Answer:
Invasive species cause harm to wildlife in many ways. When a new and aggressive species is introduced into an ecosystem, it may not have any natural predators or controls. It can breed and spread quickly, taking over an area. Native wildlife may not have evolved defenses against the invader, or they may not be able to compete with a species that has no predators.
The direct threats of invasive species include preying on native species, outcompeting native species for food or other resources, causing or carrying disease, and preventing native species from reproducing or killing a native species' young.
There are indirect threats of invasive species as well. Invasive species can change the food web in an ecosystem by destroying or replacing native food sources. The invasive species may provide little to no food value for wildlife. Invasive species can also alter the abundance or diversity of species that are important habitat for native wildlife. Aggressive plant species like kudzu can quickly replace a diverse ecosystem with a monoculture of just kudzu. Additionally, some invasive species are capable of changing the conditions in an ecosystem, such as changing soil chemistry or the intensity of wildfires.
Here are some examples:
Cogongrass is an Asian plant that arrived in the United States as seeds in packing material. It is now spreading through the Southeast, displacing native plants. It provides no food value for native wildlife and increases the threat of wildfire as it burns hotter and faster than native grasses.Feral pigs will eat almost anything, including native birds. They compete with native wildlife for food sources such as acorns. Feral pigs spread diseases, such as brucellosis, to people and livestock. E. coli from their feces was implicated in the E. coli contamination of baby spinach in 2006.European green crabs found their way into the San Francisco Bay area in 1989. They outcompete native species for food and habitat and eat huge quantities of native shellfish, threatening commercial fisheries.hope this helps!!:)

Answer:
yooo I have the same question
Explanation:
its animalia and plantae
Species that are multi-celled, have nuclei, and photosynthesize can be found only in the kingdoms Animalia and Plantae.
What is kingdom Plantae?Plantae is a kingdom composed of multicellular eukaryotic organisms capable of synthesizing their own foods by performing photosynthesis.
Animalia is another eukaryotic kingdom composed of organisms that cannot produce their own food (i.e, they are heterotrophs).Eukaryotic cells contain cell nuclei and membrane-bound organelles.In conclusion, species that are multi-celled, have nuclei, and photosynthesize can be found only in the kingdoms Animalia and Plantae.

Explanation:
The human immunodeficiency virus (HIV) is a retrovirus (genus Lentivirus) whose genetic material is a positive-sense single-stranded RNA. HIV is known to infect HIVcells of the human immune system such as, for example, macrophages, T cells, dendritic cells, etc., eventually leading to the acquired immunodeficiency syndrome (AIDS). Within host cells, the HIV genome is reverse transcribed into DNA by using a specific enzyme called reverse transcriptase. Then, this DNA is integrated into the genome of the host cell, replicating when the host cell replicates. Moreover, the integrated HIV genome can also be transcribed to produce RNA and proteins capable of infecting new cells.
Most yellow jacket wasps are unable to survive the winter. Typically, only the queen and a few other wasps are able to survive the cold by hibernating.
Which ecological concept best categorizes weather (i.e., temperature) as a limiting factor in yellow jacket wasp survival?
population birth rate
O population death rate
Odensity-dependent factors
O density-independent factors
Answer: density-independent factors
Explanation:
The ecological concept that best categorizes weather (i.e., temperature) as a limiting factor in yellow jacket wasp survival is referred to as density-independent factors.
Density-independent factor, is also referred to as limiting factor, and it simply means the things that have an impact on the population of the living things in a particular area without taking into consideration of the density of the population for the area e.g food limitation, weather conditions, pollutants, fire etc.

According to mendels ______ one copy of a gene is passed randomly from each parent to their offspring. this is why gametes usually have half the usual number of chromosomes.
Answer:
Law of Segregation
Explanation:
Gregor Mendel was a scientist known for experimenting the pea plants in relation to the topic on "Heredity." Under this, he came up with the "Law of Segregation." This states that an organism only receives one gene copy of every gamete once it makes gametes. This is also "randomly selected." This is the reason why only one copy of a gene is passed from each parent to the offspring. In order to check the allele combinations, a "Punnett square" is being used.
Which of the following organisms is an autotroph?
clam
grass
lion
worm
Grass is an example of autotrophic organism.
WHAT MAKES AN ORGANISM AUTOTROPHIC?
Autotrophs are organisms that are capable of synthesizing their own food via the process of photosynthesis (using light) or chemosynthesis (using chemicals). Autotrophs that undergo photosynthesis possess a unique pigment used for capturing light energy called CHLOROPHYLL present in their CHLOROPLAST organelle. Among the options given, grass is an autotroph because it possess chlorophyll that enables it synthesize its own food via the process of photosynthesis.Hence, grass is an example of autotrophic organism.

Select all that are true. A short tandem repeat (STR):
A. Is a repeated sequence of DNA within a gene coding sequence
B. Can only be identified through restriction enzyme digest analysis
C. Is a repeated sequence of DNA in a non- coding sequence
D. Can be composed of a variable number of repeats in different people
E. Is a mutation in a gene
Answer:
C. Is a repeated sequence of DNA in a non- coding sequence
D. Can be composed of a variable number of repeats in different people
Explanation:
Short Tandem Repeats (STRs) are short DNA motifs, i.e., short nucleotide repeat units (generally 2-7 base pairs in size) that may have a different number of repeats among individuals (alleles). Polymorphic STR sequences are very useful genetic markers and therefore they are used for different purposes, e.g., for constructing genome linkage maps, identification of individuals and/or populations, paternity testing, etc. For example, in the USA, the Combined DNA Index System (CODIS) is a databank that stores different DNA profiles based on 13 core STR loci which are used in forensic identity testing.
What influence does acid rain have on seed germination?

A new virus has been identified by DNA sequencing methods in a remote location in the South Pacific. The World Health Organization is very concerned because infection with this virus has a death rate of 20% of all infected individuals and no vaccine is available. This is an example of a(n) _____ disease.
Answer:
an emerging infectious disease
Explanation:
According to the World Health Organization (WHO), an emerging infectious disease can be defined as a newly identified and previously unknown infection in a population that may lead to serious public health concerns at local and/or international level. Emerging infectious diseases usually are caused by pathogenic organisms (like viruses) already present in the environment that acquire the ability to infect a new host species as an adaptive response to changes in ecological conditions. Some examples of emerging infectious diseases include, among others, Ebola virus disease, Chikungunya virus disease, H1N1 Influenza virus disease, etc.

• 10. What do environmental scientists study?
Answer:
See detailed explanation.
Explanation:
Hello!
In this case, since the environmental science is the branch of science that focuses on natural phenomena, impact of the human activities, pollution prevention and many others, we can notice it is also an interdisciplinary science involving biology, ecology, physics, chemistry, zoology and other branches of natural science because it goes over the environment and the living things dwelling into it.
It means that the environmental scientists study how the ecosystems behave, how we can conserve them despite the pollution and human dangerous activity, how they have changed along the years and how they are going to be as the years go by.
Best regards!
Hi! environmental scientists specifically focuses on the surrounding environment, such as air, land and water to protect these natural resources and human health.
