B. False
What is photosynthesis
Answer:
The process of a plant converting sunlight, carbon dioxide and water into food
Explanation:
Hey there!
Photosynthesis is the reaction that converts light energy to chemical energy in sugar and carbohydrates. Humans can't eat sunlight, so we eat plants. Plants convert the energy in the sunlight into chemical energy using chlorophyll. Chlorophyll is a molecule produced by plants, algae, and cyanobacteria, which aids in the conversion of light energy into chemical bonds. It is the green pigment found in the chloroplasts of higher plants. They are a part of our ecosystem, and they are lower on the food chain.

using Punnett Squares, determine the percentage of offspring which would be heterozygous from the following cross: BB x bb
A. 25%
B. 50%
C. 100%
Lets take that the father has black hair and the mother has brown hair so -->
Male × Female
Genotypes: BB × bb
Phenotypes: Black brown
Gametes: B _100%_ b_100%_
After reviewing the photo
we have
Genotypes
B: 50% (1/2)
b: 50% (1/2)
Phenotypes
Black: 50% (1/2)
brown: 50% (1/2)
Using Punnett Squares, the percentage of offspring would be heterozygous from the following cross: BB x bb is 25%. Therefore, option (A) is correct.
What are the features of punnett square method?The Punnett square is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment. It is named after Reginald C. Punnett, who devised the approach in 1905.
The Punnett square is a table in which all of the possible outcomes for a genetic cross between two individuals with known genotypes are given. In its simplest form, the Punnett square consists of a square divided into four quadrants.
A Punnett Square is a helpful tool that helps to predict the variations and probabilities that can come from cross breeding. This includes predicting crossing plants, animals, even humans with each other.

Do different patterns of electrical signals have unique
meanings?
Answer:
Plants use electric fields to communicate with bees, scientists have learned.
Bumblebees are able to find and decipher weak electric signals emitted by flowers, according to the study.
Tests revealed that bees can distinguish between different floral fields, as if they were petal colours. The electric signals may also let the insects know if another bee has recently visited a flower.
Explanation:
How bees detect the fields is unknown, but the researchers suspect the electrostatic force might make their hair bristle. A similar hair-raising effect is seen when placing one's head close to an old-style TV screen.
Flowers were already known to use bright colours, patterns and enticing scents to attract pollinators.

How are GMO's made????
Answer:
GMOs are created by selecting and inserting a particular gene into a plant to produce a desired trait – such as resistance to pesticides. ... This type of selective or traditional breeding involves crossing thousands of genes, which is different than how gmos are made.
Explanation:
Answer:
GM is a technology that involves inserting DNA into the genome of an organism. To produce a GM plant, new DNA is transferred into plant cells. Usually, the cells are then grown in tissue culture where they develop into plants. The seeds produced by these plants will inherit the new DNA.

An ecological footprint A) is a means of determining increases in populations that lived in the past. B) is a means of understanding resource availability and usage. C) measures dispersion and adaptability. D) will estimate population movements.
Answer: An ecological footprint is a means of understanding resource availability and usage. The correct option is B.
Explanation:
The ecological footprint is a method which is used to measure the rate as which humans use natural resources in their environment and generate waste from them compared with how fast nature can absorb these wastes and generate the used resources again. The productive areas which are measured through this means are:
--> cropland,
--> grazing land,
--> fishing grounds,
--> built-up land,
--> forest area, and carbon demand on land.
The importance of ecological footprint to the environment should no the over emphasizes. When properly observed, different environmental pollution would be dealt with. Generally, there would be:
--> decreased desertification,
--> decreased global warming
--> availability of fresh unpolluted air and
--> decreased carbon emissions.

Hemolysis of red blood cells occurs when the cells are placed in a(n) Group of answer choices hypotonic solution physiological saline solution hypertonic solution isotonic solution
Answer:
Hypotonic solution
Explanation:
Haemolysis of red blood cell refers to the destruction or breakdown of red blood cells. Red blood cell will undergo haemolysis if placed in an Hypotonic solution. Hypotonic solution is a solution that contain smaller amount or lower concentration of solutes like dissolved salt than other solution and also compared to the cystol. If a cell is placed in Hypertonic solution, red blood cell will swell because it will absorb solute and undergo hemolysis burst when placed in a hypotonic solution.

Answer:
When a long-term environmental change occurs, certain individuals in a population will be better adapted for the new environment than others. These individuals will be more likely to survive and pass on their traits to their offspring. Over many generations, these favorable adaptations build up in a population. This may lead to speciation, which is the development of a new species.When a long-term environmental change occurs, certain individuals in a population will be better adapted for the new environment than others.

Answer:
Asexual reproduction.
Explanation:
The generation of genetically identical offspring from a single parent, without the fusion of sperm and egg, is called asexual reproduction. Asexual reproduction occurs when there is only one parent from which organism is produced. Budding, binary fission and fragmentation are the different types of asexual reproduction that involves only one parent and no fusion of sperm and egg cells.

Define el consepto de fraccion
Answer:
The concept of fraction
Explanation:
What is the concept of fraction tho? Fractions are numbers that represent a part of the whole. When an object or a group of objects is divided into equal parts, then each individual part is a fraction. ... It is divided into a numerator and denominator where the denominator represents the total number of equal parts into which the whole is divided.
A fraction represents the number of parts that we take from a unit that is divided into equal parts. It is represented by two numbers separated by a fraction line.

Natural selection results in change over time by acting on traits that are ___
Answer:
passed on, inherited, passed on to offspring, most adapted to the environment or have the best adaptive traits or higher genetic fitness
Explanation:
Natural selection results in change over time by acting on traits that are heritable and advantageous.
What is Natural selection?Natural selection is the differential survival and reproduction of individuals due to the differences in phenotype of the organism. Natural selection is a key mechanism of evolution, the change in the heritable traits characteristic of a population takes place over many generations.
Natural selection is the central mechanisms of evolutionary change in a species and is the process responsible for the evolution of adaptive features in an organism. This selection helps in storing the characteristics which are advantageous and are heritable for the species.
