS are structures that contains chlorophyll which traps in energy from the sunlight.
The mesophyll tissues are located between the upper and the lower epidermis of the leaf. The palisade mesophyll, which is found at the upper part, contains numerous CHLOROPLASTS and is the main site of photosynthesis in the leaf.
The spongy mesophyll is located at the lower part of the epidermis. They are irregularly arranged with air spaces between them which are linked to the stomatal openings. They also contain CHLOROPLASTS.
The stomatal guard cells are a pair of bean-shaped cells which controls the opening and closing of stomata. These cells contains CHLOROPLASTS which contributes to the movement of stomata.
Therefore the three different cells of the leaf that contains CHLOROPLASTS are the palisade mesophyll, the spongy mesophyll and the stomatal guard cells.
