3. Select the correct answer from the list.(1 point)
Increased levels of oxygen in the atmosphere due to photosynthesis caused rates of weathering to ((remain constant, decrease, increase)) which aided in the formation of ((soil, roots, chloroplasts))
1. Plant can thrive due to abundant sunlight for photosynthesis and new, nutrient-rich soil made of cyanobacteria and deteriorating rock.
2. Cyanobacteria were the first photosynthesizing organisms and Cyanobacteria lived in the ocean.
3. Oxygen increase weathering leads to formation of soil.
Factors made the land a place where the first land plants could thrive are abundant sunlight for photosynthesis and new, nutrient-rich soil made of cyanobacteria as well as deteriorating of rock.
Cyanobacteria were the first photosynthesizing organisms that lived on Earth 3 billion years ago. Cyanobacteria live anywhere on the earth where light and moisture is available i.e. in the open oceans, lakes and streams, in soils, hot and cold deserts, hot springs and salty water.
Increased levels of oxygen in the atmosphere due to photosynthesis caused rates of weathering to increase which help in the formation of soil. Oxygen directly take part in the chemical weathering of rocks through the process of oxidation. In this process, oxygen reacts with a substance present in the rock and forms oxides which will result in weathering.

Photosynthesis and cellular respiration are cellular processes in plants and animals
Which statement correctly compares the reactants and products of the two
processes?
The statement that correctly compares the reactants and products of the two
processes is: the reactants of photosynthesis are the products of cellular respiration and vice versa.
PHOTOSYNTHESIS:
Photosynthesis is the process by which green plants obtain their food (glucose) from the energy they derive from sunlight. The equation of photosynthesis is as follows:6CO2 + 6H2O → C6H12O6 + 6O2
CELLULAR RESPIRATION:
Cellular respiration, on the other hand, is the process whereby living organisms obtain energy (ATP) by breaking down food molecules in their cells. The equation for cellular respiration is as follows:C6H12O6 + 6O2 → 6CO2 + 6H2O
From the description of these two processes, it can be said that carbon dioxide and water (reactants of photosynthesis) are the products of cellular respiration and vice versa.Learn more at: https://brainly.com/question/23126016?referrer=searchResults

The undigested, unabsorbed substances called faeces enters into the caecum of the large intestine through ileo-caecal valve, which prevents the back flow of the faecal matter. It is temporarily stored in the rectum till defaecation.
hope it helps you
btw ur intro pls
Feces generally enters into the caecum of the large intestine through the ileocaecal valve
Digestion
Most of the digested foods are absorbed in the small intestines of humans.
Undigested foods, otherwise known as feces are not absorbed but are instead moved into the caecum of the large intestine through a structure known as ileocaecal valve.
The valve prevents the backflow of the feces into the small intestine and the feces are stored in the rectum pending the time they are defecated.

what you know about meiosis, fertilization, genotypes, and phenotypes to describe how traits are inherited. Include predicted ratios of types of offspring. This is a combination of learning objectives 3.18 (meiosis), 3.23 (fertilization), 4.1 on inheritance, and 4.2 on monohybrid crosses. This will require deep thinking about how these four learning objectives are connected.
Meiosis is a type of cell division in which four daughter cells are produced from a single parent cell. In each daughter cell, half number of chromosomes are present. This type of cell division occurs in sex cells such as sperm and eggs.
Fertilization is a process in which a sperm cell successfully meets or combine an egg cell. The newly fertilized cell is called zygote is produced during the process of fertilization.
A genotype is a collection of genes. Genotype is also refer to the two alleles that are inherited for a particular gene. The genotype is expressed when the information encoded in the genes' DNA is used to make protein and RNA molecules.
The term "phenotype" refers to the physical properties of an organism which can be seen. Phenotype includes the appearance, development, and behavior of an organism. An organism's phenotype is determined by its genotype.
Meiosis, fertilization, genotypes, and phenotypes are interconnected to each other because all these terms perform a specific contribution in the process of reproduction.

Compare and contrast light microscopes, scanning electron microscopes, and transmission electron microscopes. Sort each statement into the correct box. some statements may apply to more than one type of microscopes. Some statements may not be used.
Answer: Light microscope:
use a beam of light to produce magnified images
can be used to examine living cells and tissues
Scanning electron microscope:
use a beam of electrons to produce magnified images
can be used to examine DNA
can be used to examine cells
Transmission electron microscope:
use a beam of electrons to produce magnified images
can be used to examine DNA
can be used to examine cells
Explanation: Light microscope: is a commonly used microscope also known as compound microscope. Magnifies images from 40X upto 1000X. It uses ray of visible light to produce a magnified image. The light microscope can be used to view specimen of both living and dead cells or tissues. However, it doesn't give a detailed view of a specimen like electron microscope.
Scanning electron microscope: It uses electron beam as an illuminating source. It has a much higher resolving power than light microscope because it uses electrons instead of light. It magnifies object upto 500000 times the actual size. Internal structures can also be viewed. However, only dead specimen can be used because the beam of electrons can kill the cells. They are of two types:
1. Scanning electron microscope(SEM): an electron beam passes over the specimen's surface and displaces electrons which are then focused on a screen to form an image. Images appear in 3-D
2. Transmission electron microscope: electromagnets magnify the image by passing beam of electrons through a thin specimen. Images appear in 2-D

A DNA segment has base order TCG TAT AAC. Which copy exhibits an insertion mutation without a frameshift?
A. TCG CCG TAT AAC
B. TCG TAT GAAC
C. TCC TAT AAC
D. TCG TAT AC
A. TCG CCG TAR AAC
Explanation:
I JUST DID THIS QUESTION
The nucleotide sequence TCG CCG TAT AAC exhibits an insertion mutation without a frameshift (Option A).
A mutation is any alteration in the nucleotide (DNA) sequence of the genome of an organism.An insertion mutation is a type of mutation where one or more nucleotide bases are added to the original sequence.A frameshift mutation is a type of mutation that alters the open reading frame of the nucleotide sequence, thereby modifying the linear order of amino acids that will be added from the new nucleotide sequence.An insertion mutation of three consecutive nucleotides does not modify the open reading frame of the sequence because they encode for a new codon.In conclusion, the nucleotide sequence TCG CCG TAT AAC exhibits an insertion mutation without a frameshift (Option A).
