Explanation:

The chloroplast is located throughout the cytoplasm of the cells of plant leaves and other parts depending on the type of plant. Actually, you can see where in a plant the chloroplasts are because chloroplasts are what make the plant appear green.

Answer:

The chloroplast is located in the cytoplasm of the cell. Hence the location of chloroplast is throughout the cytoplasm.  

Explanation:

Cell is defined as the smallest unit of the body. It is also considered to be as building block of the body. It is present in plant as well as animal. There are many organisms that are considered to be as single-celled.

All the single celled organism are you known as prokaryotic animals and they are living on the earth for many years like thousands of years. Cytoplasm is a liquid substance which is present inside the cell. It covers all the part of the cell and all the organelles lives inside the cytoplasm.

Answer:

An inland location, because land has lower specific heat than water

Explanation:

The specific heat is a measure of how much heat must be supplied to warm up a substance by a certain number of degrees.

Water has a much higher specific heat than land, so it takes much more heat energy to heat up a given mass of water compared to the land.

To say it another way, the specific heat of land is much less than that of water, so it doesn't take as much heat energy to warm up the land.

Thus, an inland location will be relatively warmer during summers.

Final answer:

A coastal location will be relatively cooler during summers compared to an inland location, due to the higher specific heat of water which results in more moderate climate conditions along coastlines.

Explanation:

The location that will be relatively warmer during summers is a coastal location, because water has higher specific heat than land. This means that water absorbs more heat before increasing in temperature compared to land. Therefore, coastal areas tend to have more moderate climates and don't heat up as quickly as inland areas during summer. On the other hand, inland locations, because land has a lower specific heat, will experience quicker heating and thus will be relatively warmer during the hotter months.

The population decline of the Miami Blue butterfly is probably due to habitat loss, pesticide use, and climate change, similar to other butterfly species that rely on specific plants for survival.

The decline of the Miami Blue butterfly population in South Florida has likely been caused by several factors, including habitat loss due to development and construction, use of pesticides, and possibly climate change. Similar to the plight of other butterfly species like the Karner blue butterfly, which depends on the wild lupine plant for its larval development, the Miami Blue butterfly might also have specific host plants that are threatened by environmental changes. Additionally, limited availability of host plants like the butterfly weed for monarch butterflies indicates how essential specific flora is to butterfly populations.

Ecologists aim to understand the close interspecies relationships, as with the Karner blue butterfly and the wild lupine, and how factors such as wildfire suppression, which has reduced the lupine, impact the butterflies. In the case of the monarch, the focus on planting milkweeds shows the importance of preserving the plants on which butterflies rely. Examining these parallels can yield insights into the factors most likely affecting the Miami Blue butterfly.

Valves are found in veins but not in capillaries or arteries primarily due to differences in blood pressure and flow dynamics.

1. Veins experience lower blood pressure: Unlike arteries where blood is pumped directly from the heart at high pressure, veins carry blood back to the heart at lower pressure. This lower pressure can sometimes result in blood pooling, especially in the extremities where gravity works against the return flow of blood. Valves in veins prevent this pooling by ensuring that blood flows in one direction only, towards the heart, and prevents backflow.

2. Gravity and distance: Veins are often located further from the heart and may be working against gravity to return blood to the heart, especially in the lower extremities. Valves help facilitate this process by preventing blood from flowing backward due to gravity.

3. Capillaries and arteries have different functions: Capillaries are the site of exchange between blood and tissues, where nutrients, gases, and waste products are exchanged. They are very small in diameter and have thin walls optimized for this exchange. Arteries, on the other hand, carry oxygen-rich blood away from the heart to various parts of the body under high pressure. Valves are unnecessary in capillaries because blood flow is regulated by the contraction and relaxation of surrounding smooth muscle cells and the pulsatile flow generated by the heart.

Answer:

FALSE

Explanation:

Ionization energy is the minimum amount of energy required to discharge an electron from its orbital shell from an atom in ground electronic state. The closer the electron, that is to be discharged, is to the nucleus of the atom, the harder to remove it hence has high ionization energy. In addition, if the nucleus of the atoms has a higher mass and the electron is even closer, the higher the ionization energy.

Answer:

C. Capillary action and gravity

Explanation:

Capillary action lets water "stick" to the walls of the soil,  and gravity pulls it down, therfore opposing its force

Answer:

The correct answer is option C, that is, capillary action and gravity.

Explanation:

Capillary action plays an essential role in moving the water around. It is illustrated as the movement of water inside the spaces of a porous substance because of the forces of cohesion, adhesion, and surface tension.  

Capillary action takes place as water is sticky, and due to the forces of cohesion and adhesion, the molecules of water are fascinated towards each other and stick to other components. Capillary action takes place when the adhesion to the walls is robust in comparison to the cohesive forces between the molecules of the liquid. However, capillary action is restricted by the forces that work against it, that is, surface tension and gravity.  

Answer:

There would be an increase in dead matter and a lack of nutrients in the soil.

Explanation:

Decomposers break down dead matter which introduce the nutrients back into the soil.

The correct answer is A. There would be an increase in dead matter and a lack of nutrients in the soil.

Explanation:

Decomposers such as mushrooms are organisms that break apart dead matter, this is the last step or final link in a food web because decomposers break apart any death organism including top predators and they return the nutrients taken by these to the soil, which is necessary for producers or plants to exists. Due to this, if decomposers were removed dead matter would increase as this would not be broken apart by decomposers; and there would be fewer nutrients returning to the soil which would affect producers such as plants.

Answer:

When the blood becomes too acidic, the kidneys remove excess H+ ions from the body and excrete them in the urine.

Explanation:

Google

Excess hydrogen ions from an acid added to the blood are handled by the body's buffer system to maintain a stable pH level. Bicarbonate ions react chemically with these ions, forming carbonic acid which breaks down into carbon dioxide and water that the body exhales.

When an acid is introduced into the blood, it increases the concentration of hydrogen ions. These ions can be harmful if their levels become too high. The body has a mechanism in place to handle excess hydrogen ions and maintain a stable pH level. This mechanism is part of what's known as the buffer system. The blood buffer system, mainly composed of bicarbonate ions and hemoglobin, helps maintain the blood pH around 7.4. The bicarbonate ion acts as a weak base and reacts chemically with the excess hydrogen ions, forming carbonic acid which eventually breaks down into carbon dioxide and water. The body then gets rid of the carbon dioxide when we exhale.

Answer:

the five tissues that makes up this hypothetical organs are eipthelial, connective, muscle, and nervous tissue

Answer:

The five tissues, which could make up this hypothetical organ are smooth muscle tissue, stratified squamous epithelial tissue, loose connective tissue, dense irregular connective tissue, and nervous tissue.  

The stratified squamous epithelial tissue possesses the tendency to resist mechanical stresses and abrasion. It comprises of the scale-like cells that compile together in layers and provide a barrier, which is resistant to wear and tear and abrasions.  

The smooth muscle tissue possesses the tendency to contract involuntarily when instigated by the cells of the nervous system. The dense irregular connective tissue possesses the tendency to resist tension in various distinct planes of force. This is a type of connective tissue formed of collagen fibers aligned randomly.  

The loose connective tissue also called areolar tissue is made up of elastin, collagen, and reticular fibers, and ample ground components are the one tissue that glues all the other tissues together. The nerve tissue refers to a unique kind of tissue accountable for communication within the body that stimulates the contracting cells.  

Answer:

When red blood cells under a microscope are seen to have burst, it is due to a process called hemolysis. This happens when the cells are in a hypotonic solution and water rushes in excessively, causing them to swell and lyse due to the incapacity of the plasma membrane to expand further.

If you observed red blood cells under a microscope and saw that a cell had burst, this is likely due to a process called hemolysis. Hemolysis occurs when the red blood cell swells beyond what the plasma membrane can withstand. The plasma membrane has a mosaic-like structure with spaces between the molecules composing it. When a red blood cell is in a hypotonic solution, water rushes into the cell due to the higher concentration of solutes inside the cell compared to the surrounding environment. This influx of water causes the blood cell to swell, and if too much water enters, the membrane's spaces enlarge too much and the cell will lyse - burst apart.

Without control mechanisms to prevent taking on too much water, red blood cells are particularly susceptible to bursting in harshly hypotonic environments. This vulnerability is why red blood cells are often used for osmolarity studies. For instance, placing red blood cells in an environment of pure water will likely lead to hemolysis.

Answer: Multicellular organisms are larger, more efficient, and have a longer lifespan than unicellular organisms. ... The cells are specialized and must depend on each other for survival of the organism.

hope this helps :)

Explanation:

Multicellular organisms live longer due to cell complexity and organization, allowing for better adaptation and survival compared to unicellular organisms.

Multicellular organisms have specialized cells that work together to carry out functions, such as tissues, organs, and organ systems. This specialization and cooperation allow multicellular organisms to adapt to their environment and maintain internal balance, ultimately leading to a longer lifespan.

Conversely, unicellular organisms operate as individual cells and do not have the same level of complexity or organization as multicellular organisms, limiting their ability to adapt and survive in changing conditions, resulting in shorter lifespans.

Answer:

The plant cell is said to have become "turgid" i.e. swollen and hard.

brainliest plz :'D

Explanation:

Final answer:

When a plant is placed in pure distilled water, its cells will swell due to the hypotonic nature of distilled water resulting in turgidity, which is beneficial for maintaining plant structure.

Explanation:

When a plant is placed in pure distilled water, its cells will swell and become turgid. This is because pure distilled water is a hypotonic solution relative to the cells of the plant. In a hypotonic environment, water enters the cell due to osmosis, increasing the water volume inside the cell's central vacuole, resulting in turgor pressure which stiffens the cell walls. Unlike animal cells, plant cells are equipped with rigid cell walls that provide protection against bursting. When a plant cell is in a hypotonic solution, it will not burst but will instead become turgid, which is the ideal state for plant cells as it helps maintain the structure of the plant.

In contrast, when plant cells are placed in a hypertonic solution like sea water, they undergo plasmolysis, where water diffuses out of the cells causing them to shrink and the plant to wilt.

Humans influence the cycling of matter in ecosystems mainly through deforestation and pollution. Deforestation disrupts the nutrient cycle, and pollution leads to global warming, shifting the balance of ecosystems.

Humans significantly influence the cycling of matter in ecosystems in several ways. One of the primary ways is through deforestation. When humans cut down forests, it disrupts the nutrient cycle, as trees play a crucial role in absorbing carbon dioxide and releasing oxygen into the atmosphere. Another way humans impact this cycle is through pollution. For example, when industries and vehicles release carbon dioxide and other harmful gases into the atmosphere, it impacts the cycling of matter by contributing to global warming, which can change the balance of ecosystems.

Viruses are not living. They do not become alive until they attach to a cell. Viruses don't grow, and they can't make their own energy. Even though they replicate and adapt to their environment, without cells, viruses would not be able to multiply. Therefore viruses could not be classified as living.

Viruses like those causing the common cold have some characteristics of life when inside host cells but cannot perform many life processes independently. Therefore, despite the debate, they are not widely recognized as 'living organisms.'

The question revolves around the characteristics of life and whether any match the defining features of the viruses that cause the common cold. One of the central debates in biology is whether viruses are living organisms. Viruses can display many of the eight characteristics of life when they are inside a host cell. These include adaptation, evolution, and replication. However, they do not exhibit other life characteristics, such as metabolism and homeostasis.

Most critically, viruses cannot carry out most life processes outside of a host organism, unlike bacteria and other cellular organisms. Because of this, although some biologists classify viruses as 'life forms,' they are not considered 'living organisms' under the most widely accepted definition of life. Therefore, while viruses like those that cause the common cold have some life-like properties, they don't fit the full definition of a living organism.
