What do you call the overall force acting on a object
Answer:
It's called a resultant force.
Explanation:
You see, there may be more than one direction of a force acting on an object so if both forces are of equal strength, the object doesn't move, but if one force is stronger than the other, the resultant force would tilt towards that force and the object would move that direction. It is the resultant force that decides where the object would go based on the forces acting on it.

Explanation:
Describe the situations in which a normal human cell would enter the cell cycle and undergo mitotic cell division. Explain how spindle fibers help ensure the products of mitosis are two identical cells with a full set of chromosomes.
Answer: An example of a specific case is when a skin lesion occurs. Through mitosis, new skin cells are generated to repair damaged tissue. These cells have to be genetically identical to each other. The spindle fibers are structures formed by microtubules extending from one pole to another to orient the duplicated chromosomes in the spindle, bringing them to the position they occupy during metaphase.
Explanation:
Mitosis is a process of cell division that occurs in eukaryotic cells, i.e. cells that have a nucleus where their genetic material is located. This process generates two identical cells with the same DNA, that is, with two identical nuclei, so it does not provide genetic variability except in case of specific mutations. The objective of mitosis is cell multiplication while preserving genetic information. But in general, in mitosis there is an equal distribution of the cell nucleus as well as the rest of the cell content.
The phases of mitosis are as follows:
Interface: The cell duplicates its organelles and its DNA to have twice everything before division.Prophase: The nuclear membrane breaks, the chromosomes condense, the centrosome duplicates and migrates to the opposite poles of the cell forming microtubules. Also, fibers of the mitotic spindle are formed. Prometaphase: The microtubules invade the space where the genetic material is.Metaphase: The replicated chromosomes line up in the middle of the cell, called the equatorial plane.Anaphase: Microtubules separate chromosomes towards the opposite poles. Telophase: The nuclear envelope is re-formed from the remaining fragments of the original.Cytokinesis: A cleavage groove is created in the common cytoplasm of the two new cells where the chromosomes were aligned. The cytoplasm is thus strangled until the membrane allows total separation.Mitosis is then a cellular process that occurs in multicellular organisms to repair damaged tissue, or for growth or development. An example of a specific case is when a skin lesion occurs. When a person suffers an injury, many reactions take place in the repair process to repair the damage including inflammatory, proliferative, and remodeling phases. Through mitosis, new skin cells are generated to repair damaged tissue. These cells have to be genetically identical to each other, to have the same genetic fingerprint and the same function.
The spindle fibers are structures formed by microtubules extending from one pole to another. The kinetochore microtubules attach to the kinetochore, a structure that forms at the centromere of each duplicated chromosome, and orient the duplicated chromosomes in the spindle, bringing them to the position they occupy during metaphase and attracting the newly separated chromosomes to the poles during anaphase.
Spindle fibers has a great contribution in the process of mitosis.
The spindle fibers help to ensure the products of mitosis which is two identical cells with a full set of chromosomes due to attracting the chromosomes towards the poles. Spindle fibers move chromosomes during cell division by attaching to chromosome arms and centromeres and drag the chromosomes towards the pole.
This movement of chromosomes leads to the formation of one parent cell into two daughter cells having equal and same set of chromosomes so we can conclude that spindle fibers has a great contribution in the process of mitosis.

NEED HELP ASAP!!!! Explain why the fact that invasive species did not co-evolve with the native species unbalances an ecosystem.
Answer: The invasive species unbalance an ecosystem because it takes over an ecosystem and does not let the other native species thrive while it takes over. There are many invasive species around the world even in your own town or state there is a type of fish suppose that is an invasive species to Michigan called a sea lamprey which kills fish native to the great lakes and is taking over there are also zebra muscles if you need another example
BRAINLIEST PLZ
Invasive species lack native species' population controls, such as predators, because they did not co-evolve with the other species in the ecosystem. As a result, the population of an invasive species may spread unchecked and eventually throw an ecosystem out of balance.
Unbalances in ecosystem :
A natural or human-caused disruption that throws off an ecosystem's natural balance is known as an ecological imbalance. Both natural and man-made disturbances have the potential to upset an ecosystem's delicate balance. A species' extinction or the introduction of a new species may cause an ecosystem to become ecologically unbalanced.
All the organisms and the physical setting they interact with make up an ecosystem. The nutrition cycles and energy flows connect these biotic and abiotic elements. Photosynthesis is how energy enters the system and is absorbed by plant tissue. Both internal and external influences influence ecosystems. External variables that do not directly affect an ecosystem, such as topography, parent material that creates the soil, and climate, control the ecosystem's general structure. For instance, decomposition, root competition, shade, disturbance, succession, and the kinds of species present all regulate internal variables. While the availability of these resources within the ecosystem is normally governed by internal factors, the resource inputs are often controlled by external activities. As a result, interior variables influence ecological processes as well as being influenced by them.

This a question that you need to apply knowledge of both the digestive system AND biochemistry. You eat
salad with chopped cucumbers, tomato, onion, and Feta cheese with olive oil. Describe the path through the
digestive system of this meal describing how EACH BIOMOLECULE of the meal is digested and absorbed. Discuss all of the organs and enzymes involved.
The main biomolecules present in the meal are carbohydrates but there are also proteins and lipids.
First of all starch will be hydrolysed in the mouth.Saliva contains an enzyme called amylase that turns starch into dextroses and maltose.
In the stomach the HCl will activate the pepsinogen and it will become pepsin that will hydrolise proteins to albumoses and peptones.
Also in the stomach an enzyme called gastric lypase is present which turns lipids into glycerol and fatty acids.
In the duodenum:The pancreas releases pancreatic amylase which turns starch into maltose. It releases pancreatic lypase which turns lipids into fatty acids and glycerol. It releases proteolytic enzymes(trypsin, chemotrypsin, carboxypetidase, elastase, collagenase) which turn proteins, albumoses and peptones into oligopeptides(3-4 aminoacids) and aminoacids.
In the rest of the small intestines enzymes secreted by the cells that line the small intestine work. Oligopeptidases turn oligopeptides into aminoacids. Maltase turns maltose into 2 molecules of glucose. Sucrase turns sacrose into 1 molecule of glucose and one of fructose. Lactase turns lactose into 1 molecule of glucose and 1 of galactose. The intestinal lypase turns lipids into glycerol and fatty acids.

How does the stratigraphic principle help us determine the age of layers of rocks?
Answer:
The principles of stratigraphy help us understand the relative age of rock layers. Layers of rock are deposited horizontally at the bottom of a lake (principle of original horizontal). Younger layers are deposited on top of older layers (principle of superposition). Layers that cut across other layers are younger than the layers they cut through (principle of cross-cutting relationships). The principle of superposition builds on the principle of original horizontal. The principle of superposition states that in an unreformed sequence of sedimentary rocks, each layer of rock is older than the one above it and younger than the one below it. Accordingly, the oldest rocks in a sequence are at the bottom and the youngest rocks are at the top.
gynoceium with United carples is called as
Answer: Gynoceium with united Carples is know as SYNCARPOUS.
Explanation:
The vegetative organs of plants includes the stem, root and leaves. The stem which is the basic organ gives rise to other plant organs which includes the floral organs.
Floral organs are made up of:
--> sepals
--> petals
--> stamens
--> carpels
The carpel is the individual unit of the GYNOECIUM and has a stigma, style, and ovary. GYNOECIUM which is the female reproductive part of flowering plant can be monocarpous (when the carpels occurs in a single form), or apocarpous ( when there are multiple unfused carpels), or SYNCARPOUS (when there are multiple fused carpels).
Answer:
It is considered monocarpous if a gynoecium has a single carpet. If there are several distinct (free, unfused) carpets in a gynoecium, then it is apocarpal. If a gynoecium is "fused" into a single structure with several carpets, it is syncarpic.

Protein is found throughout the body—in muscle, bone, skin, hair, and virtually every other body part or tissue.
What is protein?It makes up the enzymes that power many chemical reactions and the hemoglobin that carries oxygen in your blood. At least 10,000 different proteins make you what you are and keep you that way.
Protein is made from twenty-plus basic building blocks called amino acids.
Because we don’t store amino acids, our bodies make them in two different ways: either from scratch, or by modifying others. Nine amino acids—histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine—known as the essential amino acids, must come from food.
