Answer:

Option 1: They greatly disrupt existing food webs.

Explanation:

Invasive species: As the name suggests, any organism which is not native to the habitat and disrupts the growth of the existing ecosystem where it invades or is introduced are called invasive species.Examples of invasive species: Red Lionfish, Green Iguana, Longhorn Beetle.Characteristics of invasive species:High tolerance to an adverse environment,Rapid reproductive rate.Enhanced adaptability.Increased dispersal ability.Invasive species have the ability to cause extinction or threat to the native plants and animals. They can also cause destruction to the natural resources found in the place. Harming economic and ecological growth.

#1 The term "phenotype" refers to the observable physical properties of an organism; these include the organism's appearance, development, and behavior. An organism's phenotype is determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes.

#2 Phenotype

#3 Genetics

#4 Gregor Mendel

#5 an allele

#6 Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits.

#7 The nucleus (plural, nuclei) houses the cell's genetic material, or DNA, and is also the site of synthesis for ribosomes, the cellular machines that assemble proteins.

What term can be used to describe all cellular respiration?
Tick one box.
А
Aerobic
B
Endothermic
С
Anaerobic
D
Exothermic

Answers

I think the answer is D because respiration releases energy.

The term that can be used to describe all cellular respiration is Exothermic. Some cellular respiration may be aerobic, some are anaerobic but all the exothermic.

What do you mean by Cellular respiration?

Cellular respiration may be defined as the methodology of transforming glucose into a form of energy (ATP) that is useable by cells.

Respiration that occurs in the presence of oxygen is known as aerobic cellular respiration, respiration that occurs in the absence of oxygen is known as anaerobic respiration.

Therefore, the term that can be used to describe all cellular respiration is Exothermic.

Choose which assumption must be made in order for this estimate of broad-sense heritability to be correct.

a. The phenotypic variance of the genetically identical plants is the same as the genetically variable population.
b. The genetic variance component is strictly the result of additive genetic variance.
c. The environmental variance of the genetically identical plants is the same as that of the genetically variable population.
d. There is no phenotypic variance associated with the environment.

Answers

The assumption 'environmental variance of the genetically identical plants is the same as that of the genetically variable population' is CORRECT. It is used to estimate the variation due to genetic factors.

Heritability (h2) refers to the proportion of the variability of a given phenotypic trait due to genetic factors.

Broad-sense heritability is affected by genetic and environmental factors.

Broad-sense heritability can be estimated as H² = VG/VP, where VG and VP represent genetic variability and phenotypic variability, respectively.

what type of weather is typically associated with the air pressure system near Salem

Answers

Answer:

According to common weather maps of the region surrounding Salem, Massachusets, the weather typically associated with the air pressure system is rain.

Explanation:

Given the nature of warm air and its tendency to rise, warmer regions tend to fall under the low-pressure system category. These systems, due to the movement of the warm air, have lower pressure at their center than in the areas surrounding them. As the wind blows towards the low-pressure air systems, the cooler and warmer air meet within the atmosphere, which causes the water vapor to condense and form clouds. Oftentimes, these clouds then precipitate, causing rain.

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.

Answer:

Living organisms sustain life, based on certain life processes. These life processes help to regulate their daily activities. Excretion is one among them. The metabolism takes place in the cells of living organisms resulting in both useful and toxic products. The accumulation of toxins may harm the organism. Thus, the living organisms remove all these metabolic wastes from their body and this process is called excretion. Different organisms follow different modes of excretion. Let’s have a glance at excretion in plants and how excretion in plants is different from that of animals.

The phrase that best defines the orbit of Earth is the path Earth travels as it revolves around the sun. That is option D.

Rotation of the Earth

The earth is one of the nine planets that makes up the solar system.

An orbit is a regular, repeating path that an object takes around another one.

The earth and other planets travels round the sun. That is to say, the orbit of earth is defined as the path the earth passes through or travels as it revolves around the sun.

The earth rotates about its own axis within 24 hours causing day and night while it travels round the sun in every 365.25 days.
