(A) nuclear envelope
(C) Golgi apparatus
(B) chloroplast
(D) plasma membrane
The structure that is not a part of endomembrane system is chloroplast. The correct option is B.
What is endomembrane system?The endomembrane system is a membranous component system. The membranes of the nucleus, the endoplasmic reticulum, the Golgi apparatus, lysosomes, endosomes, vesicles, and the plasma membrane are all part of it. It doesn't include mitochondrial chloroplast membranes.
The endomembrane system is a network of membranes in the cell that serve to reconfigure, transfer, and bundle proteins and lipids.
The endomembrane system is a collection of eukaryotic biological membranes and organelles that work with each other to modify, package, and transport lipids and proteins.
Thus, the correct option is B.

Answer:
their legs contain specialized hairs that are able to repel the water and to capture the air
Explanation:
The water strider is one of the most common aquatic insects. Water striders can sit on the water surface due to they have specialized hydrophobic water-repelling hairs in their legs that allow them to use the surface tension of water in order to distribute the weight. Thus, the hairs in the legs of these insects enable them to float and move on the water surface.

The element phosporus is located to the right of the element magnesium along the same period in the periodic table.
Which best describes the relationship of the elements ?
A. Magnesium has a larger atomic number
Answer: B. Phosphorus has a larger atomic mass.
C. Magnesium is in the same category as phosphorus
D. Phosphorus has similar chemical properties as magnesium
Answer:
b
Explanation:
The relationship which describes the best of the element"B. Phosphorus has a larger atomic mass."The correct option is B.
Atomic mass:
Atomic mass refers to the combined mass of protons, neutrons, and electrons in an atom.
The periodic table arranges elements in order of increasing atomic number, which corresponds to the number of protons in an atom's nucleus.
Elements in the same period (horizontal row) have the same number of electron shells, while elements in the same group or column have similar chemical properties.Phosphorus is located to the right of magnesium along the same period, indicating that it has a larger atomic number (more protons) than magnesium.Phosphorus has a larger atomic mass, while magnesium has a smaller atomic mass compared to phosphorus.Therefore, the correct option is B.

The fact that only cells are able to produce more cells is part of cell theory. The idea that organisms can develop independently of cells is called spontaneous generation, and it isn't supported by cell theory. Spontaneous generation suggests that living organisms develop from non-living matter.
Use your knowledge of relationships in a food chain, describe how a cow gets the energy it needs to survive YOU MUST USE THE WORDS sunlight, photosynthesis, producer and consumer in your answer
Answer:
All energy on Earth originally comes from the Sun. Plants use sunlight in a process called photosynthesis, to make their own food and provide energy. This is why plants are producers, because they make their own food. Cows eat plants, namely grass. So, when the cow eats the grass, the energy from the grass transfers to the cow. This is why cows are consumers, because instead of making their own food, cows, like humans, must consume their food to survive.

Which two processes allow water to enter the atmosphere?
evaporation and transpiration
precipitation and condensation
condensation and evaporation
transpiration and precipitation
Answer:
its c) condensation and evaporation
Explanation:
Evaporation and transpiration are the two processes that allow water to enter the atmosphere. The correct option is A.
What is transpiration?Transpiration is the method by which water vapor is lost via the stomata of plants. When the weather is very hot, the plant's loss of water vapor cools it down, and water from the stem and roots moves upwards or is started to pull into the leaves.
The direct impact of transpiration is that it regulates plant temperature and provides water for photosynthesis. It also transports nutrients and sugars through the plant's vascular tissues.
Evaporation is a way of vaporization that occurs on the surface of a liquid as it transitions from the liquid phase to the gas phase.
Both of these process aids to enter water into the atmosphere.
Thus, the correct option is A.

during a rainy spring, where are you most likely to find surface runoff
Answer:
there is only one surface in which we can run off in rainy season and that is room
Explanation:
steffie matt
Answer:
On a sloped parking lot
Explanation:
Surface runoff can be referred as the flow of water, that occurs when the excess water flows from the storm water, melt water, flood, rain streams and rain fall. The fast moving water current takes along with it superficial layers like surface and sub- surface layers of soil. Hence, causes water erosion of soil. The slope parking lot will favor, surface runoff more likely than in a grassy prairie, mulched flower bed, or in a sand pit because the slope will provide a surface for free flow of water. There are chances that water gets absorbed by the soil in the grassy prairie, mulched flower bed and sand pit. Whereas the slopy surface of parking lot will not allow the water retention by soil, instead will accelerate the flow of water.

Answer: Four
Fun Fact - Locusts are actually species of short-horned grasshoppers, they often gather in large swarms and can destroy entire fields of crops, because a single grasshopper can eat half its body weight in plants per day.
There are four trophic levels in the given food chain, i.e., producer, primary consumer, secondary consumer, and tertiary consumer.
What is a food chain?A food chain is a network of connections in a food web that begins with producer organisms and ends with a predator, detritivore, or decomposer species.
In the given food chain, grass is produces, grasshopper is primary consumer, frog is secondary consumer, while snake is tertiary consumer.

Given what you know about cellular organelles, what problems do you predict a cell would have if it had a defect in a lysosomal enzyme
Answer:
Cells without lysosomal enzymes will not be able to digest food and these will lead to accumulation of wastes in the cells, leading to cancerous growth and the cells will not be able to live long.
Explanation:
Lysosomes is a membrane bound organelles found in eukaryotic cells that produce lysosomal enzymes which help to breakdown or engulfs biomolecules like proteins, carbohydrates, nucleic acids, lipids it engulfs in the cells to molecules it will easily be absorbed.
Without these enzymes or defect in these enzymes, biomolecules will not be broken down and it's resultant effect is accumulation of wastes which can lead to cells destruction.
