Climate, topography, and geological age contribute to higher biodiversity in tropical regions compared to temperate and polar regions.
The factor that affects biodiversity and explains why temperate and polar regions have less biodiversity than tropical regions is linked to climate, topography, and geological age. Tropical regions are more diverse due to the complexity of environments they provide, which promotes genetic isolation and speciation. Other significant factors influencing biodiversity include habitat destruction, climate change, pollution, invasive species, and over-harvesting.
Climate change is both a cause and a consequence of biodiversity loss, affecting genetic, species, and ecosystem levels. This change can lead to alterations in hydrological cycles, affecting water sources, and amplify land degradation. Factors like geological age and complexity offer environmental variation that, given time, allow for opportunities in local adaptation and speciation.

Refer to the figure showing a pedigree of a family affected by a sex-linked recessive disorder. If a female is a carrier for a sex-linked recessive disorder, is it possible for her sons to be unaffected by the disorder? Choose the best answer and explanation.
A. Yes, this is possible. Males receive an X chromosome from their mother. If their mother is a carrier, a male has a 50 percent chance of being affected by the disease and a 50 percent chance of being unaffected.
B. No, this isn't possible. If a mother is a carrier of an X-linked recessive disorder, her sons will be affected by the disease and her daughters will be carriers of the disease.
C. No, this isn't possible. X-linked recessive disorders can't "skip" generations like other genetic disorders.
D. Yes, this is possible. Males receive an X chromosome from their mother. If their mother is a carrier, the mutated X chromosome won't be passed on to sons and so they'll be unaffected.
Answer:
A
Explanation:
Answer:
The correct answer is option A.
Explanation:
If a particular woman is a carrier (XhXH) for a sex-linked disease that means she has one copy of the recessive gene on X-chromosome(Xh) and one copy of the dominant gene on X- chromosome (XH).
For a male offspring of a carrier mother to not get affected by a sex-linked disorder there are 50 percent chances if his father is not affected. In this case, Male offspring receive an X chromosome only from mother. So it could be Xh or XH so this offspring has a 50% chance of being affected or unaffected.
Thus, the correct answer is option A.
Volume is a three dimensional space and is measured using A) single units B) squared units C) cubed units D) Linear units
Answer:
C) cubed units
Explanation:
Volume, accounting for length, width, and height, is measured using cubed units. The standard unit is the cubic meter (m³), and a commonly used unit is the liter (L), equivalent to a cubic decimeter (dm³). Understanding of dimensions is vital for dimensional analysis.
Explanation:Volume is a measure of the amount of space that an object occupies or that is enclosed within a container. So, when we measure volume, it needs to account for all three dimensions: length, width, and height. Therefore, volume is measured using C) cubed units.
For instance, the standard International System of Units (SI unit) of volume is a cubic meter (m³). This is based on the base unit of length and is the volume that would be occupied by a cube with edges of precisely one meter in length. The more commonly used unit for everyday quantities of volume is the liter (L), which is equivalent to one cubic decimeter (dm³).
Understanding how dimensions relate to the units we use to measure physical quantities is a crucial part of dimensional analysis. This process ensures the mathematical relationships and conversions between different units are valid.

Aragonite shells of clams, snails, or scleractinian corals may be preserved unaltered in Cenozoic deposits, but they are generally dissolved or recrystallized in older deposits.
TRUE or FALSE
Answer:
The above statement is true.
Explanation:
The shells of aragonite are affected by various ongoing earth dynamic processes, such as physical and chemical weathering and erosion of the rock layers that contain these fossils, chemical reactions between fossils and acid water dissolving the materials of the shells.
The older Paleozoic and Mesozoic rocks have undergone significant changes with increasing time due to the effects of events such as tectonism, volcanism, erosion and so on. So the fossils present in these rocks were affected and were altered. But the rocks of the Cenozoic era are of recent age, about 65-60 million years old. During this era, massive deposition of sediments has taken place throughout the globe which provides a suitable condition for the preservation of fossils like aragonite shells. So these fossils found in these deposits are not much altered.

Which of the plant-like protists are multicellular ?
Multicellular plant-like protists include seaweed and kelp, which perform photosynthesis like plants but do not have true stems, roots, or leaves. Kelp can grow exceptionally large and forms underwater forests, serving an essential role in marine ecosystems.
Explanation:Among the plant-like protists, the ones that are multicellular include seaweed and kelp. These organisms are akin to plants in that they also contain chlorophyll and perform photosynthesis to create their own food. However, they differ from plants as they do not have true stems, roots, or leaves and lack cellular specialization or differentiation into tissues.
Examples of multicellular, plant-like protists are seaweed, kelp, and other forms of green, red, and brown algae. Kelp is particularly noteworthy because it can grow over 100 meters long and forms vast underwater 'forests.' Although most protists are microscopic and unicellular, these multicellular protists display the enormous diversity in size and form that exists within the protist kingdom.
Predict the effect of a plant disease that
destroys all the chloroplasts in a plant.
Answer:
the plant will die
Explanation:
If a plant disease destroys all of a plant's chloroplasts, then it would be detrimental for the plant and for all of the animal kingdom, as animals depend on the plant for food and for oxygen.
What is the role of the plants?Plants are the producers of the ecosystem that produces oxygen for itself and for all the animals, along with glucose. The chloroplast is the plant organelle that has thylakoids and stroma; in the thylakoids, water hydrolysis takes place and ATP is released, and in the stroma, carbon dioxide is fixed to form glucose. If these do not occur, the plant will be unable to produce all of them. Without the chloroplast and without food, they will perish.
Hence If a plant disease destroys all of a plant's chloroplasts, then it would be detrimental for the plant and for all of the animal kingdom, as animals depend on the plant for food and for oxygen.

Match the types of competition to their descriptions
So the 1st description is interspecific competition
2nd one is intraspecific competition
3rd one is interference
4th one is exploitation
Competition can be primarily categorized into perfect and monopolistic types with both showing demand elasticity in the long-run. Perfect competition has a perfectly elastic demand curve, while monopolistic competition has a demand curve that is not perfectly elastic, allowing some leeway in pricing.
Explanation:Types of Market Competition
Competition in economic markets can be categorized into different types which have distinct characteristics. The main types are perfect competition and monopolistic competition. In both cases, in the long-run, consumers are sensitive to price changes, which signifies demand elasticity. However, they differ in how firms face the price-demand relationship. Perfectly competitive markets feature perfectly elastic demand curves, meaning any price increase could eliminate demand for a product. Conversely, monopolistic competition presents a not perfectly elastic demand curve; firms have some market power to raise prices without losing all customers.
Key Comparisons and Concepts
Perfect competition serves as a theoretical benchmark to evaluate other market structures, which include monopolistic, oligopoly, and monopoly competetion. The amount of competition in a market impacts prices, as well as the demand and supply of goods and services. Moreover, exploring the evolutionary effects of intraspecific (within a species) and interspecific (between different species) competition can provide insights into how competition influences performance and survival strategies in biological ecosystems.
Species can vary in several ways. Which of the following is one of Darwin's ideas that was accepted by most scientists of his time due to the large number of fossils being discovered at that time?
A. Species vary around the world.
B. Species have specific adaptations to their local environment.
C. Species that live in seawater can also live on mountains.
D. Species change over long periods of time.
Answer:
B. Species change over long periods of time
Explanation:
Darwin was a revolutionary scientist in the field of biology and evolution. He managed to notice that the animals are changing over time, and that one species can become much different over time because of the changes in its environment. The theory of Darwin was that the species change in accordance to their environment, thus they develop advantageous traits so that they can be more competitive. As there were lot of fossils found in this period of time, so there was a lot to compare with, great deal of scientists accepted Darwin's theory, though they had lot of criticism for some other theories of his.
Answer:
D. Species change over long periods of time.
