C o all new cells come from preexisting cells
do all living things are made of one or more cells

Answers

Answer:

A (if it is a multi-answer question) also B. Even also C.

Explanation:

C is definitely not the correct answer because germs and microbes are living things and are made of only 1 cell. The cell is also the smallest unit of life because it is called "the building blocks of life", so it has to be the smallest unit of life. Even C, because cells multiply using an existing cell, just like we humans reproduce. First, it duplicates all of its parts, or contents, including the DNA, then they split to create a new cell,  (or if i'm incorrect, 2).

Tortoise shell cats, like the one shown above, are always femaleWhat scientific phenomenon explains the color pattern of

Answers

Tortoise shell cats can be explained as the offspring from a incomplete dominance cross. Incomplete dominance gives rise to an intermediate phenotype.

The scientific phenomenon that explains the color pattern is X-linked incomplete dominance.

As stated earlier, the tortoise shell colour is as a result of incomplete dominance but as it exists only in females, the inheritance is X linked. This means the tortoise shell colour is inherited in the heterozygous condition as females have two X (XX) and males (XY) can only be either of the parent's true breeding genotype.

all cells life begin and end with this process by the process of meiosis

What is meiosis ?

Meiosis is the process  where a single cell divides twice to produce four four haploid daughter cells which are otherwise called as gametes; It can occur in two substages such as meiosis I and meiosis II.

Humans have 46 chromosomes in every cell,  where 23 chromosomes t came from one of our parents and 23 very similar chromosomes that came from the other parents.

Meiosis I consist of substages like Prophase I where nuclear envelope disintegrates, Chromosomes begin to condense, Spindle fibres appear.

Secondly Prometaphase I where Spindle fibres attach to the  centromere followed by Metaphase I where The homologous chromosomes align at the equatorial plate, Anaphase I where he homologous chromosomes move towards the opposite poles.

Telophase I where Spindle fibres disappear, Cytokinesis I where the cytoplasm and the cell division result in 2 non-identical haploid daughter cells.

Answers

The relationship between the environment, human population and geological events is complex and multidimensional. While human activities can also have significant effects on geological processes, geological events such as earthquakes, volcanic eruptions and climate change can have significant effects on the environment and human populations.

What is an Environment?

The conditions and forces that surround an organism, population or community are called its environment. It includes all elements of the Earth, both living and non-living, such as the atmosphere, hydrosphere, lithosphere, and biosphere.

The environment is a complex system that living things interact with and influence how they survive, develop and thrive. This includes biological elements such as plants, animals, microorganisms and their interactions, as well as physical elements such as temperature, light, water, soil, wind and topography.

Therefore, the relationship between the environment, human population and geological events is complex and multidimensional.

How is a population’s size related to their well-being?

Answers

I'm not sure if this will be correct it's been a while since I did science but the population size influences if the species will survive or go extinct.

According to what I've found on the internet this seemed the easiest explained there are more individuals trying to use the same quantity of resources. This can lead to competition for food, water, shelter, mates, light, and other resources needed for survival and reproduction.
Therefore it affects the well-being of people as they will begin to fight or bump into issues regarding the number of resources they have this could be caused by overpopulation.

Describe Hydrogen Bonding.


BEST ANSWER GETS BRAINLIEST

Answers

Hydrogen bonding is a interaction between two hydrogen atoms that is very essential for life on Earth. It is notoriously seen between water molecules, and it occurs when there is a slight disbalance in electrical charge between two Hydrogen atoms, and Oxygen atom that comprise water.  This slight imbalance makes the Oxygen slightly more electronegative, and the two hydrogen atoms slightly more electropostive.  The reason why water when spilled forms globules for this exact reasoning. The slightly positive charged hydrogen feels an electrostatic attraction to the Oxygen atom thus forming a strong bond. An interesting fact that comes from this electrical disbalance is that when salt is added to water, water is able to conduct electricity because of this disbalance in charge it can seperate the sodium chloride lattices into ions.

Answer:

Acute illnesses generally develop suddenly and last a short time, often only a few days or weeks. Chronic conditions develop slowly and may worsen over an extended period of time—months to years.

Photosynthesis

Explanation:

Just like trees and other plants, grass converts energy from sunlight into sugar through the process of photosynthesis. This energy is used to convert water and carbon dioxide into glucose. Carbon dioxide is absorbed through the stomata in the leaf and water is mainly derived from uptake in the roots. Photosynthesis makes the grass green and healthy.
