Answer:
Charles Darwin
Explanation:
What type of evolutionary adaptations did plants acquire to allow them to grow in areas that were not directly on a water source?
Answer:
Plants developed roots to absorb water from the ground
Answer:
Vascular seedless plants evolved specific structures to transport and hold fluids, reducing dependence on water sources.
Explanation:
If given the ability to hold on to water, the plant does not have to frow directly on a water source.

An example of a density-independent factor that affects a population's growth is Select one: a. insects eating your tomato plants. b. your tomato plants competing for water. c. a fungus infecting your tomato plants. d. frost killing all of your tomato plants. e. All answers are correct.
Answer:
The correct answer is - D. frost killing all of your tomato plants.
Explanation:
Density independent factors are the factors that are limiting factor that are affects the size of population of the living beings without being affected by density of population. In such factors density of population does not play any role or affect the size of population.
In the given option other than frost all are density dependent factors affecting size of population.

Glycolysis and gluconeogenesis are opposing pathways in that they begin or end with the same metabolites and share common intermediates and/or enzymes. Yet, for energetic reasons, the two processes cannot be the exact reverse of each other. How is this possible
Answer:
Due to difference in their products.
Explanation:
Glycolysis and gluconeogenesis are not exact reverse to each other because in glycolysis, glucose is converted into pyruvate, adenosine triphosphate (ATP), NADH, protons i.e. hydrogen ions and water whereas in gluconeogenesis, pyruvate is converted into glucose and glycogen. So due to the formation of different products of each process we can say that glycolysis is not exact reverse of gluconeogenesis.

6. What do fungi have in common with animals?
Answer:
Fungi are more like animals because they are heterotrophs, as opposed to autotrophs, like plants, that make their own food. Fungi have to obtain their food, nutrients and glucose, from outside sources. The cell walls in many species of fungi contain chitin.

Que tipo de ecosistema tienen los pingüinos emperador y Adelia?
Answer:
Los pingüinos Adelia viven en el continente antártico y en muchas pequeñas islas costeras circundantes. Pasan el invierno en alta mar en los mares que rodean el hielo antártico.
Los pingüinos emperador viven exclusivamente en entornos antárticos gélidos. Prefieren reproducirse durante el invierno, cuando el hielo se congela y se estabiliza. Estos pingüinos suelen crear colonias de reproducción en áreas cercanas a icebergs y acantilados helados, que los protegen de los peores vientos fuertes.

Answer:
Muscle cells
Explanation:
If they are paralyzed it stops use of the muscles. like... just read it bro
The cells in the prey that are most likely influenced by the poison present in the darts exist the muscle cells.
What are muscle cells?A muscle cell exists also known as a myocyte when directed to either a cardiac muscle cell or a smooth muscle cell as these exist both small cells. A skeletal muscle cell exists long and threadlike with many nuclei and is named a muscle fiber. Muscle cells originate from embryonic precursor cells named myoblasts.
The muscle cells exist as a specialized kind of cell (one of the four tissues) that can contract to exert action.
These cells (muscle cells) can be paralyzed by utilizing various inhibitors of movement such as poisons.
In conclusion, the cells in the prey that exist most likely affected by the poison present in the darts exist the muscle cells.
The cells in the prey that exist most likely influenced by the poison present in the darts exist the muscle cells.

oil-rich countries in the middle east cover about 4% of earth's total land area but posses about 48% of the world's known oil reserves. what is the main reason for high concentration of reserves in this part of the world?
The correct answer is A. Geological processes.
Explanation
Oil is a hydrocarbon of fossil origin by geological processes that transforms large amounts of organic matter deposited on anoxic bottoms of seas or lake areas of the geological past, which were later covered by heavy layers of sediment. This causes organic materials to be transformed into oil by the heat and pressure of the upper layers. However, this phenomenon does not occur in all parts of the earth because in some, as in the case of the Middle East, there were large amounts of organic matter that became an oil reserve. So the correct answer is A.
What is the function of the Xylem in a leaf?
You will create a molecular clock model for an arthropod gene. Follow these guidelines to make your model:
Your timeline will span from 90 million years ago to the present. The common ancestor in your model is an arthropod that lived 90 million years ago. The gene that you’ll track codes for a protein in the species’ venom.
The DNA sequence you’ll track contains 10 nitrogen bases. You can choose the order of the bases and where the mutations occur.
This gene mutates at a rate of approximately 0.76 base pairs every 17.1 million years. To build your model, calculate the estimated time period it takes for 1 base pair to mutate.
The first time period will only show the common ancestor. At the beginning of the second time period, three lineages will diverge from the common ancestor, each with a different mutation in their gene sequences.
The first and third descendant species will survive for the rest of the timeline. The second descendant species was extinct 50 million years ago.
Calculate how long it will take for one full base pair mutation to occur. Explain your reasoning by constructing a mathematical equation.
Answer:
The mutations occur at a rate of 0.56 base changes every 1 billion years. If this rate stays consistent, the mutation rate can be used to determine when different lineages of a particular species split
Answer:
It takes about 17.1 Million years for a base pair to mutate at a rate of 0.76 base pairs. To get the time it takes for one full mutation to occur, you must divide 17.1 to 0.76 and multiply it by 1. So, (17.1/0.76)×1=22.5. It would take about 22.5 million years for one full base pair mutation to occur. Having this being said, the first descendant with one base pair mutation would change after 22.5 million years from the common ancestor. For the second descendant, it would take 45 million years as 22.5 time 2 is 45. 5 million years later, the second descendant will become extinct while the first descendant survives. The third descendant will take about 22.5×3= 67.5 million years. Now, the first and third descendants will survive while the second descendant is extinct.

What is the difference between sediments deposited in outwash and sediments deposited in moraines?
1. Sediments in the outwash are larger.
2. Sediments in the outwash are sorted
3. Sediments in the outwash are more angular
4. Sediments in the outwash are older.
Answer:
2. Sediments in the outwash are sorted
The difference between sediments deposited in outwash and sediments deposited in moraines is that-Sediments in the outwash are sorted. Therefore, the correct option is 2.
What is the sediment of outwash and moraines?Outwash is the sediment that is carried away from a glacier by meltwater and deposited in streams and rivers. This sediment is typically well-sorted, which means that particles are relatively uniform in size, shape, and composition.
Moraines are piles of unsorted sediment that are left behind by a glacier as it retreats. This sediment is typically a mix of different particle sizes, shapes, and compositions.
The glacier's movement is not strong enough to sort the sediment of moraines, so it remains unsorted. Therefore, the correct option is 2.

what are the two characteristics of Pine due to which it is not placed under sub division angiosperms
Answer:
The angiosperms, or flowering plants, are the largest and most species-rich phylum of plants, with more than 250,000 species estimated.
Defining Characteristics
The term "angiosperm" derives from two Greek words: angeion, meaning "vessel," and sperma, meaning "seed." The angiosperms are those plants whose seeds develop within a surrounding layer of plant tissue, called the carpel, with seeds attached around the margins. This arrangement is easily seen by slicing into a tomato, for example. Collectively, carpels together with the style and stigma are termed the ovary, and these plus associated structures develop into the mature
