Answer:
Higher
Explanation:
Molecules such as oxygen move from a higher concentration to a lower concentration across a semi-permeable membrane. This process is called simple diffusion.
Therefore, for oxygen to leave the alveoli and enter the blood, there would need to be a higher concentration of oxygen inside the alveoli and a lower concentration of oxygen in the blood.
Answer:
Hello! Here are the answers:
- Chromosomes are a highly condensed form of a combination of DNA and protein called chromatin. DNA strands (negatively charged) are tightly wound around these proteins called histones (positively charged) to form chromosomes.
- Mechanism genes code for for proteins that govern life processes. These genes or portions of DNA are called exons. DNA segments between these exons are called introns that strictly code for regulatory proteins and also contain genetic regulatory elements (DNA sequences that control gene expression).
- Gene expression is the process of translation of DNA sequences into proteins. The genetic code is the nucleotide sequence in the DNA itself that codes for different amino acids that combine together to form a functional protein.
Explanation:
* 2. The intronic regions are misleadingly referred to as "junk DNA" but introns code for crucial regulatory elements that control gene expression.
* 3. The genetic code determines the sequence of amino acids in various proteins.
Answer:
a life event happens when some benefits are lost to gain other benefits
Ecology
is made up of the science of biology. Ecology is a science that deals with the
relationships between groups of living things and their environments. To exist
with one another, organisms belonging to a same species either compete for the
resources or divide it amongst themselves, where animals and plants of the same
species co-exist and creates a beauty with nature.

1)magnification goes by 10x (read 10 times), 100x,1000x and some goes 10,000x
2)Always focus first using lowest power possible first, switch to medium power (100x) after it's focused on low power(10x), on 100x, use the small knob to focus it more. DO NOT touch the bigger nob when in medium or high power. Switch to high power (100x) when it is focused on medium power, again focus again using the small knob on high power.
3) So it doesn't gather dust and fog up the lense? that one should be self explanatory
