Which statement is true of carriers? Select all that apply.
A) They have one dominant allele.
B) They express the recessive trait.
C) They are heterozygous for a recessive disorder.
D) They can pass a gene for a recessive disorder.
B. They express the recessive trait
The carriers for a disease in a pedigree analysis is a heterozygous. They contain a dominant and a recessive allele. Thus, correct options are A, C and D.
What are genes?A gene is a segment of DNA that contains all the information for the development of organism. A carrier in genetics, is an individual who “carries” and can pass on to its offspring an allele associated with a disease and does not show symptoms of that disease. A carrier is an organism that carries two different alleles of a recessive gene and is thus heterozygous for that the recessive gene.
Dominant genetic disorders are those in which a mutation in just one copy of the gene pair is required for the disorder to develop. However, in recessive genetic disorders both alleles need to be recessive for the gene. This disease symptoms are only observed in case of homozygous condition.
Therefore, the correct options are A, C and D.

Answer:
Do you think there is a quantitative relationship between transpiration rate and number or size of leaves on the stem? Explain your answer. Yes, the more leaves a plant has, means more stomata will be available for transpiration. ... Without light to facilitate photosynthesis, most plants close their stomata at night.

how can an understanding of osmosis be important in developing methods for the same storage of food?
Osmosis is also used for preserving fruits and meats, though the process is quite different for the two. In the case of fruit, osmosis is used to dehydrate it, whereas in the preservation of meat, osmosis draws salt into it, thus preventing the intrusion of bacteria.
1. A rapidly increasing human population is the primary driver behind what
LEADING cause of the loss of biodiversity? (SEV5.a) *
O a. Extinction
O b. Habitat Loss
O c. Pollution
O d. Overexploitation
Answer:
your answer is B. Habitat Loss
Explanation:
What is the #1 cause for the loss of biodiversity?
Habitat destruction
Habitat destruction is a major cause of biodiversity loss. Habitat loss is caused by deforestation, overpopulation, pollution, and global warming. Species that are physically large and those living in forests or oceans are more affected by habitat reduction.
Habitat loss and overexploitation, driven by our rapid population growth and unsustainable consumption patterns, are the primary causes of biodiversity loss which is now happening up to ten thousand times faster than for millions of years before.
What do invasive species do when in a new area?
Breed with existing species
Get in balance with the existing food chains
"Take over" the area and become more successful than the native species
Die because they cannot survive
Answer:
"Take over" the area and become more successful than the native species
Explanation:
Invasive species are species that are introduced to a habitat they are not native to. They are environmentally problematic becasue they disrupt native ecosystems in which they are able to thrive. They do not usually breed with existing species, they can disrupt existing food chains, and they wouldn't be invasive if they died out.

what de-polymerizes microtubules to separate sister chromatids during anaphase?
Mitotic spindles depolymerize microtubules to separate sister chromatids during anaphase.
What are microtubules?Microtubules are present inside the cell. They are present in bundles, and they are together with a group of 9 to 11 microtubules. They are rigid and hollow from the inside. They are part of the exoskeleton.
Regarding how chromosomes travel during anaphase A, there are two primary theories. One is that the chromosomes are pulled along the kinetochore microtubules by motor proteins at the kinetochores using the energy from ATP hydrolysis, which causes the microtubules to depolymerize.
Therefore, the microtubules are separated or depolymerized by spindle fibers, to separate the sister chromatids into lines.

Why should we not sleep under peepal tree at night?
This question is partially wrong guys .There is no such danger around peepal tree see the researchs and decide yourself.
some people have written wrong information in this group kindly request you guys to correct wrong information and get new information.
Plants take in carbon dioxide (CO2) and release oxygen (O2) during day time when they undergo the process of photosynthesis and they take in O2 and release CO2 during night as a result of respiration.
There are 3 photosynthesis pathways adapted by plants for carbon fixation namely C3 pathway (Calvin cycle), C4 pathway and CAM pathway (Crassulacean Acid Metabolism). C3 and C4 are common among land plants and among these two, C3 is the most common.
CAM pathway can be seen in desert plants and epiphytes (i.e. plants that live on other plants). Unlike C3 and C4 plants, these plants keep their stomata closed during day and open it during night for fix CO2 in the form of malate and releases O2. They do it so, to prevent loss of water due to sunlight. During the day, they breakdown the malate and use the released CO2 through Kalvin cycle to produce sugars, similar to C3 plants. So, CAM plants releases oxygen during night.
Peepal tree is a hemi-epiphyte in its native habitat i.e. the seeds germinate and grow as an epiphyte on other trees and then when the host-tree dies, they establish themselves in the soil. When they live as an epiphyte, they use CAM pathway to produce carbohydrates and when they live on soil, they switch to C3 type photosynthesis. So, a Peepal tree can also release oxygen during the night depending on whether it is an epiphyte or not.
Other plants that give out oxygen at night are Areca Palm, Neem tree, Snake plant, Aloe Vera, Gerbera and Tulsi.

Ghost can come if anyone sleeps under peepal tree

how can several classification categories be used on the same object????????
Answer: Several classification categories can be used on the same object by characteristics that have been given.
Explanation:
Kingdom:
The highest category into which organisms are classified.
Phylum:
A category used in the classification that consists of one or several similar or
closely related classes. You may also use DIVISION.
Class:
One or several similar or closely related orders. Similar classes are grouped
into PHYLUM.
Order:
One or several similar or closely related families. Similar orders form a
CLASS.
Family:
One or several similar or closely related genera. Similar families are grouped
into an ORDER. The names are usually determined from a type genus (Cactus,
Equus) that is characteristic of the whole family.
Genus (pl. genera):
A number of similar or closely related species. The common name of an organism
is sometimes identical to the genus, e.g. Lilium = lily. Similar genera are
grouped into a FAMILY.
Species:
A group of similar individuals that can breed and produce fertile offspring.
Similar and related species are grouped into a GENUS. Within certain groups,
species may not mate and will under different selection pressures develop
different characteristics form the main population. This is called a
subspecies.
Hope this helps!!!
By characteristics, multiple classification categories can be applied to the same object.
How the classification is done ?
The specificity of the categories within a taxonomic classification increases.Domain, the point of origin for all species, is the most general category in taxonomic classification; One of these domains is shared by all species: Eukarya, bacteria, and archaeaKingdoms are the second taxonomic classification category within each of the three domains, followed by phylum, class, order, family, genus, and species categories.Because they are more closely related, organisms become more similar at each classification category.As inaccuracies in classifications are discovered and rectified, changes to the taxonomic classification of many species must be made as scientific technology advances.A hierarchical model is used in the taxonomic classification system, which is also known as the Linnaean system after its creator, Swedish botanist, zoologist, and physician Carl Linnaeus.The groups get more specific as they move away from the point of origin, until one branch becomes a single species.For instance, scientists divide organisms into three large domains following the common beginning of all life: Eukarya, bacteria, and archaea.A kingdom is a second category that exists within each domain.The following categories of increasing specificity follow kingdoms: family, genus, class, order, phylum, and species.Plants and animals are two types of living things.Plants can be further divided into flowering and non-flowering varieties or grouped according to other characteristics.Insects, reptiles, fishes, mammals, and others are subcategories of animals.To know more about classification check this :
