Which issue could cause a plant to have too little water?
O not enough soil evaporation
O not enough photosynthesis
O too much respiration
O too much transpiration
The issue could cause a plant to have too little water is not enough photosynthesis.
Most of the water that plants lose is lost through a natural process called transpiration. Plants have tiny pores holes or openings on the underside of their leaves called stomata. Plants absorb water through their roots and release it into the air as water vapor through their stomata. If the plant lacks water the leaves will turn brown and die. This also happens when the plants have too much water.
The biggest difference between the two is that too little water will make the leaves of the plant feel dry and crusty, while too much water will make the leaves soft and supple. Plants with moderate water consumption daily houseplants should be watered twice a week. Plants with low water consumption should be watered only once a week. Plants with very low water consumption need only be watered once every two weeks. Plants lose liquid water through dripping and bleeding. Moisture is discharged through pores called hidatodo.

Which of Earth's spheres are involved in the water cycle?
T A. Atmosphere, lithosphere, hydrosphere, and biosphere
B. Atmosphere, lithosphere, and hydrosphere only
C. Atmosphere and lithosphere only
D. Atmosphere, hydrosphere, and biosphere only
Explanation:
Water sustains life and is an important link between each of the four "spheres" of the Earth system (hydrosphere, atmosphere, pedosphere, biosphere)
The water cycle is the continuous movement of water on, above, and below the surface of the Earth. It is driven by the Sun's energy and involves all four of Earth's spheres: the atmosphere, the lithosphere, the hydrosphere, and the biosphere. Hence option A is correct.
The atmosphere is involved in the water cycle because it contains water vapor. Water vapor rises into the atmosphere and condenses to form clouds.
The clouds then release water back to Earth in the form of precipitation, such as rain, snow, or hail.
The lithosphere is involved in the water cycle because it contains water in the form of groundwater, lakes, rivers, and oceans.
Water evaporates from the surface of the Earth and enters the atmosphere. It then condenses to form clouds and falls back to Earth as precipitation.
The hydrosphere is involved in the water cycle because it contains all of the water on Earth.
The water in the hydrosphere is constantly moving from one place to another, through the processes of evaporation, condensation, precipitation, and runoff.
Therefore option A) Atmosphere, lithosphere, hydrosphere, and biosphere is correct.

Alfred Wegener utilized the following data to support continental drift: The fit of the continental borders across ocean basins Matching rock sequences and mountain ranges on other continents Climate evidence, like glacial deposits in regions that are currently near to the Equator
On both sides of the Atlantic Ocean, identical rocks of the same type and age can be found. Wegener claimed that once the rocks coalesced side by side, the ground gradually continent drifted apart.
The same age, rock type, and mountain ranges can be found on both sides of the Atlantic Ocean.

Stratovolcanoes – Mt. Saint Helens, WA. Fly to Mt. Saint Helens in the Cascade Range of western Washington, and then turn on the Mt. Saint Helens Contour Map overlay. The brown lines are contours (lines of equal elevations). Use the Ruler tool to determine the horizontal distance (ft) between the Problem 7 placemarks and then subtract the elevations (ft) for each placemark from the contour map to determine the relief (vertical distance). Find the slope angle of Mt. Saint Helens using the following formula (this value is representative for many composite cone volcanoes): slope angle = tan–1 (relief ÷ horizontal distance) Choose one: 5°–10° 15°–20° 25°–35° 35°–45°
Scientists have concluded that the magmatic system of Mount St. Helens has evolved from a relatively simple to a more complicated state as the volcano matured based on a thorough chemical examination of the eruptive products from each stage of volcanism.
According to the data, interaction between more mafic (basalt to andesite) and more silicic (dacite) magma batches increased from the earliest to most recent stages of Mount St. Helens volcanism. The volcano's initial eruptive phase mostly comprised of a cluster of domes encircled by an apron of tephra and debris fans of broken volcanic materials. Large portions of a center cluster of dacite domes and surrounding fans were buried by these lava flows, which sparked the cone-building process.

Your friend claims that a pyramid of biomass may not have a the same shape as a pyramid of numbers
One of the three diagrammatic representations of the ecosystem used in ecology is a pyramid of numbers. The total number of species at every level of the food chain can be seen in such a picture. Since the biomass is not taken into account, it does not necessarily have a regular pyramidal shape.
The ecological pyramids are diagrams with a pyramidal structure that explain the relationships and energy flow between various species in an ecosystem. The producers, which are the species that produce food or energy for their life, make up the lowest layer of the pyramid. Other species, known as the consumers, make up the layer above the producers and consume the producers. When a result, there is only a slight energy waste in the environment as energy moves from producers to consumers. Each level of this phenomenon's food chain is referred to as a trophic level.To know more about biomass visit:

There are a set of questions given here regarding charophytes, vaccination, virus, Pasteurization and ameboid. The answer is listed one by one below.
The group of green algae that still exists and is closest connected to contemporary land plants are the charophytes (Streptophyta, Virideplantae). The majority of algae are found in aquatic environments including lakes, ponds, and seas. Bubbles made of carbon dioxide are emitted as a result. The dough rises as a result of this. High rising cakes typically start with a light and fluffy batter, which frequently requires combining ingredients to prevent air loss.Immunization, sometimes known as vaccination, is the procedure of introducing germs into the body to fend off illnesses.Pasteurization is a procedure that uses mild heat, often to less than 100 °C (212 °F), to kill microorganisms and increase the shelf life of packaged and unpackaged foods (such milk and fruit juices). Principal Pasteurization Techniques for Milk Quickly rising temperature. High Temperature Short Time (HTST) pasteurization is the most popular technique used in the United States (HTST). Greater Heat, Shorter Time. Exceedingly high temperatures. Highly Pasteurized. Given that viruses cannot grow or reproduce on their own, they are regarded as existing somewhere in between life and non-life. Consequently, they cease to exist. But when a virus penetrates a living cell of an organism, it draws energy from the host cell and begins to procreate. An amoeba, also known as an amoeboid, is a type of cell or unicellular creature that can change its shape, typically through extending and retracting pseudopods. Amoebae are found in all major eukaryotic lineages and do not belong to a single taxonomic category. An amoeba is a protist, neither a fungus or a bacteria.
