Answer:

The organism is physically stronger than competing organisms.

Explanation:

The scientific names for two atoms covalently bonded are : Hydrogen and oxygen

Covalent bonding is the sharing of electrons between two atoms. This type of bonding occurs between two or more nonmetals.

Elements formed by covalent bonds are non-metal elements and the atoms that form covalent bonds are non-metal atoms. the scientific names of two atoms that are covalently bonded are ; hydrogen and oxygen to form water

H₂ + O = H₂O

Hence we can conclude that The scientific names for two atoms covalently bonded are : Hydrogen and oxygen.

The kind of population growth depicted by the graph is exponential growth.

It is a kind of population growth that takes place in an environment where the population has no limiting factors.  In order words, there are unlimited resources without any hindrance to the growth of the population.

Such a population grows rapidly as soon as it is able to adapt to its environment and continue growing at maximum biotic potential.

A graphical illustration of the exponential growth usually forms a J shape curve.

The energy required for organisms to respond to the environment comes from the sun.

Light energy, which also comes from the Sun, is essential for photosynthesis, a process in which green vegetables transform carbon dioxide and water into glucose, lipids, proteins, vitamins, nucleic acids, releasing oxygen into the atmosphere.

The sun is the basis of life, because if we analyze the food chain, its base comes from the photosynthetic beings that provide food for this chain to occur.

3 specific tasks you must do while working with Professor Ingo Potrykus on this specific project is plant hybridization, growth recognition and quality of the products obtained.

The answer is to obtain populations with genetic variability. This can be achieved through hybridization or crossbreeding. Hybridization is the fusion of genetically different gametes, which results in hybrid individuals heterozygous for one or more loci.

Butterflies laying their eggs on milkweed plants occurs at community level of the biosphere hierarchy. So, the correct option is (D).

Community is defined as a biological community in which groups of different species interact in a common space. For example, a forest of trees and undergrowth plants, in which animals live and are rooted in soil containing bacteria and fungi, constitutes a biotic community.

It is defined as a group of interacting organisms that may or may not be of the same species as long as they share a common habitat where they interact with each other through symbiotic relationships , eg. mutualism, parasitism, commensalism, or competition.

Thus, butterflies laying their eggs on milkweed plants occurs at community level of the biosphere hierarchy. So, the correct option is (D).

Utilising fossil fuels has a detrimental impact on air quality because they produce dangerous pollutants like carbon dioxide and nitrogen oxides when they are burned.

These contaminants are linked to higher air pollution levels, which can lead to a variety of health problems, such as heart disease and respiratory disorders. The effects of new house construction on air resources are complex.

On the one hand, since burning fossil fuels for energy and releasing building materials can result in the emission of hazardous chemicals, construction may increase air pollution. On the other side, if new homes are constructed in places with fewer air pollution, as in rural regions, they may result in better air quality.

A benefit of walking to work or school an advantage for air resources. Walking does not emit any pollutants into the air, making it a zero-emission mode of transportation.

Additionally, walking lessens traffic on the roadways, which can lessen vehicle-related air pollution. Air resources may suffer if trees or other vegetation are removed. By providing shade, trees not only assist to filter airborne pollutants, but they also help to chill the air. Because air pollutants are not being filtered out as well when trees are cut down, this might result in higher air pollution levels.

Invasive species are plant or animal species that disrupt the ecological balance of ecosystems by their invasive attributes.

Invasive attributes include the ability to spread or multiply at a fast rate, sometimes secreting biological chemicals to inhibit the growth of other species.

Exotic invasive species are invasive species that are introduced, rather than being native to the ecosystem.

The vascular tissues identify as:

a. phloem

b. xylem

Vascular tissues in plants are specialised tissues which transport nutrients and water through the plant. They are made up of two distinct kinds of tissues: xylem and phloem.

Xylem is in charge of carrying water and minerals that are dissolved from the plant's roots to its leaves. It is made up of many cell types, such as tracheids, vessel components, and fibres. Tracheids and vessel elements are long, hollow structures that create lengthy tubes when stacked end to end.

Sugars and other organic compounds are transported from the leaves to the remainder of the plant by phloem. There are two sorts of cells in it: sieve tube elements and cell companions. Sieve tube components are long, narrow cells that run end to end.

Therefore, the vascular tissues identify as:

a. phloem

b. xylem
