The answer is
"cells".
The simple difference between unicellular and multicellular organisms is that unicellular organisms consist of only one cell as opposed to
multicellular organisms which are composed of multiple cells. Unicellular
organisms are mostly not seen by human eye (though there are some which can be
seen), one need to use a microscope to see them.

Evidence that Earth’s core has a high iron content comes from the study of _____.
Evidence that Earth’s core has a high iron content comes from the study of "meteorites".
Meteorites refers to the pieces of different bodies in our solar system that make it to the ground when a meteor or "falling star" flashes through our climate at velocities of 15 to 70 kilometers for each second (approximately 32,000 to 150,000 miles for every hour). The larger part begin from space rocks broken by contacts with different space rocks. In a couple of cases they originate from the Moon and, apparently, comets and the planet Mars. Shooting stars that are found after a brilliant occasion has been seen are known as a "fall," while those found by chance are known as a "discover." Meteorites are normally named after a town or an expansive geographic milestone nearest to the fall or find, aggregately named regions. "Meteorite" can allude to an individual example, to those gathered inside a strewnfield, or to a particular territory.

A biology student wants to conduct a study of how the amount of sunlight affects the length of sleep for mice. she sets up for cages with a mouse in each cage. what are the constants? what is the independent variable? what is the dependent variable? what data do you need to collect during this experiment?
In the biology student's experiment, the constants include the cage environment and mice care conditions. The amount of sunlight is the independent variable, while the sleep length for the mice is the dependent variable. They must collect data on sunlight exposure and sleep length.
Variables in a Biology Experiment
When a biology student conducts an experiment to study the effects of sunlight on the length of sleep for mice, several components must be identified. The constants are the conditions kept the same across the experiment, such as the type of mouse, the environment within the cages aside from varying light, the mice's diet, and other care conditions.
The independent variable is the amount of sunlight that the mice are exposed to, as it is the condition being manipulated or changed. The dependent variable is the length of sleep for the mice, which is the observed outcome that may change in response to alterations in the independent variable.
To collect relevant data during the experiment, one needs to record the exact amount of sunlight each mouse receives (which potentially could be measured in hours of exposure or intensity of light) and the length of sleep for each mouse, quantified in hours or minutes of sleep.

In order for the growth rate to remain constant what must happen to the birth rate?
Final answer:
To maintain a constant growth rate, the birth rate must be equal to the death rate, achieving a balance where the population size remains stable. This scenario is typically reached in Stage 4 of population growth dynamics, where both birth and death rates are low, hence no significant change in population size occurs.
Explanation:
In order for the growth rate to remain constant, the birth rate must be equal to the death rate. This balance ensures that the population size stays stable over time. Population growth dynamics can be understood through different stages:
Stage 1 - High birth and death rates lead to slow population growth.Stage 2 - The death rate falls but the birth rate remains high, leading to faster population growth.Stage 3 - The birth rate starts to fall, slowing the population growth.Stage 4 - The birth rate and death rate reach the same low level, resulting in zero population growth.At Stage 4, the key to maintaining a constant growth rate, which is essentially zero growth in this context, is having the birth rate decrease to match the lower death rate. This equilibrium prevents any significant increase or decrease in the total population size. Factors such as societal development, healthcare improvements, and policies like the One-Child Policy in China have been historical influencers on birth and death rates, affecting population stability.
which of the following terms can be defined as the movement of water across a cell membrane?
a- exocytosis
b-osmosis
c-active tranport
d-facilitated diffusion
Answer:
b-osmosis
Explanation:
Osmosis is the movement of water that occurs within cells through a semipermeable cell membrane. This process is performed from a medium with lower water concentration to another with higher concentration.
In osmosis, the solvent (water) is passed from one medium to another across a cell membrane. This process does not cause energy waste and therefore osmosis is considered a passive transport. In the osmosis process, water, which is the solvent, tends to cross the semipermeable membrane in order to balance the solution concentration. This action is performed until the osmotic pressure is stabilized.

The carbon dioxide absorbed by plants is an example of an ________ to a forest and an ________ from the atmosphere.
The carbon dioxide absorbed by plants, such as those in forests, is an input to the forest ecosystem and an output from the atmosphere. The forest acts as a carbon sink, storing carbon, while the atmosphere acts as a carbon source, supplying carbon dioxide. The balance of these processes influences atmospheric carbon dioxide levels and climate change.
Explanation:The carbon dioxide absorbed by plants functions as an input to a forest and an output from the atmosphere. This concept is part of the biological carbon cycle, where carbon moves between the atmosphere and various ecosystems. Plants, or autotrophs, absorb carbon dioxide from the atmosphere in a process known as photosynthesis, and incorporate this carbon into high energy compounds like glucose. Therefore, forests become carbon sinks as they lock away this carbon.
Meanwhile, the atmosphere functions as a carbon source, continuously providing carbon dioxide. The burning of fossil fuels, for example, releases vast amounts of carbon dioxide into the atmosphere, contributing to this carbon source. It's important to note that the rates of these processes greatly influence atmospheric carbon dioxide levels and thus impacts climate change.

Heritability of height is ______ if children have good nutrition and health care, but it is only ______ when they are malnourished.
Base on the researches and studies, the probability or the percentage of an individual to gain the heritability of the height is about ninety five percent, only if the individual is in good shape and in good nutrition but when a person is malnourished and weak, it will only be at twenty percent because heritability wouldn’t be applied as the body responds to a different simulation.
Final answer:
The heritability of height is higher when children have access to good nutrition and health care, underscoring the interaction between genetics and environment. Malnutrition lowers heritability, demonstrating the influence of environmental factors on physical development.
Explanation:
The heritability of height is higher if children have good nutrition and health care, but it is only lower when they are malnourished. This concept illustrates the interaction between genetics and the environment in determining physical traits like height. While genetics provide the potential for an individual's height, environmental factors such as nutrition and health care are crucial in realizing this genetic potential. Malnutrition can severely impact growth, preventing individuals from reaching the height they are genetically predisposed to. Conversely, adequate nutrition and health care support optimal growth and development, allowing the genetic factors that contribute to height to manifest more fully.
It's essential to understand that both genes and environment play significant roles in determining height. Studies estimate that approximately 60% to 80% of height variation can be attributed to genetic differences, with 20% to 40% down to environmental factors, predominantly nutrition. This interaction highlights the complexity of physical development and the critical role that a healthy environment plays in achieving genetic potential.

How can habitat corridors be beneficial to species that need large areas in which to live and move around?
Answer:
A habitat corridor is an area of land that connects to populations and is separate from all human activities such as logging. It can be beneficial because if there were two populations that needed large areas of land they could connect for an even larger area and it would prevent the damaging effects of inbreeding.
Explanation:
A habitat corridor is an area of land that connects to populations and is separate from all human activities such as logging.
What is habitat corridor?It can be beneficial because if there were two populations that needed large areas of land they could connect for an even larger area and it would prevent the damaging effects of inbreeding.
The term "corridor" is prone to misunderstanding and incorrect definition. A habitat corridor is defined by Beier and Noss (1998) as: a linear habitat embedded in a heterogeneous matrix.
A habitat corridor's significance can only be determined by the main habitat it connects. To reach their full potential, corridors depend on a network of already-existing but discontinuous natural areas (dechant).
Therefore, A habitat corridor is an area of land that connects to populations and is separate from all human activities such as logging.
