Answer:
smooth and aerodynamic
Explanation:
Seeds are usually smooth, like a baseball, so that they cut smoothly through the air and don't have a lot of wind resistance.
The adaptation that seeds dispersed through ballistochory has smooth and aerodynamic. The correct option is b.
What are adaptations?Adaptation is a biological process that is done by many plants and animals to survive in given conditions. Adaptation is causing the partial or full change in their body or functions to match with the environmental conditions.
Plants with ballistochory means possibly ejects by the seeds full stop this adaptation or evolution happened in which seats are dispersed into many tentacles and seats are dispersed into soils for pollination this comes under wind dispersion.
Seeds launch an angle and release the elastic energy store in the fruit. These adaptations are smooth.
Therefore, the correct option is b. smooth and aerodynamic

Ultra-high-temperature sterilization effectively reduces microbes that cause spoilage. removes only mesophilic microbes. reduces microbes that cause disease. removes all microbes that cause diseases or spoilage. reduces microbes that cause disease or spoilage.
Answer:
kills all microbes that cause disease or spoilage.
Explanation:
There are different methods of sterilization, such as ultraviolet radiation, autoclave mechanisms, etc.
The sterilization mechanisms eliminate the microorganisms completely, thus generating sterile surfaces.
These mechanisms are used with surgical instruments, the operating room environment.
The autoclave method is the most widely used today due to its economical price, its ease of use and its practicality.
Sterilization methods must be strictly controlled with pilot or test microbiological cultures to be able to corroborate that these mechanisms function correctly, since otherwise they could trigger strong pathologies due to cross contamination.

• How the knowledge of classification be applied to assess the characteristics of different organisms when visit to zoo, herbaria or gardens.(Students may do research on internet to answer this question )
plz correct answer
be quick
Answer:
Compare two organism on the physical features and mode of nutrition.
Explanation:
Organisms are classified in groups and sub-groups on the basis of similarities and differences. so in order to compare two organisms, start with the similarities that are present between them. If similarities are more so they belong to the same group or if differences are more than both are placed in different groups. for classification, see the physical appearance of organism, mode of nutrition and habitat etc. If organisms are identical, they belong to the same species, if one or two characters are different so their genus will be same but specie is different. In zoo animals are different from the animals which is present in garden so compare the physical features of zoo and garden animals.

Bacteria-Kingdom Monera
Explanation:
The classification of the organisms into five kingdoms is as follows:
Mushroom- Kingdom FungiMoss- Kingdom PlantaeEarthworm- Kingdom AnimaliaVolvox- Kingdom ProtistaBacteria- Kingdom MoneraWhat is classification?Classification is distributing the organisms into different groups according to their similar characteristics. The five kingdom classification is the approved form of classification today.
The five kingdoms are Monera, Protista, Fungi, Plantae, and Animalia, and the organisms are distributed in these kingdoms.

The role of Langerhans cells is that they prevent pathogens from entering the body using antibacterial agents.
What are Langerhans cells?Langerhans cell is a dendritic cell of the skin and mucosa, containing Birbeck granules, and present in all layers of the epidermis but most prominent in the stratum spinosum.
Langerhans cells play important roles in the immune system by acting as the outermost guard of the cutaneous immune system where they induce the first reactions against pathogens encountered via the skin.

it is necessary in mammals and birds to separate oxygenated and deoxygenated blood because this makes their circulatory system more efficient and helps in maintaining a constant body temperature
Glycolysis and gluconeogenesis are opposing pathways in that they begin or end with the same metabolites and share common intermediates and/or enzymes. Yet, for energetic reasons, the two processes cannot be the exact reverse of each other. How is this possible
Answer:
Due to difference in their products.
Explanation:
Glycolysis and gluconeogenesis are not exact reverse to each other because in glycolysis, glucose is converted into pyruvate, adenosine triphosphate (ATP), NADH, protons i.e. hydrogen ions and water whereas in gluconeogenesis, pyruvate is converted into glucose and glycogen. So due to the formation of different products of each process we can say that glycolysis is not exact reverse of gluconeogenesis.
Why is it necessary to separate oxgynated blood and deoxgynated blood in living organisums?

Before working at the hospital, Beth was given a Mantoux skin test to detect tuberculosis. If it were positive, the site of the test would become hardened and red. What type of response is this?
The options are missing from the question,the missing options are;
a. Anaphylactic
b. Histamine
c. Immediate allergic
d. Delayed allergic
e. B-cell mediated.
The correct answer to the question is option D
DELAYED ALLERGIC.
Delayed allergic response is a type of late response to antigen that occurs 48-72hours after exposure to an antigen.
This type of allergic response is mediated by T-cells and macrophages.
They are otherwise known as delayed hypersensitivity response/reaction.
The response is delayed because there is sensitization upon first exposure to the antigen, therefore if there is a re-exposure,a secondary cellular response is initiated triggering the actions of the already sensitized T-cells and macrophages.

An ecologist samples the abundance of various species along an environmental gradient and fails to find clusters of species. Instead, peaks of abundance of dominant species are merely randomly spaced segments along a continuum. This distribution of species supports the
Answer:
This distribution of species supports Gleason´s Individualistic concept of a community.
Explanation:
This theory was proposed by Gleason and it states that plant species respond individually to environmental factors that continuously change at spatial and temporal levels. This means that the combination and distribution of plants in a certain point or area are unique because each vegetable species has a different distribution pattern and a different tolerance and abundance rate. Hence each species´ response curve to a certain gradient has its own shape and size and it different from other species curves.
Plants assembly growing in an area is the result of environmental conditions and migration rate of species. As every area is continuously getting propagules of different species, the survival success of each plant depends not only in environmental factors, but also depends on the tolerance to other new species and their interactions. This combination along a gradient always results in different composition and abundance of species. This is why a sample can not be confined to a clearly defined vegetable community.
This point of view is known as individualistic or continuum concept of vegetable community. Gleason believed that vegetable species were distributed as a continuum and that communities can not be identified as combinations of associated species that repeat in space.
