Answer:

D. A positive charge, because of a covalent bond with oxygen

Explanation:

A water molecule contain both hydrogen and oxygen atom. Water is a polar molecule because it has positive electric charge in one of it's poles and negative charge on the other. The hydrogen is positively charged and the oxygen is negatively charged which are bonded by covalent bond. Hydrogen is positively charged because it cannot attract electrons strongly like oxygen which is positively charged. There is unequal sharing of electrons in water molecules and this is why oxygen is slightly negative and hydrogen is slightly positive.

Why is convection more important than conduction in the troposphere? Halp lol
MAVERICK [17]

Answer:

The faster the particles are moving, the more energy they have. Why is convection more important than conduction in the troposphere? The air doesn't conduct heat well so only the first few meters of the troposphere are heated with conduction

categorize the following characteristics based on whether they are describing chloroplasts or mitochondria.
Ghella [55]

The categorization of the characteristics based on whether they are describing chloroplasts or mitochondria are as follows:

  1. <u>Mitochondria:</u> carry out cellular respiration.
  2. <u>Chloroplasts:</u> carry out photosynthesis.
  3. <u>Mitochondria:</u> found in plant and animal cells.
  4. <u>Chloroplasts:</u> produce carbohydrates used as source of food for most living things.  
  5. <u>Mitochondria:</u> abundant in human muscle cells.
  6. <u>Chloroplasts:</u> not found in animal cells.
  7. <u>Chloroplasts:</u> contain chlorophyll.

<h3>What is a cell?</h3>

A cell can be defined as the fundamental functional, structural and smallest unit of life, which is found within the body of an organism.

Some examples of cell organelles that are found in the body of an organism include the following:

  • Mitochondria.
  • Nucleus.
  • Endoplasmic reticulum (ER).
  • Vesicles.
  • Cytoplasm.
  • Cell membrane.
  • Chromosome.
  • Golgi apparatus (bodies).
  • Chloroplast

<h3>What is mitochondria?</h3>

Mitochondria can be defined as one of the cell organelles that is found in the body of a living organism.

Also, mitochondria is known as the powerhouse because it is saddled with responsibility of providing all the energy required in the cell, especially by transforming energy forms through series of chemical reactions.

Where do queen bees lay eggs and larval bees are fed by worker bees
steposvetlana [31]

Answer:

1. Queen bees lay their eggs after within each cell inside a honeycomb.

2. True. Worker bees feed the larvae with a combination of nutrients, from nectar and pollen to bee milk and water.

Explanation:

1. Queen bees lay their eggs after within each cell inside a honeycomb (hive) <em>[</em><u><em>See image below]</em></u><em> </em>during the winter.

The queen is able to lay over two thousand eggs PER DAY! Each egg has an approximate size of 1 mm long. This process then leads to the formation of a whole new colony of bees.

<u><em></em></u>

2. True.

Worker bees have the largest density of all, that is, there are numerous worker bees within a colony. As their name "worker" implies, they have plenty of tasks to perform. For example, they have to clean the hive regularly, ventilate it during warm conditions or keep it warm during cold conditions, and also care for the queen. However, one the most important roles of workers is to feed the larvae, during this stage they are also called "nurse bees." These bees feed the young with a combination of nutrients, from <u>nectar and pollen to bee milk and water</u>.

Which of the following is most likely to decrease biodiversity?
frez [133]

Answer:

Add native plants to a suburban garden because you are adding already flourishing wildlife

Sea Urchins are primary consumers because they eat the kelp

Sun -> Grass -> Rabbit because grass lives off of photosynthesis from the sun and rabbit eats the grass

I think there would be more biomass in grass because there is a lot more spread throughout the savannah while elephants are way bigger there is less of them.
