The conditions in the biome greatly affect the plant and animal life it contains because biome has a specific environmental conditions that allows specific organisms to survive and growth in that particular environment. A biome is a collection of plants and animals that have common characteristics for the environment in which they exist. In the cold regions, only those plants and animals survive and grow which has the adaptation and characteristics to that environment.

An organism that is heterotrophic, reproduces sexually, is multicellular, and does not have cell walls belongs to the kingdom of C. Animalia.

The Kingdom of Animalia is a huge phylum of eukaryotic, multicellular organisms that live in heterotrophic environments. As a result, they rely on outside sources for nutrients. Animal cells lack a cell wall, which is found in plant cells, despite the fact that they are unable to create their own food, which is one of the most distinguishing traits of plants.

The majority of animals, with the exception of a few, are motile, which helps them to successfully respond to stimuli and find food, among other things. In general, animals are separated into two groups: vertebrates (animals with a backbone) and invertebrates (animals without a backbone) (animals that lack a backbone).

Answer: The cell membrane is selectively permeable.

Explanation: going thru last year notes

Answer:

Most cells in our body have two versions of each chromosome (Body cells). These cells are called diploid. We grow and replace these cells with identical cells through a cell division called mitosis.

For sexual reproduction, we need to make cells that have only one version of each chromosome (sex cells). These cells are called haploid. These unique cells are made through a cell division called meiosis.  

Explanation:

haploid = 1

diploid= 2 // "di"=2

our body contains 46 chromosomes, half from our dad and a half from our mom. our repoductive contains 23 chromosomes.

A polynucleotide cannot be started during the DNA synthesis process by the enzymes. Only existing chains that are base-paired with the template strand of RNA, not DNA, can be extended with DNA nucleotides. Primase produces this RNA, which is known as a primer.

The process of creating a new DNA molecule officially starts with primer synthesis. The RNA polymerase enzyme primase creates primers, which are brief nucleotide stretches (about 10 to 12 bases long).

Replication origins are the places where the DNA helix opens for the first time. Origins are defined by DNA sequences that are several hundred nucleotide pairs long in simple cells like those of bacteria or yeast.

Camouflage tends to "hide" objects because it breaks up the perceptual pattern of figure-ground.

What is camouflage?

Camouflage is a technique used to make an animal or object indistinguishable from the surrounding environment, to deceive predators or prey, and to avoid detection or capture. As a result, the animal or object is hidden from sight, making it more difficult to detect. The term "camouflage" is derived from the French word "camoufler," which means "to hide or mask."

What is a perceptual pattern?

A perceptual pattern is the way an individual's brain organizes sensory information to create a meaningful experience of the world around them. These perceptual patterns are influenced by a variety of factors, including context, expectation, experience, and attention. To create a perceptual pattern, the brain must filter out irrelevant information and organize the remaining information into a meaningful whole.

What is a figure-ground pattern?

The figure-ground pattern is a visual pattern in which the eye distinguishes between an object or figure (the focal point) and its surrounding background (the ground). The figure is typically the focus of the viewer's attention, while the ground is perceived as the background against which the figure is displayed.

What happens when camouflage breaks up the figure-ground pattern?

Camouflage works by breaking up the figure-ground pattern, making it more difficult for the eye to distinguish between the object and its surroundings. This makes it more difficult for predators or prey to detect the animal or object and therefore increases its chances of survival.

So, the answer is option (c) figure-ground.

When two particles are travelling in the same direction and both of them have a strong positive charge, they will resist one another and the forces will act in the opposite direction.

What is electric force?

The strength of the electrical force between two charges when they come together depends on the nature of the charges. If the charges are similar, the forces will repel one another; otherwise, they will do the opposite.

Accordingly, if two particles are travelling in the same direction and both of them have a strong positive charge, they will resist one another and the forces will act in the other direction.

The correct order of translation going by the illustration would be 2, 1, 3, 4, 5, 7, and 6.

The translation is a process of gene expression during which the genetic codes in an mRNA chain are translated to their respective amino acids which are then linked by peptide bonds to form proteins.

The first step in the translation process is the binding of mRNA to the ribosome. The rRNA then reads the start codon on the mRNA to signal the beginning of the translation process.

Another RNA, the tRNA carrying anticodons then begins to match up with the complimentary codons on the mRNA, releasing the respective amino acid for each codon in the process.

The ribosome creates a bond between successive amino acids while the chain of amino acids continues to grow until the stop codon is reached. Thereafter, the amino acid chain is folded into protein.

Thus, the correct order of the process is 2, 1, 3, 4, 5, 7, and 6.

The factors that create a warming effect at the Earth's surface (positive forcing) are:

a. Carbon dioxide in the troposphere: Carbon dioxide (CO2) is a greenhouse gas that absorbs and re-emits infrared radiation, trapping heat in the Earth's troposphere, which leads to warming.
b. Black carbon aerosols (soot) on ice: Black carbon aerosols on ice surfaces lower the albedo (reflectivity) of the ice, causing it to absorb more sunlight, which accelerates melting and contributes to a warming effect.
c. Cutting rainforests: Deforestation results in the loss of trees, which are carbon sinks. When trees are cut down, they release stored carbon dioxide into the atmosphere, adding to the greenhouse effect and causing warming.
e. Dust emission from human activities: Dust particles can have both cooling and warming effects. However, when they contribute to the darkening of surfaces like ice, they can cause a warming effect similar to black carbon aerosols.
Out of the listed factors, volcano aerosol emissions (d) generally have a cooling effect on the Earth's surface due to the reflection of sunlight by sulfate particles. So, it is not considered a positive forcing factor.

The examples of geological processes that occur slowly is soil erosion and weathering.

Soil erosion is the denudation or wearing away of the upper layer of soil. It is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice, snow, air, plants, and animals.

Soil erosion occurs primarily when dirt is left exposed to strong winds, hard rains, and flowing water. In some cases, human activities, especially farming and land clearing, leave soil vulnerable to erosion.

Removing trees and plants, plowing fields, and overgrazing by livestock disrupts roots that stabilize sediment and soil. These human activities can increase erosion rates 10 to 100 times that of non-human geologic processes.

Jane Goodall was able to closely observe chimpanzee behaviors by employing a unique and groundbreaking approach. She spent extensive time in the field, specifically at Gombe Stream National Park in Tanzania, where she immersed herself in the chimpanzees' natural habitat. Here are some key aspects of her approach:

1. Long-Term Field Study: Goodall conducted one of the longest continuous field studies of any wild animal species, spanning over several decades. This long-term commitment allowed her to establish deep relationships with the chimpanzees and gain their trust.

2. Participant Observation: Goodall adopted a technique called "participant observation," where she actively engaged with the chimpanzees' daily activities. She lived among them, closely observing their behaviors, social interactions, and feeding habits.

3. Non-Invasive Methods: Goodall employed non-invasive methods to study the chimpanzees. She avoided interfering with their natural behaviors and instead used binoculars and cameras to observe from a distance. This allowed the chimpanzees to behave naturally and provided more accurate insights into their lives.

4. Habituation: Goodall and her team gradually habituated the chimpanzees to their presence over time. By spending consistent and non-threatening time in their environment, the chimpanzees became accustomed to their presence, leading to more relaxed and natural behavior.

5. Detailed Record-Keeping: Goodall maintained meticulous records of her observations, documenting individual chimpanzees, their relationships, behaviors, and other significant details. These records formed the foundation for her groundbreaking research and subsequent insights into chimpanzee behavior.

Through her dedication, patience, and pioneering fieldwork methods, Jane Goodall was able to closely observe chimpanzee behaviors, revolutionizing our understanding of these remarkable primates.
