Answer:All living things are made of the same basic building blocks, cells. A human is made of 65 trillion cells. Cells are everywhere, on you skin, in your blood, and even on your tongue. In fact, your blood is clear but red blood cells are what make your blood red. Most living things are made up of many cells but some are made of only one cell, like amebas, paramecium, fungi, protists, monerans, and bacteria.
There are two basic types of cells, animal cells and plant cells. They have some common parts found in both and other parts that are unique to each. A cell membrane is found in both plant and animal cells. It is the structure that surrounds the cell and protects it. Plant cells have a cell wall, a rigid structure surrounding the cell membrane. Animal cells do not have a cell wall. Cytoplasm is the thick, jelly-like substance that makes up most of the cell. Vacuoles are fluid filled sacs in the cell. The vacuoles contain stored water or food that will be used by the cell. Cells also contain other "small organs" called organelles that carryout various cell functions. And then there is the control center of the cell, the nucleus, surrounded by a protective outer covering call the nuclear membrane. The nucleus contains the DNA, or chromosomes, that carries all the instructions on how a cell will function, live, and reproduce.
Every cell needs to energy to live and reproduce. Plant and animal cells obtain energy in different ways. Animals can not make their own food. They obtain energy by taking in food, water, and oxygen and converting it to sugar. Sugar is the only food a cell can eat. Plant cells can make their own food from water and sunlight. This process is called photosynthesis. Both plant and animal cells use energy from the food they obtain to reproduce.
All living things produce more living things. Cell reproduction is called mitosis.
Explanation:
Measure to the medial canthus of the eye
The catheter should be placed 0.5 inches into the nostril
Advance the tube until the dog coughs and then pull back slightly
Measure to the top of the head
Measure to the medial canthus of the eye
A topical anesthetic (such as proparacaine) is instilled into a nostril prior to catheter placement. The catheter is lubed and slid into the nostril and introduced into the ventral nasal meatus. It is advanced to the level of the carnassial tooth or the medial canthus of the eye and is sutured to the skin.
The given question is incomplete, the complete question is:
Demographic Transition and Clear Cutting a. The consequences of a growing human population have been a concern since the times of Thomas Malthus when he proposed that humans could exceed their carrying capacity on Earth.
i. Describe the concept of carrying capacity for a species. ii. Describe how a change in the availability of a specific resource can affect the carrying capacity of a species
Answer:
i) The maximum population of the specific species, which can be maintained within a particular environment is termed as the carrying capacity of that species. It relies upon the accessibility of water, food, shelter, habitat, and all the other resources.
ii) The defining factor of the carrying capacity of a species is the accessibility of resources. The increase in the population of a species can result in a deficiency of resources and this will eventually cause a reduction in the population of that species. Certain factors like scarcity of food, water, or even because of certain diseases the carrying capacity will reduce resulting in a reduction of the population.

Primary succession is ecological succession that begins in essentially lifeless areas, such as regions in which there is no soil or where the soil is incapable of sustaining life (because of recent lava flows, newly formed sand dunes, or rocks left from a retreating glacier).
